1. 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.

Abstract
An electromagnetic immune tissue invasive system includes a primary device housing. The primary device housing having a control circuit therein. A shielding is formed around the primary device housing to shield the primary device housing and any circuits therein from electromagnetic interference. A lead system transmits and receives signals between the primary device housing. The lead system is either a fiber optic system or an electrically shielded electrical lead system.
