Description
- This application is a divisional of Ser. No. 12/696,863, which is a continuation of U.S. patent application Ser. No. 10/967,065, filed 15 Oct. 2004, and entitled NON-COMPLIANT MEDICAL BALLOON HAVING AN INTEGRAL NON-WOVEN FABRIC LAYER, the specification of which is incorporated herein by reference in its entirety.
- This application is related to U.S. patent application Ser. No. 11/751,489, filed May 21, 2007, and entitled NON-COMPLIANT MEDICAL BALLOON HAVING AN INTEGRAL NON-WOVEN FABRIC LAYER, the specification of which is incorporated herein by reference in its entirety.
- This invention is related to medical balloons, in particular non-compliant medical balloons used with a balloon catheter in medical procedures such as angioplasty.
- Medical balloons have been widely used in medical procedures. Typically, an uninflated medical balloon is inserted into a body-space. When the medical balloon is inflated, the volume of the medical balloon expands, and the body-space is similarly expanded. In procedures such as angioplasty, the medical balloon may be used to open a collapsed or blocked artery.
- Generally, medical balloons have been made of rubber or other compliant substances. To inflate the compliant medical balloons, pressure is increased within the medical balloon, causing the compliant substance to stretch. As more and more pressure is applied to the inner surface of the medical balloon, the medical balloon expands larger and larger until the medical balloon bursts. A typical medical balloon will burst at approximately 7-20 atmospheres or about 100-300 psi.
- One of the principal difficulties in the use of medical balloons in medical procedures is controlling the dimensions of the inflated medical balloon. The pressure introduced must be sufficient to inflate the medical balloon to the proper size, however too much pressure may overinflate the balloon. Overinflating a medical balloon may cause the balloon to expand to a size that may cause stress on the body and may even damage the body. In the worst case, the excess of pressure may burst the balloon, which can lead to serious complications.
- While medical balloons are typically made to close tolerances so that the inflation pressure of the balloon is predictable, variations in the materials used may cause compliant medical balloons to either under-inflate or overinflate for a given pressure. The equipment used to inflate and control the pressure of the balloon must be carefully calibrated and sufficiently accurate to deliver the expected pressure with minimal deviations.
- Medical balloons are commonly used in angioplasty, orthopedics and other medical procedures where it is necessary to force a space within the body.
- Non-compliance, or the ability not to expand beyond a predetermined size on pressure and to maintain substantially a profile, is a desired characteristic for balloons. A non-compliant medical balloon is less likely to rupture or dissect the vessel as the balloon expands. The burst pressure of a balloon is the average pressure required to rupture a balloon; usually measured at body temperature.
- Further difficulties often arise in guiding a balloon catheter into a desired location in a patient due to the friction between the apparatus and the vessel through which the apparatus passes. The result of this friction may be failure of the balloon due to abrasion and puncture during handling and use. Failure may also result from over-inflation.
- Therefore, what is needed is a non-compliant medical balloon that can be inflated with pressure such that the balloon maintains its inflated dimensions without further expanding when additional pressure is applied.
- A non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon. The non-compliant medical balloon is composed of a woven fabric layer composed of at least two woven fabric fibers forming an angle. The angle remains substantially unchanged when the balloon changes from a deflated state to an inflated state.

The figures are not necessarily drawn to scale, and in some instances the drawings have been exaggerated or simplified for illustrative purposes only. One of ordinary skill in the art will appreciate the many possible applications and variations of the present invention based on the following examples of possible embodiments.
