Abstract

A delivery system incorporating a belt for accomplishing relative movement between components of the system. In one aspect, a handle assembly of the delivery system includes a trigger as well as a thumbwheel assembly each configured to activate longitudinal movement of the belt.

Claims

1. A system for delivering a medical device within vasculature, comprising:

a sheath assembly;

a medical device retained in the sheath assembly; and

a handle assembly including a shuttle assembly connected to the sheath assembly, the handle assembly further including a belt attached at one end to the shuttle assembly and at another end to a thumbwheel assembly, the handle assembly further including a trigger attached to the shuttle assembly;

wherein the sheath assembly is attached to the shuttle assembly;

wherein longitudinal movement of the shuttle assembly is alternatively effected by actuation of the trigger assembly and the thumbwheel assembly.

2. The system of claim 1, wherein the belt is arranged vertically at its connection to the shuttle assembly.

3. The system of claim 2, wherein the belt extends proximally from the shuttle assembly to a proximal spool.

4. The system of claim 3, wherein the belt extends distally from the proximal spool.

5. The system of claim 4, wherein the belt is horizontal along a portion of its length when extending distally from the proximal spool.

6. The system of claim 5, wherein the belt is routed about a pair of idlers and a pulley trigger each being in operative cooperation with the trigger.

7. The system of claim 6, wherein the belt extends proximally from the pair of idlers and is connected to the thumbwheel assembly.

8. The system of claim 1, wherein the belt is configured both vertically and horizontally.

9. The system of claim 1, wherein the belt is configured to assume a plurality of turns.

10. The system of claim 1, wherein the belt makes four turns.

11. The system of claim 1, further including a thumbwheel lock.

12. The system of claim 1, wherein the belt has a width and a thickness, the width being greater than the thickness.

13. A handle for delivering a medical device within vasculature, comprising:

a body;

a shuttle assembly housed by the body; and

a belt attached to the shuttle, the belt being configured both horizontally and vertically within the body.

14. A system of claim 13, further comprising a thumbwheel assembly connected to one end of the belt.

15. The system of claim 14, further comprising a trigger operatively attached to the shuttle assembly.

16. The system of claim 15, wherein the thumbwheel assembly includes a thumbwheel spool which takes up a length of the belt when the shuttle assembly is translated proximally.

17. The system of claim 16, further comprising a thumbwheel lock.

18. The system of claim 13, wherein the belt makes a plurality of turns.

19. The system of claim 18, wherein the belt makes four changes of direction.

20. The system of claim 13, wherein actuation of either the thumbwheel assembly or the trigger accomplishes longitudinal movement of the shuttle with respect to the body.
