Abstract

An adjustable ureteral stent comprises an elongated, flexible tubular member with a hook at the proximal end, a generally straight elongated trimmable portion extending to the distal end and means for forming a hook at the distal end. In one embodiment the means is a second member which connects to the distal end of the first member and in another embodiment the means is a reinforcing wire or strip in the wall of the tubular member which when formed into a hook will retain that shape in the absence of a straightening force.
