Definitions
- This invention is an implantable vaso-occlusive coil which is implanted using minimally invasive surgical techniques. It is a complex, helically wound coil made up of a primary helically wound coil which is then wound into a specific secondary shape.
- the secondary shape is itself a series of helical turns. At least a portion of the turns in the secondary shape form a cylindrical region and adjacent that region on at least one end is a conical region which tapers from a diameter approximating that of the central cylindrical region to a smaller diameter.
- the device is desirably self- forming upon exit from the distal end of a delivery catheter.
- the conical tipped vaso-occlusive device may also utilize thrombus-enhancing filamentary material.
- Vaso-occlusive devices are surgical implements or implants that are placed within some opening in the human body. Typically the opening is either within the vasculature or some other region which is to be occluded. Such other sites include fallopian tubes and bile ducts. They are delivered typically via a catheter. It is intended that the devices either block the flow of blood through a vessel making up that portion of the vasculature via the formation of an embolus. An embolus may also be formed within an aneurysm stemming from a normal vessel by use of this invention.
- helically wound vaso-occlusive coil One such widely used device is the helically wound vaso-occlusive coil. Many such coils are dimensioned to engage the walls of the vessels or other sites they are intended to occlude. Other significantly less stiff helically wound devices have also been described in the literature.
- Ritchart et al. A patent describing an early vaso-occlusive device which patent, parenthetically, also provides an excellent background to the vaso-occlusive technology at that time is Ritchart et al. (U.S. Patent No. 4,994,069).
- Ritchart et al. describes a vaso-occlusive coil that assumes a linear helical configuration when stretched and a folded, convoluted configuration when released from the catheter. The stretched condition is used in placing the coil at the desired site via passage through the catheter. The coil assumes a relaxed configuration — which is better suited to occlude the vessel — once the device is released from the catheter.
- Ritchart et al describes a variety of secondary shapes including "flower" shapes and double vortices.
- vaso-occlusive coils having attached fibrous elements in a variety of secondary shapes is shown in Chee et al. (U.S. Patent No. 5, 304,194).
- Chee et al. describes a helically wound device having a secondary shape in which the fibrous elements extend in a sinusoidal fashion down the length of the coil. These coils, as with the Ritchart et al. coils, are produced in such a way that they will pass through the lumen of a catheter in a generally straight configuration and, when released from the catheter, form a relaxed or secondary shape in the lumen or cavity chosen within the human body.
- the fibrous elements shown in Chee et al. enhance the ability of the coil to fill space within the vasculature and to facilitate formation of an embolus and subsequent allied tissue.
- U.S. Patent No. 5,234,437 shows a coil which is helically unwound from a pusher having an interlocking surface.
- U. S. Patent No. 5,250,071, to Palermo shows an embolic coil assembly using interlocking clasps mounted both on the pusher and on the embolic coil.
- U. S. Patent No. 5,261,916, to Engelson shows a detachable pusher- vaso-occlusive coil assembly having an interlock ball and keyway-type coupling.
- This invention is a vaso-occlusive device comprising a helically wound coil which is formed by winding a wire into a first helix or form; the first helix is then itself wound into a secondary form.
- the secondary form is one which, once ejected from a delivery catheter, forms a shape having conical section at each opposing end, which conical end diameter decreases to the furthermost points of the device. It generally forms a "submarine" type shape.
- the vaso- occlusive device is of a size and shape suitable for fitting within a vascular cavity
- Fibrous materials may be woven into the member or tied or wrapped onto it.
- the device may be made in a variety of ways. Typically, the member is helically wound in a generally linear fashion to form a first or primary winding. After completion of that step, the primary winding is then wound around an appropriately shaped winding fixture or form and the so-wound assembly is heat treated to help it retain its shape after removal from the winding fixture. Auxiliary fibrous materials are then added by weaving, tying, or other suitable permanent attachment methods.
- the device is used simply by temporarily straightening device and introducing it into a suitable catheter, the catheter already having been situated so that its distal opening is within the mouth of the vascular cavity or opening to be filled. The device is then pushed through the catheter and, upon its ejection from the distal end of the catheter into the vascular cavity, assumes its relaxed shape.
- the device is typically used in human vasculature to form emboli but may be used in any site in the human body or occlusion such as one produced by the inventive device is desirable.
