A system for removing a kidney stone from a ureter, the system comprising: a handle including a shaft slider and a retention member slider; an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end connected to the shaft slider, such that the outer shaft slides with the shaft slider; a wall protection member shaft coaxially disposed within the outer shaft; a compliant ureter wall protection member, having a first end coupled with the distal end of the outer shaft and a second end coupled with a distal end of the wall protection member shaft; an elongate, flexible, inner shaft extending coaxially within at least part of the wall protection member shaft and having a proximal end fixedly attached to the handle, such that the inner shaft does not move relative to the handle; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft, wherein the stone retention member comprises: a retention member shaft having a proximal end attached to the retention member slider, such that the retention member shaft slides with the retention member slider; and a stone retention portion disposed at a distal end of the retention member shaft; and an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft, wherein the retention member shaft is free to slide proximally and distally over the camera and within the inner shaft. a handle including a shaft slider and a retention member slider; an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end connected to the shaft slider, such that the outer shaft slides with the shaft slider; a wall protection member shaft coaxially disposed within the outer shaft; a compliant ureter wall protection member, having a first end coupled with the distal end of the outer shaft and a second end coupled with a distal end of the wall protection member shaft; an elongate, flexible, inner shaft extending coaxially within at least part of the wall protection member shaft and having a proximal end fixedly attached to the handle, such that the inner shaft does not move relative to the handle; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft, wherein the stone retention member comprises: a retention member shaft having a proximal end attached to the retention member slider, such that the retention member shaft slides with the retention member slider; and a stone retention portion disposed at a distal end of the retention member shaft; and a retention member shaft having a proximal end attached to the retention member slider, such that the retention member shaft slides with the retention member slider; and a stone retention portion disposed at a distal end of the retention member shaft; and an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft, wherein the retention member shaft is free to slide proximally and distally over the camera and within the inner shaft.
