Electromagnetic interference immune tissue invasive system
First Claim
Patent Images
1. An electromagnetic radiation immune sensing system, comprising:
- a photonic lead having a proximal end and a distal end;
a light source, 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;
a bio-sensor, in the distal end of said photonic lead, to measure changes in an electric field located outside a body, the electric field being generated by the shifting voltages on a body'"'"'s skin surface; and
a distal sensor, in the distal end of said photonic lead, to convert the first light into electrical energy and, responsive to said bio-sensor, 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 measured changes in the electric field.

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.
