Abstract
A ureteral drainage stent is designed to be placed in a patient's ureter and extend into a patient's bladder. An elongated tubular segment includes a distal region for placement in the renal cavity, and a proximal region for placement in a urinary bladder. A central lumen connects at least one opening in the distal region to at least one opening in the proximal region. The elongated segment is constructed such that the wall surrounding the lumen is thinner in the proximal region than in the distal region. The thin-walled portion of the elongated segment extends along at least part of the ureter, across the ureteral vesicle junction, and from there into the bladder.
