Abstract:
1. A method for decompressing a ureteral stone in a ureter between a bladder and a kidney, said method comprising: providing a guide member including a proximal section, a distal section detachably connected to a distal end of the proximal section, and a deployable anchor near a distal end of the distal section; advancing the guide member from the bladder through the ureter past the ureteral stone; deploying the anchor on the guide member within the ureter distal to the stone, wherein the anchor does not extend into the kidney; engaging the anchor against a kidney side of the stone; detaching the proximal section of the guide member from the distal section after the anchor has been deployed; removing the detached proximal section of the guide member from the bladder; and leaving the distal section of the guide member in place to create a leakage path past the stone to drain urine, relieve pain, and reduce the risk of kidney damage while the stone remains in the ureter, wherein the distal section of the guide member does not extend into the kidney.
