    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.

    摘要： In one embodiment, the invention is directed to a ureteral stent adapted for placement within a patient's urinary tract to facilitate drainage from the patient's kidney to the patient's bladder. The ureteral stent includes an elongated portion, a retention portion and a mesh or coil portion. The elongated portion has first and second ends, defines an elongated portion of a lumen extending between the first and second ends, and has a length sufficient to extend within the ureter from the patient's kidney to the patient's bladder. The retention portion extends from the first end of the elongated portion, defines a retention portion of the lumen and at least one through aperture for providing fluid communication between the lumen and the kidney. The retention portion is adapted for placement substantially within the kidney and for retaining the placement of the stent within the kidney. The mesh or coil portion extends from the second end of the elongated portion and is adapted for placement substantially within an intramural tunnel portion of the ureter and for extension into the bladder. The mesh or coil portion is collapsible under radial compression to inhibit urine back flow to the kidney.

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. The tails include an elongated external urine-transport surface sized and configured to transport urine along the ureter. The urine transporting surface(s) are sized and configured to extend along at least part of the ureter, across the ureter/bladder junction, and from there into the bladder. In some embodiments, the distal region includes a tubular body with a lumen in fluid communication with an interstitial area defined by one or more flexible filaments of the proximal region forming at least one loop.