- With reference to
FIG. 1A , a cross section of an inflated fiber-reinforcedmedical balloon 10 is shown. With reference toFIG. 18 , a cross section of a deflated fiber-reinforcedmedical balloon 30, is shown. The fiber-reinforced balloon, 10 and 30, is substantially non-compliant, having limited expansion characteristics. As pressure is applied to the interior of a deflatedballoon 30 throughcatheter inlet connector 34, the deflatedballoon 30 inflates. Balloon folds 31 inouter surface 32 decrease the diameter of themedical balloon 30 for insertion. As the deflatedmedical balloon 30 inflates, the balloon folds 31 substantially disappear until theballoon 30 reaches an inflated size, as indicated byballoon 10 inFIG. 1A . Because themedical balloon 10 is non-compliant, once theballoon 10 is fully inflated, it has alength 118 anddiameter 116 that do not change as the pressure on the interior of theballoon 10 increases. - The
diameter 116 of an inflated fiber-reinforcedmedical balloon 10 in accordance with the one embodiment may be about ten millimeters.Balloons 10 with adiameter 116 of about five millimeters to twenty millimeters have been developed. Thelength 118 of an inflated fiber-reinforcedmedical balloon 10 in accordance with one embodiment may be about eight centimeters.Balloons 10 with alength 118 of two centimeters, three centimeters, four centimeters, six centimeters and eight centimeters have been made. The inclination angle of thecone portion 108 of an inflated fiber-reinforcedmedical balloon 10 in accordance with the disclosed embodiment may be about twenty degrees. It will be recognized by those having skill in the art that the fiber-reinforcedballoon 10 could be made in a wide variety ofdiameters 116 andlengths 118 and with a variety of inclinations at thecone portion 108 of the balloon. - The fiber-reinforced
balloon 10 is generally suitable for use as a medical balloon. Medical balloons are commonly used in angioplasty, orthopedics and other medical procedures where it is necessary to create a space within the body. It may be recognized by those skilled in the art that the qualities of a fiber-reinforcedballoon 10 may make theballoon 10 suitable for other uses. The fiber-reinforcedballoons 10 may be used non-medically to create space or otherwise. The fiber-reinforcedballoons 10 may be used in ways beyond the present uses of medical balloons. - The fiber-reinforced
medical balloon 10 may integrally includebase balloon layer 100, a first layer of thininelastic fibers 12 made up of one ormore fibers 13. The fiber-reinforcedmedical balloon 10 may integrally include a second layer of thininelastic fibers 14 made up of one ormore fibers 15. Anouter coating layer 16 may be integrally included in the fiber-reinforcedmedical balloon 10. - Each
fiber 13 is typically fixed relative to other fibers in thefirst fiber layer 12 and other fibers in theballoon 10. The thininelastic fibers 13 of thefirst fiber layer 12 may be characterized by a high tensile strength. As required for medical uses, the fiber-reinforcedballoons 10 provide superior bust strength. The fiber-reinforcedballoon 10 may also resist abrasion, cuts and punctures. It may be recognized that enhanced structural integrity may result from the fiber reinforcement. - With reference to
FIG. 2 , a fiber reinforced medical balloon may include abase layer 100. Thebase layer 100 may be in the shape of a standard medical balloon, or any other suitable shape. A standard polymeric balloon may function as abase layer 100 for the fiber-reinforcedmedical balloon 10. Thebase balloon layer 100 typically includes afirst passage region 102 that may be formed as a narrow cylinder fashioned to attach to the tube of a catheter. Asecond passage region 110 may be similarly formed as a narrow tube. Thefirst passage region 102 is formed adjacent to afirst cone region 104. Thefirst cone region 104 expands the diameter of the first passage region to meet thebarrel region 106, marked by afirst edge 114. Thefirst cone region 104 is typically constructed at an angle of about twelve to twenty degrees. - The
barrel region 106 is characterized by alength 118 and adiameter 116. Thebarrel region 106 meets thesecond cone region 108 at asecond edge 112. Thesecond cone 108 meets thesecond passage region 110. - The
base layer balloon 100 is typically formed of a thin film polymeric material, or other suitable materials with high strength relative to film thickness. Polymers and copolymers that can be used for thebase balloon 100 include the conventional polymers and copolymers used in medical balloon construction, such as, but not limited to, polyethylene, (PET), polycaprolactam, polyesters, polyethers, polyamides, polyurethanes, polyimides, ABS, nylons, copolymers, polyester/polyether block copolymers, ionomer resins, liquid crystal polymers, and rigid rod polymers. Thebase layer balloon 100 may typically be formed as a blow-molded balloon of highly oriented polyethylene terephthalate (PET). - The strength of the fiber-reinforced