- Figure 1 shows a side view of a variation of the inventive vaso-occlusive device having but a single cone-shaped end and a cylindrical center section.
- Figure 2 shows a side view of another variation of the inventive device having conical portions at each end.
- Figure 3 shows another variation of the inventive device in which the angles of the two conical ends of the device are substantially different.
- Figure 4 shows a cross section of the Figure 3 device showing the interior of fiber placement.
- Figure 5 is a close-up partial side view of a primary coil useful in this invention showing tufted fibers.
- Figure 6 shows an electrolytically erodible joint useful in deploying this inventive vaso-occlusive device.
- Figure 7 is a partial cross section side view of a mechanically detachable joint suitable for use with this invention.
- This invention is a vaso-occlusive device comprising one or more vaso- occlusive helical coils which are formed by winding a wire into a first helix; the first helix is then wound into a secondary form.
- the secondary form may be held or restrained within a tubular body such as a catheter or introducer into a shape which approximates the shape of the interior of that tubular body.
- the secondary form is one which, when ejected or pushed from the delivery catheter has a plurality of turns at least one substantially conical portion adjacent to a central cylindrical portion having a diameter approximating the larger end of the conical end.
- the device has opposing conical ends separated by a cylindrical coil section.
- FIG 1 shows the most basic variation of (100) of the basic inventive device.
- vaso-occlusive device (100) has a generally cylindrical section (102) also known as the mid-section (102) made up of a number of turns (103) helically wound of a primary coil which in turn was helically wound from a wire.
- the end section (104) has a large end which continues on from the primary winding of central section (102) and creates a taper in section (104) and the taper becomes smaller and smaller as the axis of the coil proceeds.
- the coil may have a pitch (105) which is fairly loose, that is to say, that the distance between windings in the secondary shape are at least equal to the diameter of the primary coil making up those helical windings.
- This looseness prevents the coil from forming a fixed or pipe-like mass so readily after it has been placed within the human body. This looseness also creates a secondary shape having a fairly large mass in the vasculature which decreases the length of the coil placed within the catheter so to decrease the amount of friction encountered when deploying the coil.
- a tightly wound coil producing the same deployed coil volume may not be deployable because they simply refuse to be pushed through the catheter using normal pushing techniques. The loose wind discussed here is desirable but not required.
- the angle of the coil (106) may be virtually any value between 10° and approaching 90°. Indeed in some variations of the invention which may be considered to be variations having non-conic ends, the end section need only be a spirally wound disk.
- the material used in constructing a vaso-occlusive member may be any of a wide variety of materials; preferably, the material chosen is a wire of a radio- opaque material such as a metal or polymer. Suitable metals and alloys for the wire making up the device (100) include the Platinum Group metals, especially platinum, rhodium, palladium, rhenium, and other bio-compatible metals such as tungsten, gold, silver, tantalum, and alloys of these metals. These metals have significant radio-opacity and their alloys may be tailored to accomplish an appropriate blend of flexibility and stiffness. Highly preferred for this service is a platinum/tungsten alloy.
- the wire may also be of any of a wide variety of stainless steels if some sacrifice of radio-opacity may be tolerated.
- Very desirable materials of construction are materials which maintain their shape despite being subjected to high stress.
- Certain "super elastic alloys” include nickel/titanium alloys (48-58 atomic % nickel and optionally containing modest amounts of iron); copper/zinc alloys (38-42% zinc); copper/zinc alloys containing 1-10%) by weight of beryllium, silicon, tin, aluminum, or gallium; or nickel/aluminum alloys (36-38 atomic % aluminum). Particularly preferred are the alloys described in U. S. Patent Nos.
- nickel titanium alloys particularly known as "nitinol”. These nickel titanium alloys are very sturdy alloys which will tolerate significant flexing without plastic deformation even when used as a very small diameter wire.
- the diameter of the coil wire may be significantly smaller than that used when the relatively more ductile platinum or platinum/tungsten alloy is used as the material of construction.
- the coils may be of radiolucent fibers or polymers (or metallic threads or wires coated with radiolucent or radio-opaque polymers) such as Dacron (polyethylene terephthalate or PET), polyglycolic acid, polylactic acid, fluoropolymers such polytetrafluoroethylene, or Nylon (polyamide), or even silk or cotton.
