Abstract

A device for intravascular intervention can comprise an intervention element and an elongate manipulation member. The elongate member can comprise a hooked portion extending about a proximal portion of the intervention element. The hooked portion can have a first segment, a second segment, and a bend between the first and second segments, with the first segment and the second segment located on different sides of the intervention element. At least one of the first segment or the second segment can have an extending portion that extends into a region that is (i) between a top side and a bottom side of the intervention element, and (ii) distal to a proximal part of the intervention element. The extending portion and the proximal part can be aligned such that a line extending in a proximal-distal direction intersects the extending portion and the proximal part.

Claims

1. A device for intravascular intervention, the device comprising:

an intervention element comprising a proximal portion comprising a hole extending therethrough, the proximal portion having a top side, a bottom side, a proximal part, and a middle part, the proximal part having a width greater than a width of the middle part, the middle part being located between the hole and the proximal part;

an elongate manipulation member extending about a proximal portion of the intervention element, the hooked portion comprising a first segment, a second segment, and a bend between the first and second segments, the first segment and the second segment are located on different sides of the proximal portion, at least one of the first segment or the second segment of the elongate manipulation member having an extending portion extending through the hole and into a region that is (i) between the top side and the bottom side, and (ii) distal to the proximal part, the extending portion and the proximal part being aligned such that a line extending in a proximal-distal direction intersects the extending portion and the proximal part; and

a joining element substantially permanently attaching the hooked portion to the intervention element.

2. The device of claim 1, wherein the joining element comprises a band that substantially surrounds at least a section of the elongate member and a segment of the intervention element.

3. The device of claim 1, further comprising a binding agent engaging each of the intervention element, the elongate member, and the joining element.

4. The device of claim 3, wherein the binding agent is a UV curable adhesive.

5. A device for intravascular intervention, the device comprising:

an elongate manipulation member comprising a distally-located attachment portion, the attachment portion comprising a first segment, a second segment, and a bend between the first and second segments; and

an intervention element comprising a proximal end portion and a hole, the proximal end portion having a top side and a bottom side, the hole extending through the proximal end portion between the top side and the bottom side, the attachment portion of the elongate member extending through the hole at the bend such that the first segment and the second segment are located on different sides of the proximal end portion, the proximal end portion comprising a proximal part and a middle part, the middle part being located between the hole and the proximal part, and the proximal part having a width greater than a width of the middle part;

wherein at least one of the first segment or the second segment of the elongate manipulation member has an extending portion that extends into a region that is (i) between the top side and the bottom side of the proximal end portion, and (ii) between the proximal part and the hole, the extending portion and the proximal part being aligned such that a line extending in a proximal-distal direction intersects the extending portion and the proximal part.

6. The device of claim 5, further comprising a band, wherein the band substantially surrounds at least a section of the attachment portion of the elongate member and a segment of the proximal portion of the intervention element.

7. The device of claim 6, wherein the band has an inner diameter that is less than a width of the proximal end portion of the intervention element.

8. The device of claim 6, wherein the band does not extend over the hole.

9. The device of claim 6, wherein the band is crimped onto each of the elongate member and the intervention element.

10. The device of claim 9, wherein the band is crimped onto a retention portion of the intervention element, the retention portion being positioned between the hole and a terminal proximal end of the intervention element.

11. The device of claim 10, wherein the proximal end portion of the intervention element comprises a shoulder positioned laterally of the retention portion, the shoulder extending laterally to an extent, measured from the retention portion, that is greater than or equal to a wall thickness of the band.

12. The device of claim 10, wherein the retention portion extends laterally beyond the attachment portion of the elongate member as viewed from the top.

13. The device of claim 12, wherein, as viewed from the top of the proximal end portion of the intervention element, the retention portion is laterally offset from the attachment portion of elongate member.

14. The device of claim 6, wherein the band is circumferentially continuous.

15. The device of claim 6, wherein the band is radiopaque.

16. The device of claim 6, wherein the band is circumferentially discontinuous and comprises first and second lateral edges, the band having first and second portions adjacent the first and second edges, respectively, that overlap each other.

17. The device of claim 5, further comprising a binding agent attached to the elongate member and the intervention element.

18. The device of claim 17, further comprising a band, wherein the band substantially surrounds the distal portion of the elongate member and a portion of the proximal end of the intervention element.

19. The device of claim 17, wherein the binding agent comprises an adhesive.

20. The device of claim 19, wherein the adhesive is UV curable.

21. The device of claim 5, wherein, as viewed from the top of the proximal end portion of the intervention element, the proximal part underlies the attachment portion of the elongate member and the middle part does not underlie the attachment portion.

22. The device of claim 5, wherein the first segment and the second segment extend generally parallel to each other.

23. The device of claim 22, wherein the elongate manipulation member further comprises a proximal terminal end and a distal terminal end, and the distal terminal end is proximal of the bend of the attachment portion.