balloons 10 permits the use of base layer balloons 100 having awall thickness 120 less than conventional or prior an balloons without sacrifice of burst strength, abrasion resistance, or puncture resistance. In accordance with the disclosed embodiment, thebase layer balloon 100 may have awall thickness 120 of 0.0008 inch. It will be recognized by those skilled in the art that thewall thickness 120 of thebase layer balloon 100 may be diminished as required. Because it is possible for a fiber-reinforcedballoon 10 to omit the PETballoon base layer 100, theballoon wall thickness 120 can be selected to be arbitrarily small. - The
balloon base layer 100 may be omitted from a fiber-reinforcedballoon 10, in accordance with one embodiment. The base layer of apolymer 100, which has been cured into the shape of a balloon may be formed. Thispolymer base layer 100 forms the inner polymeric wall of the fiber reinforced balloon. With reference toFIG. 3 , aremovable mandrel 122 may be used as a base for application of the polymer. After the polymer is cured, themandrel 122 may be removed by standard means such as an application of heat to destructure themandrel 122. - A removable base balloon may be used as the
mandrel 122. Themandrel 122 may be made from a variety of materials. Themandrel 122 may be made in the shape of the interior wall of the desired finished balloon. Themandrel 122 may be made of collapsible metal or polymeric bladder, foams, waxes, low-melting metal alloys, and the like. Once the composite balloon is developed and laminated, the base balloon ormandrel 122 may be removed by melting, dissolving, fracturing, compressing, pressurizing or other suitable removal techniques. - In using the
mandrel 122 arrangement, alternative processing techniques can be employed which do not limit the parameters of temperature, force, pressure, etc., during the lamentation process. The materials used for the balloon construction are not limited to those that conform to the present art of forming a balloon with pressure, temperature and force, such as, for example, those utilized for forming a balloon from a tube made from a polymeric material. Stronger fiber-reinforcedballoons 10, with higher pressure and better damage resistance, can be formed with smaller geometries, in particular balloons having thinner walls. The resulting fiber-reinforcedballoons 10 can be stronger, softer and more flexible. This minimizes the necessary introducer passage while providing higher performance at higher pressures. - With reference to
FIG. 4 , integral layers of the fiber-reinforcedballoon 10 are shown. In accordance a disclosed embodiment, a thin coating of an adhesive 126 is applied to the inflated polymerballoon base layer 100 or to the polymer-coatedmandrel 122 prior to applying the first layerinelastic fibers 12. The adhesive 126 binds thefibers 13 sufficiently to hold them in position when thefibers 13 are placed on thebase layer balloon 100. In accordance with one embodiment, a very thin coat of 3M-75 adhesive 126 is applied to thebase layer balloon 100. 3M-75 is a tacky adhesive available from the 3M Company, Minneapolis, Minn. - With reference to
FIG. 5 , integral layers of the fiber-reinforcedballoon 10 are shown. One ormore fibers 13 are applied to thepolymeric base layer 100 to form afirst fiber layer 12. Thefirst fiber layer 12 may be referred to as the “primary wind.” - The
fibers 13 of thefirst fiber layer 12 may be inelastic fiber, typically made of an inelastic fibrous material. An inelastic fiber is a fiber that has very minimal elasticity or stretch over a given range of pressures. Some fibrous materials are generally classified as inelastic although the all fibrous material may have a detectable, but minimal, elasticity or stretch at a given pressure. - The
fibers 13 of thefirst fiber layer 12 may be high-strength fibers, typically made of a high-strength fibrous material. Some high strength inelastic fibrous materials may include Kevlar, Vectran, Spectra, Dacron, Dyneema, Terlon (PBT), Zylon (PBO), Polyimide (PIM), other ultra high molecular weight polyethylene, aramids, and the like. - In a disclosed embodiment, the
fibers 13 of thefirst fiber layer 12 are ribbon-shaped, where the width of the fiber is larger than the thickness of the fiber. Thefibers 13 may be flat so that the fiber has a rectangular cross-section. Thefibers 13 used in the initial layer offibers 12 may all befibers 13 made of the same material and the same shape.Fibers 13 made from different materials may be used in theinitial fiber layer 12.Fibers 13 made in different shapes may be used in theinitial fiber layer 12. - Ultra High Molecular
