摘要

PROBLEM TO BE SOLVED: To enable a lead to be easily implanted in curved subcutaneous part.

SOLUTION: A lead assembly includes a lead that is implanted in a living body and a lead manipulator with a long shape that moves the lead in order to adjust the implantation location. The lead comprises the following: a first lumen that communicates from the base end to a predetermined position; a second lumen that communicates from that predetermined position to the tip and has a smaller diameter than the first lumen; and a lead body on which is formed a locking unit at the boundary between the first lumen and the second lumen. The lead manipulator comprises the following: a manipulation unit with a long shape that can penetrate the second lumen; and a lock-engaging unit that connects to the manipulation unit and comes into contact with the locking unit in a state where the manipulation unit has passed through the first lumen in order to penetrate the second lumen.
