Description

EMBOLI CAPTURING DEVICE AND METHOD OF MANUFACTURE THEREFOR
Field of the Invention This invention relates generally to intravascular medical devices. More particularly it relates to a device used for capturing emboli in a fluid vessel during a variety of intravascular medical procedures and a method of manufacture for that device.
Background of the Invention There are a number of intravascular procedures where emboli may be created in the vasculature. It may be desirable to capture these emboli before they flow downstream.
Summary of the Invention
Embodiments of the invention pertain to a device for capturing emboli in fluid flowing in a body vessel lumen and a method of manufacturing the device. Certain embodiments of the invention more particularly pertain to a firame and a filter material portion of the emboli capturing system. In certain embodiments the frame comprises a plurality of proximally fixed elongate members attached to a collar which are expandable into a generally helical pattern. This generally helical pattern of elongate members is configured to open the mouth of the filter to a generally circular shape which contacts the walls of the body vessel lumen to channel the fluid through the filter.
The frame and collar embodiment may be manufactured from a tube of a suitable material such as Nitinol by cutting a number of slits down a substantial portion of the tube and shape setting the elongate members resulting from the slits. This method of manufacture, where the elongate members and the collar are formed from a single tube, provides a ready means of orienting the elongate members with respect to each other and may easily be adapted to frame and filter devices having a different strut configuration.

Detailed Description
The following description should be read with reference to the drawings wherein like reference numerals indicate like elements throughout the several drawings. The detailed description and drawings represent select embodiments and are not intended to be limiting.
Figure 1 is an isometric view illustrating an emboli capturing device 110 constructed in accordance with the principles of the invention. A frame 112 includes a plurality of elongate members 116 and a collar 118. The plurality of elongate members 116 is fixedly connected at their proximal ends 120 to each other and may be attached to a collar 118. Plurality of elongate members 116 is configured so that elongate members 116 will bend outward proximal a distal region 130 of elongate members 1 16 and bend generally helically at distal region 130. Elongate members 116 may also bend generally in a spiral shape proximal distal region 130 of elongate members 116. The elongate members 116 may have a region 132 between the outward bending portion and the generally helical portion whose axis will be generally parallel to the axis running through the center of emboli capturing device 110 both when elongate members 116 are in the expanded position as shown in Figure 1 and the compressed position as shown in Figure 2. A filter material 122 is disposed such that an open end 124 of filter material 122 is proximal a closed end 126 of filter material 122. Plurality of elongate members 116 are attached to filter material 122 at points 128 proximate open end 124 of filter material 122 and extend within filter material 122. Every elongate member 116 may be attached to filter material 122 at points 128 or optionally a lesser number of elongate members 116 may be attached to filter material 122 at points 128. Points 128 are generally located towards the proximal end of distal region 130 and may be located at region 132 to provide an attachment location where filter material 122 is subjected to a minimum of rotational stress.
Emboli capturing device 110 may be disposed on a wire 134 and may be connected to wire 134 at proximal ends 120 of elongate members 116. Filter material 122 may be attached to wire 134 at closed end 126 or may be slideably disposed on wire 134 at closed end 126 of filter material. An atraumatic tip 136 may be attached to the distal end of wire 134.
Emboli capturing device 110 may be compressed within a lumen 138 of a catheter sheath 140 as depicted in Figure 2. As catheter sheath 140 is slid distally over emboli capturing device 110, a distal lip 142 of catheter sheath 140 forces elongate members 116 inward. As elongate members 116 are forced inward, points 128 proximate open end 124 of filter material 122, which is attached to elongate members 116 at points 128, are forced together, collapsing filter material 122 and allowing it to be drawn into catheter sheath 140. When emboli capturing device 110 is compressed in catheter sheath 140, the plurality of elongate members 116 is disposed longitudinally generally parallel to the axis of catheter sheath 140 and filter material 122 collapses from its expanded shape.
If elongate members 116 have a generally spiral shape bend as described above, when elongate members are collapsing, points 128 will rotate and twist filter material 122 during the collapsing process.
Figure 3 shows an end view of frame 112 of emboli capturing device 110 in its expanded position. Elongate members 116 have a bend 154 proximal distal region 130 and a generally helical shape 156 at distal region 130 of elongate members 116. When frame 112 is in the expanded position, the plurality of elongate members 116 may be configured so that distal ends 144 of elongate members 116 overlap the adjacent elongate member 116 such that the perimeter of open end 124 of filter material 122 is given a generally circular shape. This configuration allows filter material 122 to efficiently capture the fluid flow.
Elongate members 116 and collar 118 may be made of any resilient flexible material such as Nitinol, stainless steel, polymer or other suitable material. Bends 154 and generally helical shapes 156 may be molded or shape set into the material.
Filter material 116 may be made of a number of materials well known in the art such as polyethylene meshes manufactured by Saati Tech and Tetko, Inc. An appropriate material may allow blood cells to pass freely through while capturing emboli of a targeted size. Filter material 116 is depicted in the drawings as conical, but many shapes which have an open end and a closed end are suitable for use in embodiments of the invention. Filter material 116 may be disposed on Frame 112 such that open end 124 is either proximal or distal closed end 126, as discussed with respect to Figure 4 below.
Wire 134 may be manufactured from a number of materials commonly used in the art to make guidewires and other wires used in the medical device industry such as stainless steel or Nitinol.
The manufacture of catheters suitable for use as catheter sheath 140 is well known in the art. Catheter sheath 140 may be made from a substantially flexible material such as polyethylene, polymer block amides, nylon, or other suitable material.
Emboli capturing device 110 may be used downstream of a treatment site in the following manner. Emboli capturing device 110 may be inserted into a deployment sheath. Elongate members 116 and filter material 122 may generally be tightly compressed and the deployment sheath may generally be sized to have the minimum outer diameter sufficient to contain emboli capturing device 110. The deployment sheath may then be inserted into a body vessel lumen (not shown), generally percutaneously, and advanced to a location downstream of the treatment site. The deployment sheath may then be withdrawn, allowing elongate members 116 and filter material 122 to reach their expanded state. The treatment site therapy may then be performed. The treatment site therapy may be a variety of intravascular procedures including, for example, balloon angioplasty, stent insertion, or release of a therapeutic agent. If the treatment site therapy creates any emboli, the fluid flowing past the treatment site will flow through the filter material, allowing the emboli capturing device to capture the emboli. When retrieval of the device is desired a retrieval sheath may be distally advanced over the emboli capturing device, collapsing the device as described above. The retrieval sheath may generally have a larger inner diameter that the deployment sheath to accommodate any emboli that may be captured by the device. The retrieval sheath may then be removed proximally from the body vessel lumen together with the emboli capturing device.
Figure 4 shows an isometric view of an emboli capturing device 210 in accordance with the invention. Like emboli capturing device 110, a frame 212 comprises a plurality of elongate members 216 connected at their proximal ends 220 to each other. Elongate members 216 may also be connected at their proximal ends to a collar 218. Frame 212 may have generally the same shape as frame 112. In emboli capturing device 210 however, filter material 222 is positioned such that open end 224 of filter material 222 is distal closed end 226 of filter material 222. Filter material 222 is attached to elongate members 216 proximate open end 224 of filter material 222 at points 228. Points 228 may be located proximate distal ends 244 of elongate members 216.