Weight Polyethylene fiber 13, which has been flattened on a roll mill may be used to form thefirst fiber layer 12. To the flattenedfiber 13 is applied a thin coat of a solution of polyurethane adhesive in a 60-40 solution of methylene chloride and methylethylketone. Thefibers 13 may be arranged as 30 longitudinal fibers, each substantially equal in length to thelength 118 of the long axis of theballoon 100. - The
fibers 13 of theinitial fiber layer 12, in accordance with the disclosed embodiment, are arranged so that eachfiber 13 is substantially parallel to the long axis of theballoon 100. Longitudinally placedfibers 13 arefibers 13 placed along the long axis of theballoon 100. Thefibers 13 may be parallel to each other. The density of thefibers 13 in theinitial fiber layer 12 is determined by the number offibers 13 or fiber winds per inch and the thickness of thefibers 13. - In a disclosed embodiment of the
first fiber layer 12 having longitudinally-placedfibers 13, a fiber density of generally about 15 to 30fibers 13 having a fiber thickness of about 0.0005 to 0.001 inch and placed equidistant from one another provide adequate strength for a standard-sized fiber-reinforcedmedical balloon 10.Kevlar® fibers 13 may be positioned along the length of theballoon 100 to form thefirst fiber layer 12. Each of thefibers 13 is substantially equal in length to thelength 118 of the long axis of theballoon 100. Twenty-fourfibers 13 may be positioned substantially equally spaced from each other. - The
fiber 13 used for the primary wind may have a thickness of 0.0006 inch.Fiber 13 with a thickness of 0.0005 inch may be used instead. The resultingcomposite balloon 10 is axially and radially non-compliant at very high working pressures. The fiber-reinforcedballoon 10 has very high tensile strength and abrasion and puncture resistance. High strength ultra-high molecular weight polyethylene fiber may be used. - The
first fiber layer 12 may prevent longitudinal extension of the completed fiber-reinforcedballoon 10. The longitudinally placedfibers 13 may be parallel to or substantially parallel to the long axis of thebase layer balloon 100 for maximum longitudinal stability of the fiber-reinforcedballoon 10. - With reference to
FIG. 6 , a cross-section of the integral layers of a fiber-reinforcedballoon 10 is depicted. Abase layer 100 is coated with anadhesive layer 126. Thefirst fiber layer 12 is positioned on thebase layer 100, held at least partially in place by theadhesive layer 126. - In accordance with a disclosed embodiment, a
second fiber layer 14 made with one or more high-strengthinelastic fibers 15 is positioned along circumference of theballoon 100, as shown inFIG. 7 . The circumferentially placedfibers 15 may be transverse or substantially transverse to the long axis of theballoon 100. Thecircumferential fibers 15 may prevent or minimize distension of theballoon diameter 116 at pressures between the minimal inflation pressure and the balloon burst pressure. - The
fibers 15 of thesecond fiber layer 14 may be inelastic fiber, typically made of an inelastic fibrous material. An inelastic fiber is a member of a group of fibers that have very minimal elasticity or stretch in a given range of pressures. Some fibrous materials are generally classified as inelastic although the all fibrous material may have a detectable, but minimal elasticity or stretch at a given pressure. - The
fibers 15 of thesecond fiber layer 14 may be high-strength fibers, typically made of a high-strength fibrous material. Some high strength inelastic fibrous materials may include Kevlar, Vectran, Spectra, Dacron, Dyneema, Telon (PBT), Zylon (PBO), Polyimide (PIM), other ultra high molecular weight polyethylene, aramids, and the like. - In a disclosed embodiment, the
fibers 15 of thesecond fiber layer 14 are ribbon-shaped, where the width of the fiber is larger than the thickness of the fiber. Thefibers 15 may be flat so that the fiber has a rectangular cross-section. Thefibers 15 used in the second layer offibers 14 may all befibers 15 made of the same material and the same shape.Fibers 15 made from different materials may be used in thesecond fiber layer 14.Fibers 15 made in different shapes may be used in thesecond fiber layer 14. - Ultra High Molecular
Weight Polyethylene fiber 15, which has been flattened on a roll mill may be used to form thesecond fiber layer 14. To the flattenedfiber 15 is applied a thin coat of a solution of polyurethane adhesive in a 60-40 solution of methylene chloride and methylethylketone. Thefibers 15 may be arranged as asecond fiber layer 14 may have a fiber density of 54 wraps per inch. Thefibers 15 may be coated with the adhesive solution to form theouter coating layer 16. - The
