Device and method for deflation and removal of implantable and inflatable devices
First Claim
1. A method, comprising:
- pressing a distal end of a catheter against a wall of an inflated balloon of an implanted device such that the distal end creates a substantially normalized surface of the balloon; and
advancing a coring tip from a retracted position within the catheter to an extended position beyond the distal end of the catheter and into the balloon, wherein the coring tip removes a portion of the surface of the balloon to create a substantially circular cored opening through the substantially normalized surface of the balloon.

Abstract
Deflation devices 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 are disclosed herein. In one embodiment, the coring member comprises a handle disposed near the proximal end of the catheter, a cable, and a coring tip disposed near the distal end of the catheter. The distal end of the catheter can be configured to press against a wall of a balloon to create a substantially normalized surface of the balloon relative to a coring tip. A method for deflating and removing an implanted device, in accordance with another embodiment, can include pressing a distal end of a catheter against the wall of an inflated balloon of the device, and advancing the coring tip within the catheter beyond the distal end of the catheter and into the balloon.

14. A method comprising:
-
pressing a distal end of a catheter against a wall of an implanted gastric pressurized balloon, wherein a normalized surface of the wall is formed at a contact point between the distal end and the wall; advancing a hole making element from a retracted position within the catheter to an extended position beyond the distal end; and cutting a substantially circular hole in the wall of the balloon to remove a portion from the surface of the balloon. - View Dependent Claims (15, 16, 17)
