Abstract

An intracorporeal assembly includes an elongated shaft having a proximal portion and an opposing distal portion, a balloon disposed on the distal portion, and a tubular member disposed about the elongated shaft. The tubular member can slide from the proximal portion to the distal portion of the elongate shaft to surround a portion of the balloon.

Claims

1. An intracorporeal assembly comprising:

a) an elongated shaft having a proximal portion and an opposing distal portion;

b) a balloon disposed on the distal portion; and

c) a tubular member disposed about the elongated shaft such that the tubular member can slide from the proximal portion to the distal portion of the elongate shaft to surround a portion of the balloon.

2. The intracorporeal assembly according to claim 1, wherein the tubular member defines a tubular member lumen having a tubular member length defined by the distance between a tubular member proximal end and a tubular member distal end and a tubular member wall defined by a distance between a tubular member inner diameter and a tubular member outer diameter, wherein the tubular member wall has a tubular member wall inner surface and a tubular member wall outer surface.

3. The intracorporeal assembly according to claim 2, wherein the tubular member comprises a radiopaque marker disposed near the tubular member distal end.

4. The intracorporeal assembly according to claim 2, wherein the elongate member has an elongate member length equal to or less than the tubular member length.

5. The intracorporeal assembly according to claim 2, further comprising a lubricious coating disposed on the tubular member.

6. The intracorporeal assembly according to claim 2, further comprising a lubricious coating disposed on the tubular member wall inner surface and the tubular member wall outer surface.

7. The intracorporeal assembly according to claim 2, further comprising a slit extending through the tubular member wall along a portion of the tubular member length.

8. The intracorporeal assembly according to claim 2, further comprising a slit extending through the tubular member wall along a distal portion of the tubular member length.

9. The intracorporeal assembly according to claim 2, further comprising a slit extending through the tubular member wall along a proximal portion of the tubular member length.

10. The intracorporeal assembly according to claim 2, further comprising a slit extending through the tubular member wall along an entire tubular member length.

11. The intracorporeal assembly according to claim 3, further comprising an eyeloop slidably engaged along the tubular member slit, wherein the eyeloop defines a eyeloop opening extending through the eyeloop.

12. The intracorporeal assembly according to claim 11, wherein the elongated shaft extends through the eyeloop opening.

13. The intracorporeal assembly according to claim 2, further comprising a gripping surface disposed on the tubular member near the proximal end.

14. The intracorporeal assembly according to claim 1, further comprising a guide catheter surrounding a portion of the tubular member disposed about the elongated shaft.

15. A method comprising:

a) placing an elongate shaft having a proximal portion outside a subject vasculature and a distal portion within the subject vasculature;

b) expanding a balloon that is disposed on the distal portion within the subject vasculature;

c) moving a tubular member that is disposed about the elongate shaft from the proximal portion of the elongate shaft to the distal portion of the elongate shaft to surround a portion of the balloon.

d) removing the tubular member, balloon and elongate shaft from the subject vasculature.

16. The method according to claim 15, wherein the expanding a balloon further comprises lodging the balloon within the subject vasculature.

17. The method according to claim 16, wherein the moving a tubular member dislodges the balloon from the subject vasculature.

18. The method according to claim 15, wherein the removing the tubular member, balloon and elongate shaft are removed from the subject vasculature at the same time.

19. The method according to claim 15, wherein the moving a tubular member comprises moving a tubular member disposed about the elongate member from the proximal portion outside a subject vasculature to the distal portion to surround a portion of the balloon within the subject vasculature.

20. The method according to claim 15, further comprising placing the tubular member on the elongate shaft before placing the elongate shaft within the subject vasculature.

21. The method according to claim 15, further comprising placing the tubular member on the elongate shaft after placing the elongate shaft within the subject vasculature.

22. The method according to claim 15, wherein the moving a tubular member comprises moving a tubular member disposed about the elongate member from the proximal portion outside a subject vasculature to the distal portion to surround a portion of the balloon and collapse the balloon within the subject vasculature.

23. The method according to claim 15, wherein the moving a tubular member further comprises sliding an eyeloop slidably engaged in a longitudinal slit along a length of the tubular member in a proximal direction as the tubular member is moved in a distal direction along the elongate member, wherein the eyeloop defines a eyeloop opening extending through the eyeloop and the elongate member extends through the eyeloop opening.

24. The method according to claim 15, wherein the moving a tubular member further comprises moving a tubular member that is disposed about the elongate shaft and within a guide catheter from the proximal portion of the elongate shaft to the distal portion of the elongate shaft to surround a portion of the balloon.
