Abstract

A clot retrieval apparatus 1 comprises a clot engaging device 2 and a capture basket 3. The clot engaging device 2 has a collapsed delivery configuration and an expanded deployment configuration. The clot engaging device has a proximal end and a distal end and an elongate body between the proximal end and the distal end. The capture basket 3 has a collapsed delivery configuration and an expanded deployment configuration. The capture basket 3 has a proximal mouth which is open when the capture basket 3 is in the deployment configuration. The clot engaging device 2 is axially movable relative to the capture basket for capture of a clot.

Claims (32)

1. A device, comprising:

a shaft with a proximal end and a distal end; and

a clot engaging device having a collapsed delivery configuration and an expanded deployment configuration, wherein a proximal end of the clot engaging device is formed with the distal end of the shaft and includes:

a plurality of struts defining a plurality of cells;

a seam extending along at least a portion of a length of a distal end of the clot engaging device, wherein the seam comprises a pattern configured for gripping a clot and extends between cells of the plurality of cells; and

a distal scaffolding region including the distal end being distally tapered, wherein the distal scaffolding region includes cells are smaller than a remainder of the clot engaging device.

2. The device of claim 1 , wherein the seam extends helically about a circumference of the clot engaging device.

3. The device of claim 1 , wherein at least some of the plurality of cells include a cell apex.

4. The device of claim 1 , wherein the seam initiates at a location distal of a proximal end of the clot engaging device.

5. The device of claim 1 , wherein the seam extends through the distal end of the clot engaging device.

6. The device of claim 1 , wherein the seam extends circumferentially about a portion of the clot engaging device.

7. The device of claim 1 , wherein the clot engaging device is self-expandable.

8. A device, comprising:

a clot engaging device having a collapsed delivery configuration and an expanded deployment configuration, wherein the clot engaging device includes:

a plurality of struts defining a plurality of cells;

a seam extending along at least a distal portion of a length of the clot engaging device, wherein the seam comprises a pattern configured for gripping a clot and extends between cells of the plurality of cells circumferentially about at least a portion of the clot engaging device, and wherein the seam is angled with respect to a longitudinal axis of the clot engaging device; and

a distal scaffolding region including a distally tapered distal end, wherein the distal scaffolding region includes cells smaller than a remainder of the clot engaging device.

9. The device of claim 8 , wherein the pattern of the seam extends helically about an entirety of the circumference of the clot engaging device.

10. The device of claim 8 , wherein the seam initiates at a location distal of a proximal end of the clot engaging device.

11. The device of claim 8 , wherein the seam extends along an entire length of the clot engaging device.

12. The device of claim 8 , wherein the clot engaging device includes a proximal end formed with a distal end of a shaft.

13. The device of claim 12 , wherein the clot engaging device is formed eccentrically to the shaft.

14. The device of claim 8 , wherein a proximal end of the clot engaging device includes an open proximal mouth, wherein the proximal mouth extends in a plane angled with respect to the longitudinal axis of the clot engaging device.

15. A device, comprising:

a self-expandable clot engaging device having a collapsed delivery configuration and an expanded deployment configuration, wherein the clot engaging device includes:

a plurality of struts defining a plurality of cells, wherein at least some of the plurality of cells include a cell apex;

a seam extending along at least a distal portion of a length of the clot engaging device, wherein the seam comprises a pattern configured for gripping a clot and extends between cells of the plurality of cells circumferentially about at least a portion of the clot engaging device, and wherein the pattern of the seam is angled with respect to a longitudinal axis of the clot engaging device; and

a distal scaffolding region including that is distally tapered, wherein the distal scaffolding region comprises cells that are smaller than a remainder of the clot engaging device.

16. The device of claim 15 , wherein a proximal end of the clot engaging device includes an open proximal mouth, wherein the proximal mouth extends in a plane angled with respect to the longitudinal axis of the clot engaging device.

17. The device of claim 15 , wherein the seam initiates at a location distal of a proximal end of the clot engaging device.

18. The device of claim 15 , wherein the clot engaging device includes a proximal end formed with a distal end of a shaft.

19. The device of claim 18 , wherein the clot engaging device is formed eccentrically to the shaft.