Figure 5 is an isometric view of a frame 312 according to the invention. Frame 312 may be used with either emboli capturing device 110 or 210. Frame 312 has elongate members 316 connected to each other at proximal end 320 and attached to a collar 318. Collar 318 extends proximally to form a longitudinal catheter like member 352 creating a lumen 350. If frame 312 is used with emboli capturing device 110 in lieu of frame 112, a wire 334 may be extended through lumen 350. Alternatively, member 352 may serve in lieu of proximal portion of wire 334 and one or more elongate members 316 may be made to extend generally parallel to the axis of the emboli capturing device in both the expanded and the contracted state to serve in lieu of the distal portion of wire 334. If frame 312 is used with emboli capturing device 210 in lieu of frame 212, member 352 may serve in place of catheter 240. Frame 312 is suited to manufacturing collar 318 and member 350 from one tube although collar 318 and member 350 may also be made separately and subsequently joined.
Figure 6 is an end view of an alternate frame 412 shown without filter material. Frame 412 comprises collar 418 and elongate members 416. In this embodiment elongate member 416 have a bend 454 and a second bend 458. This embodiment uses the constraint of a filter material 422 (not shown in this figure) and a vessel lumen wall (not shown) to form a distal region 430 of elongate members 416 into a generally helical shape.
Figure 7 is an illustration of a tube 114 which may be formed into frame 112 for use in emboli capturing device 110. The material in slots 162 may be removed to form longitudinal members 116 and collar 118. The material in slots 162 may be removed such that slots 162 have radial walls, parallel walls or such that elongate members 116 have parallel walls. The desired configuration may then be shape-set into elongate members 116. Variations are contemplated where different numbers of elongate members 116 are formed and where elongate members 116 have a variety of cross-sectional profiles. This method of manufacture where elongate members 116 and collar 118 are manufactured from a single tube 114 allows precise positioning of elongate members 116. This method of manufacture may easily be adapted for use with many frame configurations, including other frame configurations disclosed herein.
While the invention is susceptible to various modifications, and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that the invention is not to be limited to the particular forms or methods disclosed, but to the contrary, the invention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the appended claims.
