ABSTRACT:
A ureteral stent for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent includes an elongated tubular segment extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen connects at least one opening at the first end region to at least one opening in the bladder end region. Thin flexible tail(s) are attached to the bladder end region of the tubular segment at a point outside the bladder so as to receive urine from the opening in the bladder end region and to transport urine from there across the ureter/bladder junction and into the bladder. The tails include an elongated external urine-transport surface configured to transport urine. The transporting surface(s) are configured to extend along at least part of the ureter, across the ureter/bladder junction, and into the bladder.
