Abstract

A deflation device including a catheter having a proximal opening at a proximal end and a distal opening at a distal end; and a coring member disposed within the catheter and comprising a handle disposed near the proximal end of the catheter, a cable, and a coring tip disposed near the distal end of the catheter; wherein pressing said distal end of said catheter against said wall of said balloon creates a substantially normalized surface of said balloon relative to a coring tip and wherein the coring tip is a sharpened, hollow cylinder. A method for deflating and removing an implantable, inflatable device comprising: pressing a distal end of a catheter against the wall of an inflated balloon of an implanted device; advancing the coring tip within the catheter beyond the distal end of the catheter and into the balloon, whereby a hole adapted for advancing the catheter is created in the wall of the balloon; and advancing the catheter into the balloon.

Claims

1. A method, comprising:

pressing a distal end of a catheter against a wall of an inflated balloon of an implanted device, whereby a substantially normalized surface of said balloon relative to a coring tip is created;

advancing said coring tip within said catheter beyond said distal end of said catheter and into said balloon, whereby a substantially circular cored opening is created in said wall of said balloon.

2. The method of claim 1, wherein said substantially circular cored opening is adapted for receiving said catheter.

3. The method of claim 1, further comprising advancing said catheter through said substantially circular cored opening into said balloon.

4. The method of claim 1, wherein an outer diameter of said catheter forms a seal with said substantially circular cored opening.

5. The method of claim 1, further comprising retracting said coring device from said balloon.

6. The method of claim 1, further comprising removing contents of said balloon through said catheter.

7. The method of claim 1, wherein said coring tip is advanced into said balloon while applying an external pressure lower than an internal pressure within said balloon, wherein said external pressure is applied at a point of contact between said distal end of said catheter and said wall of said balloon.

8. The method of claim 1, wherein said coring tip is advanced into said balloon while rotating said coring tip.

9. The method of claim 1, wherein said coring tip is advanced into said balloon while delivering energy to said coring tip.

10. The method of claim 9, wherein said energy is a longitudinal oscillation applied at a frequency in the ultrasound range.

11. The method of claim 9, wherein said energy is radiofrequency energy.

12. An improved medical device, comprising, in combination:

a catheter having a proximal opening at a proximal end and a distal opening at a distal end; and

a coring member disposed within said catheter and further comprising a handle disposed near said proximal end of said catheter, a cable, and a coring tip disposed near said distal end of said catheter;

wherein said coring tip is a sharpened, hollow cylinder.

13. The device of claim 12, wherein said coring tip is configured to puncture a wall of a balloon when pressed against a portion of said wall of said balloon.

14. The device of claim 12, wherein said distal end of said catheter is configured to create a substantially normalized surface of said balloon relative to said coring tip without puncturing said wall of said balloon when pressed against a portion of said wall of said balloon.

15. The device of claim 12, further comprising at least a luer connector assembly disposed adjacent to said proximal end of said catheter.

16. The device of claim 12, wherein said cable is configured to transfer to said coring tip at least one of torque, tension, and compression applied to said handle.

17. The device of claim 16, further comprising a threaded mating between said handle and a portion of said catheter, said threaded mating be configured to facilitate rotation of said coring member during longitudinal advancement thereof.

18. The device of claim 12, wherein said catheter is configured to operation within a working channel of a flexible endoscope.

19. A kit, comprising:

a catheter having a proximal opening at a proximal end and a distal opening at a distal end; and

a coring member disposed within said catheter and comprising a handle disposed near said proximal end of said catheter, a cable, and a coring tip disposed near said distal end of said catheter;

wherein said coring tip is a sharpened, hollow cylinder;

and directions for use.

20. The kit of claim 19, further comprising a flexible endoscope having a working channel, said catheter being configured to operate within said working channel.
