Patent ID: 6845266

Claim:
A tissue invasive photonic 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 radiation scattering medium at the distal end of the photonic lead to receive radiation from said wave-guide; a plurality of power sensors to receive scattered radiation from said radiation scattering medium and convert the received scattered radiation into electrical energy; a bio-sensor, in the distal end of said photonic lead, to sense characteristics of a predetermined tissue region; and a distal emitter, in the distal end of said photonic lead and responsive to said bio-sensor, to emit a second light having a second wavelength to 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.
