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