Patent ID: 8235884

Claim:
An electromagnetic cardiac assembly adapted to assist ventricular output in a human heart, the electromagnetic cardiac assembly comprising: a magnetic mat adapted for mounting inside a human body near 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; 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; an energy dispersion device made from a soft material, the energy dispersion device adapted for mounting between said mat and the heart so that the mat does not contact the heart, said energy dispersion device being constructed and arranged to disperse energy between said mat and the heart when the mat is moved into compressive relation with the heart so that the energy is gradually transferred and evenly distributed to the heart; a transducer for evaluating compressive resistance of the heart during movement of said mat into compressive relation with the heart and for generating an electrical signal as a function of said compressive resistance of the heart; and a control circuit constructed and arranged to receive said signal generated by said transducer and to control an intensity level of the electromagnetic field generated by said electromagnetic subassembly as a function of said signal to thereby control a degree to which said mat compresses the heart.
