摘要:
A ureteral stent is designed to be placed within a patients ureter to facilitate drainage from the patients kidneys to the bladder. An elongated portion of the stent includes a length sufficient to extend substantially within the ureter from the kidney to the bladder, and the elongated portion defines a lumen extending therethrough. A retention portion extends from one end of the elongated portion and retains the position of the ureteral stent when placed substantially within the kidney. The retention portion includes an interior space that is in communication with the lumen within the elongated portion and has at least one opening for urine drainage. A flared portion extending from the other end of the elongated portion is positioned within the patients bladder. The flared portion curves outward and includes an elastic member that maintains the shape of the flared portion when positioned within the bladder.
