An object of the present invention is to prevent a medical device such as an injection needle from being harmfully damaged when delivered to or withdrawn from a body anatomy. The shaft includes a shaft having a passage extending the entire length thereof, and a distal end effector assembly extending from a distal end of the shaft, wherein the distal end effector assembly is made of a conductive material and has electrical energy. A cylindrical distal tool defining a lumen, a distal surface 1803 wider than the distal tool, and the distal tool extending through the lumen of the distal tool. A passage leading to a surface and in fluid communication with the passage of the shaft; and a passage opening to the distal surface and extending through the lumen of the distal tool to reach the distal surface. An opening 1802 communicating therewith. [Selection] FIG. 13A |
