Abstract
An implantable active medical device system includes an active medical device and a lead extending between a proximal portion electrically coupled to the active medical device and a distal end portion configured to emit light. The distal end portion includes a solid state light source disposed within a light transmissive ring element. The light transmissive ring element forms an exterior segment of the distal end portion. The light transmissive ring element defines at least a portion of a hermetic cavity.
Claims17
An implantable active medical device system comprising:
- an active medical device;
- a lead extending between a proximal portion electrically coupled to the active medical device and a distal end portion configured to emit light, the distal end portion comprising:
- a solid state light source disposed within a light transmissive ring element, the light transmissive ring element forming an exterior segment of the distal end portion, the light transmissive ring element defining at least a portion of a hermetic cavity;
- and
- an optically coupling fluid that fills open space in the hermetic cavity wherein the optically coupling fluid substantially matches the index of refraction of the light transmissive ring element.