- a polymer is desirably filled with some amount of a known radio-opaque material such as powdered tantalum, powdered tungsten, bismuth oxide, barium sulfate, and the like.
- the coil material is first wound into a primary coil form.
- the primary coil is typically linear after it has been wound and heat treated.
- the diameter of the wire used in the production of the coil will be in the range of 0.0005 and 0.006 inches.
- the wire of such diameter is typically then wound into a primary coil having a primary diameter of between 0.005 and 0.025 inches.
- the preferable diameter is between 0.010 and 0.018 inches.
- the axial length of the primary coil will usually fall in the range of 0.5 to 100 cm, more usually 2.4 to 40 cm.
- the primary coil may well have 10 to 75 turns per centimeter, preferably 10 to 40 turns per centimeter. All of the dimensions here are provided only as guidelines and are not critical to the invention. However, only dimensions suitable for use in occluding sites within the human body are included in the scope of this invention.
- the overall diameter of the device as deployed is generally between 3 and 25 millimeters with a range between 3 and 12 millimeters much more common. If this device is used within an aneurysm in the cranial vasculature, these shapes may be treated using devices having those diameters. Of course, such diameters are not a critical aspect of the invention.
- Figure 2 shows another variation of the inventive device (200).
- the center section (202) is two or more times the length of the axial length of the conical end sections (204, 206).
- the variation (200) also obviously has two opposing ends or sections (204, 206) which are helically wound and have an overall conical shape which is smallest at the opposing extremities of the device.
- a short "tail” such as (208) on the end of the coil which last exits the delivery catheter. This tail (208) prevents the secondary coil turn from hanging in the catheter mouth since the last portion of the device seen by the catheter is straight.
- the wire in this instance is continuous throughout each of the sections of the device.
- Figure 3 shows another variation (300) of the inventive device.
- the central section (302) is quite short in axial length and has but little more than one turn of the coil in the secondary shape within central section (302).
- Terminal conical section (304) is, perhaps, three times the axial length of center section (302).
- the opposing end section (306) is also quite short in axial length.
- the angle of the cone in this variation is found in conical end (306) can approach 90 degrees.
- fibrous materials are also contemplated in this invention.
- fibrous materials have been used in adding to the thrombogenicity of such coils. Including in this group are such well known materials as Dacron (polyethylene terephthalate), polyethylene, polypropylene, silk, Nylon, and cotton.
- the fibrous materials may be added in a variety of ways,
- Figure 4 shows a cross section of the device shown in Figure 3 and it shows that the fibrous materials (308) found therein are looped around in such a way that they are continuous from end to end and generally may be tied to the end of the coil.
- Another variation is had by tying the tuft or wrapping the tuft through the turns of the primary coil. Tufts may be tied at multiple sites throughout the coil to provide a vast area of embolus forming sites.
- Figure 5 shows a close up of a primary coil (310) having a number of tufts (312) passing through the primary turns of the coil and merely being held in place by turns of the coil itself.
- the primary coil may be covered by a fibrous braid such as is shown in U.S. Patent No. 5,382,259, issued January 17, 1995, to Phelps and Van.
- vaso-occlusive coils are held in place before deployment in a variety of different ways so to provide a control on the site and time of their deployment.
- Variations of the invention include the use of electrolytic detachment joints such as is shown in Figure 6 and mechanical detachment joints such as is shown in Figure 7.
- an insulated pusher (402) is attached to the vaso-occlusive coil (404) via an electrolytically erodible joint (406).
- a direct current is applied to pusher (402).
- the current path is, in part, through joint (406) into the ionic medium surrounding the coil upon deployment.
- Such ionic medium is, in the vasculature, blood or saline solution passing through the deploying catheter.
- Joint (406) erodes and allows vaso-occlusive device (406) to remain in the body.
- Vaso-occlusive device (406) may be any of the devices described above with respect to this invention.
- FIG. 7 shows a mechanically detachable assembly (410) partially housed within a deployment catheter (412).
- the vaso-occlusive device itself (414) has an end clasp (416) which engages a similar end clasp (418) forming the end of pusher (420).
- pusher (420) is forwarded distally so that both clasp (416) and clasp (418) are exterior to catheter (412)
- the vaso-occlusive device (415) with its attached clasp (416) is free to stay at the chosen site within the human body.
- vaso-occlusive portion (414) may be any of the devices described above in relation to this invention.
