Abstract
The method disclosed may be used following a prostatectomy may comprise inserting an instrument having an end effector into the bladder lumen via the urethra; using the end effector to urge the bladder wall to the pelvic floor and drive an anchor through the bladder wall into the pelvic floor, thereby connecting a balloon harness within the bladder to the pelvic floor; withdrawing the end effector; inserting and inflating a balloon catheter within the balloon harness, thereby pressing the bladder wall surrounding the bladder opening against the pelvic floor; maintaining the balloon catheter in place and draining the bladder during the time required for the tissues to effectively knit; and then deflating and withdrawing the balloon catheter and disconnecting and withdrawing the balloon harness. The instrument may comprise one or more tubes that support an end effector comprising a positioner and an anchor driver.
