Provided is an electrotherapy device suitably used in electroporation method, and specifically configured to inject medicine and the like into deep inside of the body. The electrotherapy device has an outer shaft having a lumen and extending in a distal-proximal direction; an inner shaft disposed in the lumen of the outer shaft; a needle tube fixed to the inner shaft; and at least one linear conductor having at least one electrode needle fixed to the inner shaft and having at least one conductive line connected to a proximal part of the electrode needle, the needle tube and the electrode needle configured to project or retract from a distal part of the outer shaft.

Electrotherapy device

In order to provide a catheter which can be operated even when it is deformed inside a bent blood vessel and whose movable part can be easily bent and the movable part thus bent is firmly kept in this shape, a catheter includes: a fluid-driven actuator including: a balloon; a restricting member for restricting inflation of the balloon in a short axis direction of the catheter; and a tube which is less stretchable in a long axis direction of the catheter than the balloon is, according to a cross-sectional view of the fluid-driven actuator taken along the short axis direction of the catheter, the tube being eccentrically provided with respect to the restricting member.
