1. An implantable cable desired for transmission of a signal to and from a body tissue of a vertebrate, comprising:
- a fiber optic bundle having a surface of non-immunogenic, physiologically compatible material, said fiber optic bundle being capable of being permanently implanted in a body cavity or subcutaneously, said fiber optic bundle having a distal end for implantation at or adjacent to the body tissue and a proximal end;
said proximal end being adapted to be coupled to and direct an optical signal source;
said distal end being adapted to be coupled to an optical stimulator;
said fiber optic bundle delivering an optical signal intended to cause an optical stimulator coupled to said distal end to deliver an excitatory stimulus to a selected body tissue, the stimulus being causing the selected body tissue to function as desired;
a photoresponsive device for converting the light transmitted by said fiber optic bundle into electrical energy, and for sensing variations in the light energy to produce control signals;
a charge accumulating device for receiving and storing the electrical energy produced by the photoresponsive device; and
a discharge control device, responsive to the control signals, for directing the stored electrical energy from the charge accumulating device to a cardiac assist device associated with a 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.
