Definitions
- This invention relates generally to filter devices useful for trapping blood clots and controlling embolization and thrombosis in blood vessels. More specifically, the present invention is directed to a blood clot filter, which has improved self-centering capabilities.
- Blood clots (emboli) which are carried in the blood stream often pose serious threats to a person's health and may lead to death. For that reason, the reduction of such clots and their stabilization and arrest against further migration from the vena cava into the pulmonary circulation are necessary.
- a number of types of permanent filters have been designed for this purpose.
- these filters are in the form of a frustoconical basket which is attached to the interior of a vein downstream of the area sought to be filtered.
- One type includes a plurality of wire legs of the same length extending in a generally conical array from a common apex to their free ends which attach to the wall of the vessel, thus forming a cone of revolution with a single plane of contact with the vessel wall.
- a filter of this type is described in U.S. Patent No. 3,952,747.
- the filter shown therein includes sharpened hooks at the free wire ends to permanently anchor the filter by impaling the hooks in the blood vessel.
- the filter in theory, would be centered. In reality such perfect deployments rarely occur and so the filter is often deployed in a tipped position, with its apex not coincident with the apex of the vessel.
- U.S. Patent No. 4,688,553 provides for a self-centering filter where at least some of the legs are, towards their free ends, provided with appendices which extend substantially parallel with the substantially cylindrical wall of the vessel when the filter is inserted within the vessel and whereby each appendix includes a portion extending in the general direction of the apex from which the legs radially diverge and up the vena cava wall. It is the appendices which allow for centering of the filter inside the vein.
- a disadvantage of this filter is its inability to be easily retrieved. As the appendices of these filters extend in the direction of the apex, the ends thereof would increase interference with the venal wall upon removal thereby rendering removal more difficult.
- a general disadvantage of the conical filters of the type described above is that the flexibility of the wires prevents consistent bearing forces from being applied to the vein wall. Moreover, the wire is small, and the bearing surface in contact with the vein is restricted which can lead to trauma and perforations.
- filters formed from a conical portion of wire legs are generally difficult to load before emplacement due to the interference of the hooks with each other when the filter is folded into the ejector used for emplacement.
- the filter once the filter is ejected and implanted, it cannot be removed. This often results in permanent placement of the filter in an undesirable location and often requires the placement of another filter at the appropriate location.
- U.S. patent No. 5,152,777 describes a self-centering filter with resilient filter wires designed for temporary emplacement within a vessel.
- the filter is of the same general conical design as the aforementioned filters except that the filter wires have rounded tips instead of hooks at their free ends to facilitate removal.
- a longitudinally stable stem is permanently affixed to the collar at the vertex of the filter. Once emplaced in the body, the stem remains attached to the filter and serves to keep the filter centered in the vessel and to facilitate retrieval.
- This filter therefore has a separate centering portion, consisting of the stem, and a separate trapping/filtering portion consisting of the conical filter wire portion.
- a disadvantage of this filter is that it is not firmly anchored to the vessel wall due to the rounded tips at the free wire ends. The filter, even when open, may be moved horizontally within the vessel. This can allow clots to escape the filter. Yet another disadvantage of this filter is that because the stem needs to remain for centering purposes, the patient's immune system suffers the burden of the presence of a larger foreign body. In addition, an obturator needs to be inserted in the lumen of the stem to prevent stagnant blood from accumulating in the lumen and forming potentially dangerous emboli.
- the present invention provides a two-planar filter with improved centering capabilities due to its two planar points of contact with the inner venal wall.
- Contact at two planes is provided by the contact of two sets of filter wires wherein each set differs in length from the other.
- centering capability is additionally improved by providing at least some of the filter wires, preferably in the set of wires of lesser length, with extensions. Barbs, e.g. hooks, are attached to at least one set of filter wires to ensure firm anchoring to the venal wall.
- Having two planar points of contact has the added benefit of reducing the profile of the filter, which improves ease of emplacement and allows for insertion in veins of lesser diameters.
- the filter design is versatile in that it allows for filter wires which are straight, corrugated or spiral in design, as well as filter wires which have any combinations of straight, corrugated or spiral portions intermediate their length. Each design presents its own advantages.