fibers 15 of thesecond fiber layer 14 may be perpendicular to or substantially perpendicular to thefibers 13 placed longitudinally to form thefirst fiber layer 12. This transverse placement of thefirst fiber layer 12 and thesecond fiber layer 14 allows for maximum radial stability of the fiber-reinforcedballoon 10. The placement of the fiber layers 12 and 14 distributes the force on the balloon surface equally, creating pixelized pressure points of generally equal shape, size and density. - The
fibers 13 of thefirst fiber layer 12 may be the same as or different from thefiber 15 of thesecond fiber layer 14. Specifically, thefibers 15 of thesecond fiber layer 14 may be made of a different material or materials than thefibers 13 of thefirst layer 12. Thefibers 15 of thesecond layer 14 may be shaped differently from thefibers 13 of thefirst fiber layer 12. The characteristics of the fibers or combination of fibers used for the first or second fiber layers may be determined from the specific properties required from the resulting fiber-reinforcedballoon 10. - With respect to the fiber density of the
second fiber layer 14, in accordance with the disclosed embodiment,fiber 15 having a thickness of about 0.0005 to 0.001 inch and arranged in parallel lines with about 50 to 80 wraps per inch provides generally adequate strength. Asingle fiber 15 may preferably form thesecond fiber layer 14, with thefiber 15 wound in a generally parallel series of circumferential continuous loops. - For a standard-sized
medical balloon 10, thesingle fiber 15 may be about 75-100 inches long.Kevlar® fiber 15 may be applied radially around the circumference of and over substantially theentire length 118 of the long axis of theballoon 100. Thefiber 15 has a thickness of 0.0006 inch and is applied at a wind density of 60 wraps per inch. - With reference to
FIG. 8 , a cross section of the integral layers of a fiber-reinforcedmedical balloon 10 is shown. Thefirst fiber layer 12 and thesecond fiber layer 14 may be coated with anouter coating layer 16. Theouter coating layer 16 may be, in the disclosed embodiment, a polymeric solution. Theouter coating layer 16 may be a cured polymeric solution. A fiber-wound basedPET balloon 10 may be coated with a 10% solution of 5265 polyurethane in dimethylacetamide (DMA) that has been allowed to cure at room temperature. Five additional coatings of the polyurethane solution may be used to form theouter coating layer 16. The resulting composite fiber-reinforcedballoon 10 is non-compliant and exhibits superior burst strength and abrasion and puncture resistance. One or more additionalprotective layers 18 may be positioned on theouter coating layer 16, to provide additional layers of protection. - A composite structure typically including
balloon base layer 100, an adhesive 126, afirst fiber layer 12, asecond fiber layer 14 and anouter coating layer 16 forms a composite, non-compliant fiber-reinforcedballoon 10 particularly suitable for medical uses.

It should be noted that these designations are arbitrary and the direction of the warp and weft threads may not correspond to the axis or circumference of a balloon. In the process of weaving, threads are interlaced in different ways to form various weave patterns. It will be recognized that fiber-reinforcedballoon 70 could be made using any suitable fabric, whether woven, knitted, braided or non-woven. - The threads of the fabric may be formed from a variety of substances, typically polymers.

When the binding solution has been applied to thematted fibers 78, the angles between thefibers 78 does not substantially change, regardless of the pressures applied to the surface of thematted fabric layer 77. - The
non-woven fiber layer 75 may be used in place of either thefirst fiber layer 12 or the second fiber layer 24. Thenon-woven fiber layer 75 may be applied from pulp, chopped or other forms of individual fiber elements.

The fiber-reinforcedmedical balloon 10 may be exposed to relatively large amounts of pressure during these procedures. The profile of the deflatedballoon 10 must be relatively small in order to be introduced into blood vessels and other small areas of the body. - With reference to
FIG. 24 , a cross-section of a coaxial catheter tube is shown. A dilatingcatheter assembly 200 may include a coaxialtube catheter tube 208, including anouter channel 210 and aninner channel 212. Thecoaxial catheter tube 208 may be adapted to be inserted into the patient and attached to aconnector structure 230 which enables both the inner 212 andouter channels 210 of thecoaxial catheter 200 to be supplied with medium such as radio-contrast fluid. - With reference to
FIG. 25 , a deflated fiber-reinforcedballoon 10 is shown.Catheter 200 assembly has aninner channel 212 and anouter channel 210 which extend the length of thecatheter tube 208.

