発明の名称 (英語) VENTRICULAR ASSISTANCE DEVICE UPDATE
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).
従来技術、競合技術の概要(英語) BACKGROUND ART
The external wall of the heart compression, and allowed to relax, to assist in the ventricular function in the method known in the prior art. In particular, the balloon is installed outside of the heart wall surface, to introduce fluid into the balloon by inflating the balloon to compress the ventricle and the action of the balloon fluid is discharged from the balloon by the retraction of the ventricle relax the cardiac device to an auxiliary operation has been known (for example, see Patent Document 1).
In addition, are provided with an auxiliary heart, and the introduction of a fluid into the balloon to discharge the air with respect to the pumping system, as those can be installed into the body, a small electric motor is used with a piston-type pump system is disclosed (for example, see Patent Document 2).
