Abstract

A device including a clot engaging device having a collapsed delivery configuration and an expanded deployment configuration. The device can include 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 being distally tapered, wherein the distal scaffolding region comprises cells smaller than cells of a remainder of the clot engaging device.

Claims (32)

1. A device, comprising:

a clot engaging device having a collapsed delivery configuration and an expanded deployment configuration, comprising:

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 being distally tapered, wherein the distal scaffolding region comprises cells smaller than cells of 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. The device of claim 1 , wherein the clot engaging device includes a proximal end eccentrically attached to a distal end of a shaft.

9. 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 the clot engaging device, wherein the seam being 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

a distal scaffolding region comprising cells smaller than a remainder of the clot engaging device.

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

11. The device of claim 9 , wherein the seam initiates at a location distal of a proximal end of the clot engaging device.

12. The device of claim 9 , wherein the seam extends along an entire length of the clot engaging device.

13. The device of claim 9 , wherein the clot engaging device includes a proximal end formed with a distal end of a shaft.

14. The device of claim 13 , wherein the clot engaging device is eccentric to the shaft.

15. The device of claim 9 , wherein a proximal end of the clot engaging device includes an open proximal mouth that extends in a plane angled with respect to the longitudinal axis of the clot engaging device.

16. A device, comprising:

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

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 is 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 comprising cells that are smaller than cells of a remainder of the clot engaging device.

17. The device of claim 16 , 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.

18. The device of claim 16 , wherein the seam initiates at a location distal of a proximal end of the clot engaging device.

19. The device of claim 16 , wherein the clot engaging device includes a proximal end formed with a distal end of a shaft.

20. The device of claim 16 , wherein at least some of the plurality of cells include a cell apex.
