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. |

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. |
