Ureteral stent for improved patient comfort

摘要

A ureteral stent for assisting the 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 of the tubular segment and to transport urine from there across the ureter/bladder junction and into the bladder.

主权项

1. A ureteral stent, comprising:
a tubular body defining a lumen, the tubular body being of a length that extends from a kidney of a patient to a portion of a ureter between a bladder of the patient and the kidney such that a proximal end of the tubular body terminates in the portion of the ureter between the bladder and the kidney, a distal region of the tubular body including a retention structure configured to help retain the ureteral stent within the kidney; and at least one filament extending from the proximal end of the tubular body, the at least one filament being of a length that extends from the portion of the ureter between the bladder and the kidney to a location within the bladder, wherein the at least one filament is configured to transfer fluid received from the proximal end of the tubular body to the bladder along a surface of the at least one filament.
