Abstract:
1. An electromagnetic radiation immune tissue invasive 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; 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 sense characteristics of a predetermined tissue region; and a distal sensor, in the distal end of said photonic lead, to convert the first light into electrical energy; said distal sensor, responsive to said bio-sensor, causing a second light, the second light having a second wavelength, to be propagated, through said wave-guide, to the proximal end of said photonic lead such that a characteristic of the second light is modulated to encode the sensed characteristics of the predetermined tissue region; said light source, in the proximal end of said photonic lead, producing said second light having said second wavelength; said distal sensor, in the distal end of said photonic lead, reflecting the second light back to the proximal end of said photonic lead such that a characteristic of the second light is modulated to encode the sensed characteristics of the predetermined tissue region.
