発明の名称 (英語) VENTRICULAR ASSISTANCE DEVICE
発明の概要(英語) The present invention is a ventricular assistance device provided with an internal implant-type pumping system, the device using a simple configuration in which one magnetic member (33a) is secured to a piston (32a) and the piston (32a) is made to travel in reciprocating motion by means of repulsive force and attractive force arising between a pair of magnetic members (33a, 35a). The foregoing configuration makes it possible, compared to conventional small electric motors, to inflate or deflate a balloon (20a) in a highly responsive and reliable manner without producing a time lag between a piston pump (30a) and the balloon (20a).
