Ureteral stent for placement in a kidney and bladder

A ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney, the ureteral stent comprising:

• a bladder coil having a first end, a second end, and a length extending therebetween, the bladder coil being free of a lumen extending along the length of the bladder coil between the first and second ends, the bladder coil being positionable in the bladder to prevent the bladder coil from migrating into the ureteral passageway, and the bladder coil including an eyelet formed at the second end extending in a direction perpendicular to a direction of the length of the stent;
• a tubular kidney member positionable in the kidney and the ureteral passageway, the tubular kidney member having a ureter portion configured to be positioned in the kidney and the ureteral passageway to place the ureteral passageway in an open state and a resilient fixing portion biased in an unrestrained position to secure the resilient fixing portion in the kidney;
• a first tether connecting the bladder coil and the ureter portion of the tubular kidney member to allow the bladder coil to float in the bladder and to allow a ureteral orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state, the first tether being coupled to the first end of the bladder coil;
• and
• a second tether extending through the eyelet for removing the ureteral stent from a patient.

A ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney, the ureteral stent comprising:

• a bladder coil having a conical first end, a second end, and a length extending therebetween, the bladder coil being free of a lumen extending along the length of the bladder coil between the conical first end and the second end;
• a tubular kidney member positionable in the kidney and the ureteral passageway;
• and
• a tether connecting the bladder coil and the tubular kidney member, the tether being non-removably coupled to the conical first end of the bladder coil.
