The second portion has a larger diameter than the first portion and receives the straight section therein which is bonded thereton. The end of the straight section within the second portion forms a shoulder for abutment by an injection catheter to inject the stent into a patient. The outer surface of the distal portion is relatively soft to avoid bladder irritation.