- Figure 1 shows a conical filter typical of the prior art which has been deployed in a skewed position with respect to a vein in which it is implanted.
- Figure 2 A is generally a longitudinal cross-sectional showing an embodiment of the filter of the present invention positioned in a vein.
- Figure 2B is a transverse schematic showing of the filter of Figure 2 A.
- Figure 3 A shows a further embodiment of the filter of the present invention having two sets of filter wires of differing length and containing corrugated U-shaped portions.
- Figure 3B is a top plan view of the embodiment of the present invention of Figure 3A.
- Figure 4 A shows an additional embodiment of the filter of the present invention having two sets of spiral filter wires of differing length.
- Figure 4B is a top plan view of the embodiment shown in Figure 4 A.
- FIG. 5 shows a still further embodiment of the filter of the present invention.
- a vena cava filter 1 typical of the prior art is shown positioned inside a vein 2.
- Filter 1 includes an apex 3 and a plurality of wires 4 extending generally from apex 3 in a conical configuration.
- the distal ends of wires 5 may include thereon hooks 6 which assist in placing and fixing the filter 1 to the vein 2 at a desired location.
- a simple single plane conical filter 1 of the type shown hereinabove due to its construction has a tendency to be deployed with its axis 7 clearly crosswise in relation to the axis 8 of the vein 2, the direction of blood indicated by the arrow at 9. Deployment of a filter in a skewed position such as shown in Figure 1 gives the perception that the filter will not work optimally.
- FIGS. 2 A and 2B show a vena cava filter 10 for placement in a blood vessel such as vein 2.
- Filter 10 which may be partially formed of stainless steel, titanium, or nitinol, includes two sets of filter wires 11 and 12, each set differing in length from the other.
- the two sets of filter wires 11, 12 diverge from a common apex 13 at one end and extend radially outwardly therefrom.
- the sets of filter wires 11, 12 include respectively opposed, free ends 14, 15 attachable to a wall of a blood vessel 2 such that the free ends 14 of one set of filter wires are anchored at a location spaced from the location of anchoring of the free ends 15 of the second set of wires.
- the filter wires 11 have ends 14 lying in one place while the filter wires 12 have ends 15 lying in a second place longitudinally spaced therefrom. This arrangement thereby effects a two- planar filter with an emboli-capturing array of filter wires.
- the filter wires 11 which are of shorter length, contact the venal wall 2 at a first plane 16 and the filter wires of longer length 12 contact the venal wall 2 at a second plane 17 spaced longitudinally in terms of the direction of blood flow which is indicated by the arrow at 9.
- the wires 11, 12 from each of the two sets extend from apex 13 where they are regularly circumferentially spaced apart one with respect to the other, so as to define a cone of revolution. It is preferred that the shorter wires 11 be inter- digitated with the longer wires 12 so that the filter wires of one length radially alternate with filter wires of a second, different length to form the two planar design.
- At least one of the sets of filter wires includes anchoring barbs, e.g. hooks 18, at the free wire ends 15 in contact with the vein inner wall at 2 to help secure the filter in position.
- the hooks are present on the set of filter wires 12 of longer length.
- the hooks may be present on the set of shorter length.
- each of the sets of filter wires may include hooks at the free wire ends. Where each of the sets of filter wires include hooks at the free ends, each of the two sets of hooks will be at a different plane, thus allowing for a reduced profile when the filter is compressed.
- each set of hooks at a different plane provides for an increase in the ease of emplacement due to less interference of the hooks with each other when the filter is folded into the ejector for emplacement.
- the filter wires 11 and 12 extend in a generally linear direction from the apex 13 toward the wall of the vein at 2.
- the use of linear filter wires results in a reduced profile upon compression, making emplacement within the vein easier and allowing insertion into veins of smaller diameter to be possible.
