Claim:
1. A method for removing a calculus located in a lumen of a ureter, the method comprising: moving a ureteral plug part of an elongated member in the lumen of the ureter toward the calculus located in the lumen of the ureter and past the calculus so that the ureteral plug part is positioned beyond the calculus, the ureteral plug part being positioned at a distal portion of the elongated member, the elongated member also including at least one irrigation port positioned between the ureteral plug part and a proximal end portion of the elongated member, the ureteral plug part being sized so that an outer surface of the ureteral plug part is spaced from an inner surface of the lumen in the ureter; occluding the lumen in the ureter while the ureteral plug part is positioned beyond the calculus by causing the outer surface of the ureteral plug part to contact the inner surface of the lumen in the ureter along less than a 360° circumferential extent; washing away the calculus in the ureter in a direction away from the ureteral plug part by discharging fluid from the irrigation port into the lumen and toward the calculus; releasing the occlusion of the lumen in the ureter; and withdrawing the elongated member, inclusive of the ureteral plug part lumen in the ureter, from the lumen of the ureter.
