Abstract

Medical devices and related systems and methods are described.

Claims

1. A system, comprising:

a catheter defining a lumen;

a handle secured to the catheter; and

a holding device secured to the handle, the holding device configured so that, when a guide wire is disposed in the lumen of the catheter, the holding device can hold the guide wire in a substantially fixed position relative to the catheter.

2. The system of claim 1, wherein the holding device is at least partially disposed within the handle.

3. The system of claim 1, wherein the holding device is secured to an end of the handle.

4. The system of claim 1, wherein the holding device is manually operable.

5. The system of claim 4, wherein the holding device comprises a button configured to be depressed by a user.

6. The system of claim 1, wherein the holding device comprises first and second positions, and

when the holding device is in the first position and a guide wire is disposed in the lumen of the catheter, the holding device holds the guide wire in a substantially fixed position relative to the catheter, and

when the holding device is in the second position and a guide wire is disposed in the lumen of the catheter, the guide wire is free to move longitudinally relative to the catheter.

7. The system of claim 1, wherein, when a guide wire is disposed in the lumen of the catheter, the holding device can bring the guide wire and the catheter into contact with one another.

8. The system of claim 7, wherein the holding device is adjacent an outer surface of the catheter.

9. The system of claim 7, wherein, when a guide wire is disposed in the lumen of the catheter, the holding device can bring the guide wire and an inner surface of the catheter into contact with one another.

12. The system of claim 1, wherein the catheter comprises a first region and a second region, the first region being more compliant than the second region.

13. The system of claim 12, wherein the holding device is configured to deform the first region of the catheter.

14. The system of claim 13, wherein, when the holding device deforms the first region of the catheter and a guide wire is disposed in the lumen of the catheter, the guide wire and the catheter are brought into contact with one another.

19. The system of claim 1, wherein the holding device comprises multiple members, and when a guide wire is disposed in the lumen of the catheter, the multiple members can bring the guide wire and the catheter into contact with one another.

22. The system of claim 1, wherein the holding device comprises at least one spring loaded member.

23. The system of claim 22, wherein the spring loaded member comprises a beam connected to a spring.

26. The system of claim 1, wherein the holding device comprises at least one clamp.

28. The system of claim 1, wherein the holding device comprises at least one inflatable member.

32. The system of claim 1, wherein the holding device comprises at least one magnet.

33. The system of claim 32, wherein the at least one magnet is attached to a beam.

34. The system of claim 33, wherein the beam is configured to move the magnet toward and away from the catheter.

35. The system of claim 1, wherein the holding device is positioned at a proximal region of the system.

36. The system of claim 1, wherein the handle is secured to a proximal region of the catheter.

37. The system of claim 1, further comprising an endoprosthesis carried by the catheter.

38. (canceled)

39. An implantable medical device system comprising:

an inner member defining a lumen;

an outer member configured so that an implantable medical device can be positioned between the inner member and the outer member;

a handle adapted to be secured to at least one of the inner and outer members; and

a holding device adapted to be secured to the handle, the holding device configured so that, when a guide wire is disposed in the lumen of the inner member, the holding device can hold the guide wire in a substantially fixed position relative to the inner member.

40. The system of claim 39, wherein the holding device is at least partially disposed within the handle.

41. The system of claim 39, wherein the holding device is manually operable.

42. The system of claim 39, wherein the holding device comprises a spring loaded member.

43. The system of claim 39, wherein the holding device comprises a clamp.

44. The system of claim 39, wherein the holding device comprises an inflatable member.

45. The system of claim 39, wherein the holding device comprises a magnet.

46. The system of claim 39, wherein the implantable medical device comprises an endoprosthesis.

47. A method of using a medical device comprising a handle secured to a catheter, the method comprising:

activating a holding device secured to the handle, the activated holding device securing an elongate element disposed within a lumen of the catheter to the catheter, a portion of the elongate element and the catheter being disposed within a body vessel of a subject.
