Abstract

An intravascular device delivery system has an elongated member with an outer sleeve and a distal cap longitudinally fixed to a guidewire receiving member. The guidewire receiving member is moveable longitudinally relative to the outer sleeve to move the distal cap relative to the outer sleeve.

Claims

1. An intravascular device delivery system, the system comprising:

an elongated member with a proximal end, a distal end, and a longitudinal axis therebetween, the elongated member including;

an outer sleeve extending from the proximal end to the distal end,

a guidewire receiving member extending from the proximal end to the distal end, and

a distal cap longitudinally fixed to the guidewire receiving member and configured to engage with a distal end of the outer sleeve.

2. The system of claim 1, further comprising a handle connected to the proximal end of the guidewire receiving member.

3. The system of claim 2, wherein the handle includes a proximal end plate that is longitudinally moveable relative to a body of the handle.

4. The system of claim 3, wherein the proximal end plate is selectively fixable longitudinally relative to the body of the handle.

5. The system of claim 4, wherein the guidewire receiving member is selectively fixed to the proximal end plate.

6. The system of claim 1, wherein the distal cap has a proximal taper.

7. The system of claim 1, wherein the proximal taper comprises a thread.

8. The system of claim 1, wherein the guidewire receiving member is a cable tube.

9. The system of claim 1, further comprising a guidewire having one or more torque transmission features protruding in a transverse direction from a longitudinal axis of the guidewire.

10. The system of claim 9, wherein the distal cap comprises complementary receiving recesses.

11. The system of claim 1, wherein the distal cap and the outer sleeve comprise complementary mechanical connection features.

12. The system of claim 11, wherein the complementary mechanical connection features comprises complementary threads on the distal cap and the outer sleeve.

13. The system of claim 11, wherein the complementary mechanical connection features comprises complementary pins and slots.

14. The system of claim 11, wherein the complementary mechanical connection features comprises snap-fit locking features.

15. The system of claim 1, wherein the distal cap comprises a distal cap end portion and a distal cap ring, the distal cap end portion being received by the distal cap ring coupled to the guidewire receiving member.

16. The system of claim 15, wherein the guidewire receiving member comprises a cut pattern.

17. The system of claim 1, wherein the distal cap comprises a proximal tapered end and a distal tapered end.

18. The system of claim 1, wherein the distal cap comprises a distal cap end portion and a distal cap proximal portion, the distal cap end portion mechanically engaging with a locking ring selectively mounted to the guidewire receiving member.

19. The system of claim 18, wherein the locking ring slidable cooperates with the guidewire receiving member.

20. The system of claim 18, further comprises complementary recess in one of the distal cap end portion and the distal cap proximal portion and a protrusion in the other of the distal cap end portion and the distal cap proximal portion.

21. The system of claim 20, further comprising a fixing material to attach the distal cap end portion and the distal cap proximal portion to the guidewire receiving member.
