Abstract:
A cardiac assist system, comprising:a primary device housing including a power supply and a light source; said primary device housing having a control circuit therein; a shielding formed around said primary device housing to shield said primary device housing and any circuits therein from electromagnetic interference; a cardiac assist device associated with a heart; a photonic lead system to transmit between said primary device housing and said cardiac assist device, both power and control signals in the form of light; a photoresponsive device to convert the light transmitted by said photonic lead system into electrical energy and to sense variations in the light energy to produce control signals; a charge accumulating device to receive and store the electrical energy produced by said photoresponsive device; and a discharge control device, responsive to the control signals, to direct the stored electrical energy from said charge accumulating device to said cardiac assist device associated with the heart.
