Anastomosis device and related methods
First Claim
1. A method of performing urethral anastomosis, the method comprisinginserting a portion of an anastomosis device into a urethra through a meatus, the anastomosis device comprising a distal end comprising a balloon and elongate tissue approximating structure located on a proximal side of the balloon,inflating the balloon in the bladder, andusing the tissue approximating structure to hold severed tissue together during healing,wherein the tissue approximating structure comprises multiple tines.

Abstract
Described are methods and devices relating to reconnecting the urethra and bladder after a radical prostatectomy, wherein the devices incorporate tissue approximating structure to maintain contact between a severed bladder neck tissue and a severed urethral stump tissue, preferably without the use of sutures.

19. A method of performing urethral anastomosis, the method comprising
inserting a portion of an anastomosis device into a urethra through a meatus, the anastomosis device comprising a distal end comprising a drainage aperture, the drainage aperture connected to a proximal end of the device by a drainage lumen, and elongate tissue approximating structure on a proximal side of the drainage aperture, inserting the drainage aperture in the bladder, using the tissue approximating structure to hold severed tissue together during healing, and draining the bladder through the drainage lumen, wherein the elongate tissue approximating structure on a proximal side of the drainage aperture comprises distal tissue approximating structure and proximal tissue approximating structure at fixed locations, the fixed locations being fixed relative to the distal end of the device and relative to a proximal end of the device.
-
26. A method of performing urethral anastomosis, the method comprising
inserting a portion of an anastomosis device into a urethra through a meatus, the anastomosis device comprising a distal end comprising first tissue approximating structure and elongate second tissue approximating structure, and extending the first tissue approximating structure within the bladder, and using the elongate second tissue approximating structure to hold severed tissue together during healing wherein the first tissue approximating structure is selected from the group consisting of a balloon and a balloon-like structure, the elongate second tissue approximating structure comprises a distal tissue approximating structure and a proximal tissue approximating structure, and the first tissue approximating structure and the second tissue approximating structure are at fixed locations, the fixed locations being fixed relative to the distal end of the device and relative to a proximal end of the device.