- the filter By providing a two point contact at different planes, the filter has the advantage of improved centering such that the apex of the filter is generally coincident with the axis of the vein. This establishes a single filtering element having two planes of contact with the vein wall, which also provides for centering of the filtering element. In addition, having contact at two planes reduces the collapsing of the cava by reinforcement of the walls. By increasing the supporting area to include two planes of contact, the contact pressure on the vein walls originating from each of the wire ends decreases, which in turn reduces trauma to the vein walls. In addition, the filter reduces the force that would be required to retrieve the filter should it be medically necessary to do so. A reduction in the force necessary to remove the filter is due to the distribution of the force over two planes of contact. This results in an increase in ease of removal and a decrease in damage to the architecture of the blood vessel upon removal.
- a two plane filter 20 includes a central apex 21 and two sets of filter wires 22, 23 extending therefrom.
- Each of the filter wires 22, 23 extend in a corrugated fashion from the apex 21 of the filter.
- the corrugated portions 24 may be of a general U-shaped design as depicted in Figures 3 A and 3B. Alternatively, the corrugated portions 24 may simply have multi-angular linear segments. It can be appreciated that, wherein the angles depicted in Figures 3 A and 3B are generally right angles, any angles can be used to form the corrugated portions. Corrugations, in general, provide for more effective fibrinolysis of the emboli.
- the filter wires 22 of shorter length make contact with the venal wall 2 at a first plane 25 whereas the filter wires 23 of longer length make contact at a second plane 26.
- each of the filter wires contain hooks 27 at their free ends 28 for anchoring to the venal wall shown at 2 in Figure 3B.
- only one of the two sets of filter wires may include hooks.
- the corrugated portions 24 in Figures 3 A and 3B are shown on both sets of filter wires 22, 23, it may be appreciated that the corrugated portion 24 may be used on only one set of the filter wires 22, 23. It is also under the contemplation of the present invention that at least one of the filter wires may include linear portions interrupted by corrugated portions intermediate the length thereof.
- FIG. 4 A and 4B A still further embodiment of the invention is shown in Figures 4 A and 4B.
- a two plane filter 30 includes an apex 31 having a plurality of filter wires wherein at least one of the filter wires, represented by 32, 33, 34 and 35 extends in a spiral fashion from the apex 31.
- hooks 36 are positioned on a set of filter wires of a set length at 34. Hooks at 36 allow anchoring of the filter to the inner venal wall at 2.
- wires 34 with hooks 36 radially alternate with wires 35 of a different length containing no hooks.
- each set of wires of a different length may include hooks at the free wire ends.
- wires of a shorter length represented by 32 make contact with the venal wall at a first plane 37, whereas the longer wires, represented by 33, make contact at a second plane 38.
- hooks may be positioned on one of the sets of filter wires.
- a two plane filter 40 includes first and second sets of filter wires 41 and 42 extending from a common apex 43.
- a set of filter wires 41 includes one wire extension 44 extending from the distal end 45 thereof. Extensions 44 may be integrally formed with wires 41. In this way, when the filter is inserted into the vein, the extensions 44 are applied against the walls of the vein 2 and compel the filter to adopt a position with its axis generally coincident with the axis of the vein, thus improving its centering upon deployment and providing additional stability.
- extensions provide an even broader supporting area, which decreases the trauma owing to contact pressure on the vein walls. It is also noteworthy that extensions may also favor satisfactory hooking of the filter in the vein and better tolerance, making it possible to reduce the aggressiveness of the anchoring hooks as a result of the larger anchoring surface which the appendices offer.
- hooks 46 are provided on the wires 42 of longer length for anchoring at plane 47. These wires radially alternate with wires 41 of a shorter length which contact the wall 2 at a different plane at 48. The direction of blood flow is indicated by the arrow at 9.
- the extensions may include anchoring hooks at their free ends.
- extensions 44 which extend in a downward direction with the vessel wall increases the ease of removal of this filter relative to a filter-type with extensions extending in a direction toward the apex of the filter. This is because the ends of the downwardly-directed extensions 44 would not be expected to interfere with the venal walls upon removal.
- the filter wires 41 provided with the extensions 44 are shorter than filter wires 42. In this way, when the filter is introduced into the vein the wires 41 provided with the extensions 44 are the first to be applied against the inner wall of the vein and so center the filter before the other longer filter wires 42 are deployed and become hooked into the inside of the vein.
- each extension 44 can be a bent portion located at the distal end 45 of the shorter of the two sets of filter wires 41 as depicted in Figure 5.
