Abstract

An implantable medical device is detailed that includes a housing enclosing an electronic circuit and source of power, and an optical unit sealingly coupled to the housing, the optical unit including a monolithic block made of a transparent ceramic material and comprising: a thin window defined by an inner surface and an outer surface, an outer mating structure for coupling a fiber optic to the monolithic block, and an inner mating structure for permanently coupling a light unit, and a light unit rigidly mounted in the inner mating structure of the monolithic block. The light unit includes a light element including one or more of an inner light source, and/or a photodetector, the light element and a fiber optic engaged in the outer mating structure are in alignment with a corresponding reference point located on the thin window.
