Patent ID: 8231517

Claim:
An electromagnetic cardiac assembly adapted to assist ventricular output in a human heart comprising: a magnetic mat adapted for mounting inside a human body adjacent the heart, said mat being made from a material responsive to application of an electromagnetic field so as to be movable in a first direction into compressive relation with the heart in response to application of the electromagnetic field thereto and movable in a second direction out of said compressive relation to permit the heart to relax when application of said electromagnetic field is discontinued, said mat having a shaped, continuous posterior surface that substantially conforms to a shaped anterior surface of the heart for uniform conformity of the shaped posterior surface of the mat and the shaped anterior surface of the heart without flexing said mat when the mat is mounted adjacent the heart; and an electromagnetic subassembly adapted for mounting on the human body in functionally cooperative relation with respect to said mat, and for alternately generating and discontinuing said electromagnetic field so that said mat alternately moves into and out of said compressive relation with the heart.
