发明名称 METHOD FOR REMOVING KIDNEY STONES
摘要 A method for removing a kidney stone from a ureter may involve: advancing a distal end of an elongate, flexible kidney stone removal device into the ureter to a location near the kidney stone; advancing an expandable stone retention member out of an inner shaft of the device; visualizing at least part of the stone retention member with a camera disposed coaxially within the stone retention member; trapping the kidney stone in the stone retention member; surrounding at least a portion of the stone retention member and the trapped kidney stone with a wall protection member on the distal end of the kidney stone removal device; and removing the kidney stone removal device from the ureter while the stone retention member and the kidney stone are at least partially surrounded by the wall protection member.

主权项 1. A method for removing a kidney stone from a ureter, the method comprising: advancing a distal end of an elongate, flexible kidney stone removal device into the ureter to a location near the kidney stone; exposing an expandable, stone retention portion of a stone retention member out of a distal end of an inner shaft of the stone removal device, to allow the stone retention portion to expand; visualizing at least part of the stone retention member with a camera disposed coaxially within a retention member shaft of the stone retention member so that a distal end of the camera is located at or near a distal end of the inner shaft; trapping the kidney stone in the stone retention portion of the stone retention member; surrounding at least a portion of the stone retention member and the trapped kidney stone with a ureteral wall protection member disposed on the distal end of the kidney stone removal device, wherein a first end of the wall protection member is attached to an outer shaft of the device and a second end of the wall protection member is attached to a wall protection member shaft disposed between the inner and outer shafts; and removing the kidney stone removal device from the ureter while the stone retention member and the kidney stone are at least partially surrounded by the wall protection member.
