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. |
