Abstract: This invention is a ureteral stent (100) for assisting movement of urine along a patient's ureter and into the patient's bladder. The stent (100) includes an elongated tubular segment (130) extending toward the bladder from a kidney end region for placement in the renal cavity to a bladder end region. A central lumen (260) connects at least one opening (127) at the first end region to at least one opening in the bladder end region. At least one flexible tail (110) is attached to the bladder end region of the tubular segment (130) at a point outside the bladder so as to receive urine from the opening in the bladder end region of the tubular segment (130) and to transport urine from there across the ureter/bladder junction and into the bladder. The tail (110) includes an elongated external urine transport surface sized and configured to transport urine along the ureter. The urine transporting surface is sized and configured to extend along at least part of the ureter, across the ureter/bladder junction, and from there into the bladder.

Abstract translation: 本发明是一种输尿管支架（100），用于辅助尿液沿着患者输尿管运动并进入患者膀胱。 支架（100）包括从肾端部区域向膀胱延伸的细长管状区段（130），用于放置在肾腔中至膀胱端部区域。 中心腔（260）将第一端部区域处的至少一个开口（127）连接到膀胱端部区域中的至少一个开口。 至少一个柔性尾部（110）在囊状物外部的点处附接到管状区段（130）的膀胱端部区域，以便从管状区段（130）的膀胱端部区域中的开口接收尿液，并且 从那里输尿管输尿管/膀胱交界处并进入膀胱。 尾部（110）包括细长的外部尿液输送表面，其大小和构造成沿着输尿管输送尿液。 尿液输送表面的尺寸和构造尺寸沿着输尿管的至少一部分延伸穿过输尿管/膀胱结，并从那里进入膀胱。
