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