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.

A photonic lead system, comprising:
- a photonic lead having a distal end, a proximal end, and an optical communication channel between said distal end and said proximal end;
- a magnetic radiation coil, located in said distal end, to generate an electrical current corresponding to magnetic radiation characteristics of a predetermined nature;
- and
- a converter to convert said electrical signal generated by said magnetic radiation coil to an optical signal, said optical signal to be propagated along said optical communication channel from said distal end to said proximal end.

A photonic lead system comprising:
- a photonic lead having a distal end and a proximal end;
- a magnetic radiation coil, located in said distal end, to detect characteristics of magnetic radiation of a predetermined nature;
- an amplifier operatively connected to said magnetic coil;
- a control circuit, operatively connected to said amplifier, to produce control signals corresponding to the detected characteristics of the magnetic radiation;
- a light source, located in the proximal end of said photonic lead, to produce a first light having a first wavelength and a second light having a second wavelength;
- a wave-guide between the proximal end and distal end of said photonic lead;
- and
- a distal sensor, in the distal end of said photonic lead, to convert the first light into electrical energy and, responsive to said control signals, to reflect the second light back the proximal end of said photonic lead such that a characteristic of the second light is modulated to encode the detected characteristics of the magnetic radiation.
