Abstract
A medical device capable of improving handling properties and maintaining excellent insulation properties of conductive wires for supplying electricity to electrodes for performing treatment includes: an elongated shaft part having a guide wire lumen formed therein, the guide wire lumen being open at a distal part; a plurality of electrodes which are disposed on the distal side of the shaft part, extend in the longitudinal direction of the shaft part, and are deformable in the radial direction of the shaft part; and a plurality of conductive wires which extend from the proximal side of the shaft part to the distal side thereof and transfer electricity to an electrode layer. The conductive wires extend inside the electrodes and outside the guide wire lumen, and are electrically connected to the electrodes at the distal side of the electrodes.
