Abstract
A stent delivery system for use in placing a stent within the prostatic urethra and ensuring that the stent does not interfere with the closure of the bladder neck sphincter. The delivery system includes a catheter with an anchor which anchors the catheter within the urethra and ensures placement of the stent at a predetermined distance from the bladder neck sphincter. For use with shape memory stents, the catheter includes a warming fluid system in which the endoscope used in the procedure can act as a fluid supply line and as valve spool to control the flow or warming fluid to the stent.