FIG. 28 , a blockedvessel 400, such as a blocked coronary artery, havingvessel walls 402 and avessel channel 406 is shown. Thevessel 400 may be blocked bydeposits 404 such as plaque. A fiber-reinforcedballoon catheter 200 may be used to perform angioplasty as a treatment for a blockedartery 400. A fiber-reinforcedballoon 10 may be used to open theheart artery 400 as an alternative to open heart surgery. The fiber-reinforcedballoon catheter 200 for use in angioplasty typically includes a small, hollow,flexible tube 208 and a fiber reinforcedballoon 10 attached near the end of thecatheter tube 208. - A fiber-reinforced cutting balloon, formed with sharp aterotomes attached to the surface of the fiber reinforced
balloon 10, may be used in some cases, particularly where thedeposits 404 are solidified. A fiber-reinforcedballoon 79 with strengtheningrods 124 may be used in some procedures that may use a cutting balloon. In some cases, the strengtheningrods 124 may be used to score theplaque 404, allowing the inflated fiber-reinforcedballoon 10 to open theblockage 404 with less trauma than traditional balloon angioplasty. - The fiber-reinforced
balloon 10 with strengtheningrods 124 may be used for first-time interventions and for subsequent interventions. The fiber-reinforcedballoon 10 with strengtheningrods 124 may be particularly useful where theplaque 404 blockages are resistant lesions, particularly found in positions that are difficult or awkward to address. Bifurcation lesions, for example, occur at the Y-intersection of anartery 400. The inflation and deflation of the fiber-reinforcedballoon 10 with strengtheningrods 124 in this case helps open the blockage without allowing theplaque 404 to shift position. Fiber-reinforcedballoons 10 with strengtheningrods 124 may also be used in the treatment of restenosis. Lesions at the artery origins may also be effectively treated using a fiber-reinforcedballoon 10 with strengtheningrods 124. - Angioplasty typically starts with the patient lying on a padded table. Local pain medicine may be given. Catheters may be inserted in an artery, typically near the groin, in the femoral artery. The
coronary arteries 400 may be remotely visualized by using X-rays and dye. These visualizations permit blockages in the heart vessels to be identified. - With reference to
FIG. 29 , a fiber-reinforcedballoon catheter 200 is shown in an inflated state to open a blockedvessel 400. A fiber-reinforcedballoon catheter 200 may be inserted into thevessel channel 406 or near theblockage 404 and inflated, thus widening or opening the blockedvessel 400 and restoring adequate blood flow to the heart muscle. - More specifically, the technique involves use of a fiber-reinforced
catheter system 200 introduced via the femoral artery under local anesthesia. A pre-shaped guiding catheter may be positioned in the orifice of the coronary artery. Through this guiding catheter a second fiber-reinforceddilation catheter 200 is advanced into the branches of the coronary artery. The fiber-reinforceddilating catheter 200 has an elliptical-shaped distensible fiber-reinforcedballoon portion 10 formed near thedistal tip 220 of thecatheter 200. Theballoon portion 10 can be inflated and deflated. After traversing the stenotic lesion of thecoronary artery 400, the distensible fiber-reinforcedballoon portion 10 is inflated with fluid under substantial pressure which compresses theatherosclerotic material 404 in a direction generally perpendicular to thewall 402 of thevessel 400, thereby dilating the lumen of the vessel 401. - Balloon valvuloplasty, also known as valvuloplasty, balloon dilation or balloon mitral valvuloplasty, is a non-surgical procedure to open blocked heart valves that may use a fiber-reinforced
balloon catheter 200. - The procedure involves the insertion of a fiber-reinforced
balloon catheter 200 into the heart. An incision is made between the atria and thecatheter 200 is moved into the blocked valve. When theballoon catheter 200 is in position, the fiber-reinforcedballoon 10 may be inflated and deflated several times to open the valve. The non-compliance of the fiber-reinforcedballoon 10 under pressure may provide benefits in such procedures. - Fiber-reinforced
