Abstract
Provided is a ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney. The ureteral stent includes a solid bladder portion free of a lumen positionable in the bladder, a tubular kidney portion positionable in the kidney and the ureteral passageway, and a tether connecting the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state. By not having a lumen, the solid bladder portion allows the bladder to have a smaller diameter while maintaining a necessary uncoil force. The smaller diameter also allows the bladder portion to be inserted into a scope alongside a pusher tube, thereby avoiding loading the bladder portion onto a guidewire.
