Abstract

The invention relates to a device and method for approximating two vessels. The device includes a first catheter and a second catheter. The second catheter is slidably disposed in the first catheter. A first expansible member is disposed on the first catheter, and a second expansible member is disposed on the second catheter. The medical device also includes a locking mechanism for interlocking the first catheter and second catheter to prevent relative movement between the first and second catheters.

Claims

1. A medical device comprising:

a first catheter;

a second catheter slidably disposed within the first catheter;

a first expansible member disposed about the first catheter;

a second expansible member disposed about the second catheter; and

a locking mechanism for interlocking the first catheter and the second catheter to prevent relative movement between the first catheter and the second catheter.

2. The medical device of claim 1, wherein the second catheter comprises a lumen longitudinally disposed therethrough for urine drainage.

3. The medical device of claim 1, wherein at least one of the expansible members comprises a balloon.

4. The medical device of claim 1, further comprising at least one inflation tube connected to at least one of the expansible members.

5. The medical device of claim 1, wherein the locking mechanism comprises an interlock hub with a gasket.

6. The medical device of claim 1, wherein the locking mechanism is selected from the group consisting of a springloaded friction lock, a one way ratchet with release override, and a screw lock.

7. The medical device of claim 1, further comprising a urine drainage bag.

8. The medical device of claim 1, further comprising a handle, the handle being coupled to the second catheter for controlling movement thereof.

9. The medical device of claim 8, wherein the handle comprises a manifold.

10. The medical device of claim 1, wherein the second catheter defines at least one opening for receiving bodily fluids.

11. The medical device of claim 1, wherein the second catheter further comprises at least one of a coude tip or a dilator tip disposed at a distal end of the second catheter.

21. The device of claim 1, wherein the first expansible member comprises a portion of the first catheter having a wall section of reduced thickness and the second expansible member comprises a portion of the first catheter having a wall section of reduced thickness.

12. A method for approximating a first vessel and a second vessel comprising:

inserting a catheter assembly comprising a first catheter, a second catheter slidably disposed within the first catheter, a first expansible member disposed about the first catheter, and a second expansible member disposed about the second catheter;

positioning the first expansible member within the first vessel;

inflating the first expansible member;

positioning the second expansible member within the second vessel by sliding the second catheter relative to the first catheter;

inflating the second expansible member within the second vessel; and

sliding the second catheter relative to the first catheter to approximate the two vessels.

13. The method of claim 12, wherein the first vessel is a urethral stump and the second vessel is a bladderneck.

14. The method of claim 12, wherein at least one of the expansible members comprises a balloon.

15. The method of claim 12, wherein at least one inflation tube is connected to at least one of the expansible members.

16. The method of claim 12, further comprising the step of interlocking the first catheter and the second catheter together to maintain a relative position of the first catheter and the second catheter.

17. The method of claim 16, further comprising the step of suturing the ends of the two vessels together.

18. The method of claim 16, wherein the step of interlocking is performed by a locking mechanism.

19. The method of claim 18, wherein the locking mechanism comprises an interlock hub with a gasket.

20. A medical device, comprising:

a first catheter;

a second catheter slidably disposed within the first catheter;

a first expansible member disposed about the first catheter, wherein the first expansible member, when expanded and in contact with an inner wall of a first vessel, provides an intraoperative seal between the first catheter and the first vessel;

a second expansible member disposed about the second catheter, wherein the second expansible member, when expanded and in contact with an inner wall of a second vessel, provides an intraoperative seal between the second catheter and the second vessel; and

a locking mechanism for interlocking the first catheter and the second catheter to prevent relative movement between the first catheter and the second catheter.
