Abstract

An inflated implant within an anatomical structure, such as the bladder, may require removal. A method of removing an inflated implant from an anatomical structure can include any of a number of different steps. A removal device can be placed within the anatomical structure. The implant is located within the anatomical structure. After it is located, the implant can be engaged by arms of the removal device. A portion of a surface of the implant can be compromised such that an inflation substance within the implant can escape. The inflation substance can be removed out of the implant through a deflation tube in at least one of the arms used to engage the implant. The implant can then be removed from the anatomical structure.

Claims

1. A method of removing an inflated implant from an anatomical structure, the implant having been previously implanted within the anatomical structure, the method comprising:

advancing a removal device having at least two arms through a cannula and into an anatomical structure;

locating an implant within the anatomical structure, the implant being in an inflated condition;

capturing the implant with all of the at least two arms of the removal device, a deflation tube in at least one of the at least two arms;

compromising a portion of a surface of the implant such that an inflation substance within the implant can escape;

removing the inflation substance out of the implant through the deflation tube in at least one of the at least two arms used to capture the implant, the deflating tube having a distal opening positioned in or near the portion of the surface that has been compromised; and

removing the implant together with the removal device from the anatomical structure.

2. The method of claim 1, wherein removing the inflation substance further comprises compressing the implant to evacuate the inflation substance out of the implant.

3. The method of claim 2, wherein compressing the implant comprises squeezing the implant between the at least two arms of the removal device.

4. The method of claim 2, wherein compressing the implant comprises pushing the implant against the bladder wall.

5. The method of claim 2, wherein compressing the implant comprises retracting the implant into a cannula.

6. The method of claim 1, wherein removing the inflation substance further comprises evacuating the inflation substance out of the implant with suction through the deflation tube.

7. The method of claim 1, wherein removing the inflation substance further comprises expelling the inflation substance into a bladder.

8. The method of claim 1, wherein compromising a portion of the surface of the implant comprises destroying the integrity of the portion of the implant with the application of force, heat, cryogenic energy, light, radiation, energy, pressure, ultrasonic pulse or a chemical.

9. The method of claim 1, wherein compromising a portion of the surface of the implant comprises advancing a sharp tip on the distal opening of the deflation tube through the surface of the implant.

10. The method of claim 1, wherein capturing the implant with all of the at least two arms of the removal device comprises engaging the implant with two opposing arms of the removal device.

11. The method of claim 1, wherein locating the implant within the anatomical structure further comprises locating the implant anchored to a surface of a bladder.

12. The method of claim 1, wherein locating the implant within the anatomical structure further comprises locating a floating implant within a bladder.

13. A method of removing a balloon from the bladder, the balloon having been previously implanted within the bladder, the method comprising:

locating the balloon within the bladder, the balloon being in an inflated condition;

advancing a retrieval device with two opposing arms within a single lumen;

capturing the balloon with the two opposing arms of the retrieval device;

compromising an outside surface of the balloon with a needle-like prong extending from at least one of the two opposing arms;

deflating the balloon with the needle-like prong; and

removing the balloon from the bladder.

14. The method of claim 13, wherein deflating the balloon with the needle-like prong further comprises vacuuming out the contents of the balloon through the needle-like prong.

15. The method of claim 13, wherein deflating the balloon further comprises compressing the balloon between the two arms of the removal device.

16. The method of claim 13, wherein deflating the balloon further comprises compressing the balloon against the wall of the bladder.

17. The method of claim 13, further comprising pulling the balloon into a cannula after initiating the step of deflating.

18. The method of claim 13, wherein the balloon is anchored to a surface of the bladder.

19. The method of claim 13, wherein locating comprises locating the balloon with a cystoscope.

20. The method of claim 13, wherein locating comprises locating a floating balloon within the bladder.
