ABSTRACT:
A ureteral stent comprising an elongated member having a proximal end portion and a distal end portion joined by a body portion. The elongated member has an initial outer diameter. A retention construction serves for retaining the member within the ureter. The member is formulated of a physiologically acceptable polymer capable of hydrating and expanding from the initial member outer diameter to form a final member outer diameter. The stent can assume differing shapes and can exhibit different degrees of softening at different places along its length.