medical balloons 10 may be used in the treatment of broken or fractured vertebrae. A fiber-reinforcedmedical balloon 10 may be inserted into the region of the fracture. The minimally invasive procedure may require only a half-inch incision to insert themedical balloon 10. The fiber-reinforcedballoon 10 may be inflated to an appropriate diameter to raise the collapsed bone. The space created by the fiber-reinforcedballoon 10 may be filled with a cementing substance, such as the cement used in hip and knee replacements. - With reference to
FIG. 30 , a fiber-reinforcedmedical balloon 10 for a collapsed or ruptured disc is shown. Thedisk 410 between thevertebrae 408 may cease to separate thevertebrae 408 as shown. With reference toFIG. 31 , a fiber-reinforcedmedical balloon 10 may be inserted between thevertebrae 408 and inflated. The space created by the fiber-reinforcedballoon 10 may be filled with a cementing substance, such as the cement used in hip and knee replacements. - Kyphoplasty may be used in the treatment of pain associated with osteoporotic compression fractures. The procedure helps stabilize the bone and restores vertebral body height. By inflating a fiber-reinforced medical balloon inside the fractured vertebra, the bone position is restored to allow for the injection of medical cement. This procedure stabilizes the fracture and promotes healing. The stabilization alone can provide immediate pain relief for many patients.
- Kyphoplasty is performed through a small incision in the back. A narrow tube, placed in the incision, is guided to the correct position using fluoroscopy. The physician uses X-ray images to insert the fiber-reinforced medical balloon into the tube and into the vertebra. The fiber-reinforced balloon is gently inflated, elevating the fracture and returning the pieces of the vertebra to a more normal position. The inner bone is also compacted, creating a cavity which is filled with medical bone cement that hardens quickly and stabilizes the bone. Alternatively, the medical balloon may remain in the body and bone cement is filled inside the balloon to stabilize the vertebral body.
- Another use of fiber-reinforced medical balloons is in carpal tunnel therapy. Balloon carpal tunnel-plasty may be performed using a fiber-reinforced balloon catheter device. The fiber-reinforced balloon catheter may be used with a specialized nerve protector to stretch and expand the transverse carpal ligament relieving the symptoms of carpal tunnel syndrome. The procedure may be performed through a one-centimeter size incision at the distal palmer crease ulnar to the palmaris longus in line with the fourth ray. The approach is identical to the single portal endoscopic technique. The fiber-reinforced medical balloon is used to dilate and expand the transverse carpal ligament to increase the spatial diameter of the carpal tunnel and relieve pressure on the median nerve alleviating symptoms of carpal tunnel syndrome.
- Fiber-reinforced medical balloons may be used in radiation therapy. Where a tumor has been removed, a fiber-reinforced balloon catheter may be inserted. The inflated fiber-reinforced balloon fills the cavity where the tumor was removed from. Radiation is delivered into the fiber-reinforced balloon periodically.
- Fiber reinforced medical balloons may be used in the treatment of nasolacrimal duct obstruction. Nasolacrimal duct obstruction can cause a condition called epiphora, characterized by chronic tearing. Dacryocystoplasty, a non-surgical treatment, is performed as an outpatient procedure after topical anesthesia. It entails the passage of a fluoroscopically guided wire through the lacrimal duct, followed by dilation of a fiber-reinforced balloon at the site of obstruction.
- Another use of fiber-reinforced medical balloons is the treatment of benign prostatic hypertrophy. A fiber-reinforced balloon is inflated to dilate the prostatic urethra. Balloon urethroplasty is a therapeutic procedure intended to manage symptoms associated with benign prostatic hypertrophy. Under fluoroscopic guidance, a flexible catheter with a fiber-reinforced balloon attachment is placed in the urethra at the level of the prostate above the external sphincter. The fiber-reinforced balloon is then inflated for a short period of time to distend the prostatic urethra. This widening process is intended to relieve obstruction of the urethra caused by the enlarged prostate and to alleviate the symptoms of benign prostatic hypertrophy.
