Abstract
An expandable ureteral stent placed in a patient's ureter so as to extend into the bladder of the patient. Expansion and contraction of the stent accommodates motion of the patient's kidney and bladder, gently holding the stent in position and reducing patient discomfort. The length of the stent is variable up to several centimeters.
