Abstract
Various embodiments of a hermetically-sealed package and a method of forming such package are disclosed. The package can include a housing having an inner surface and an outer surface, and a non-conductive substrate hermetically sealed to the housing. The package can also include a light source disposed on a first major surface of the substrate and adapted to emit light through the first and second major surfaces of the substrate, and a detector disposed on the first major surface of the substrate and adapted to detect the light emitted by the light source.
Claims20
A hermetically-sealed package, comprising:
- a housing comprising an inner surface and an outer surface;
- a non-conductive substrate hermetically sealed to the housing by a laser bond, wherein the substrate comprises a first major surface and a second major surface;
- a light source disposed on the first major surface of the substrate and adapted to emit light through the first and second major surfaces of the substrate;
- and
- a detector disposed on the first major surface of the substrate and adapted to detect the light emitted by the light source.
A method of forming a hermetically-sealed package, comprising:
- disposing a light source on a first major surface of a transparent substrate;
- disposing a detector on the first major surface of the transparent substrate;
- hermetically sealing the transparent substrate to the housing, wherein hermetically sealing the transparent substrate to the housing comprises laser bonding the first major surface of the substrate to the housing.
A method of detecting a physiological condition of a patient, comprising:
- disposing a hermetically-sealed package within a body of the patient, wherein the hermetically-sealed package comprises:
- a housing comprising an inner surface and an outer surface;
- a non-conductive substrate hermetically sealed to the housing by a laser bond, wherein the substrate comprises a first major surface and a second major surface;
- a light source disposed on the first major surface of the substrate;
- and
- a detector disposed on the first major surface of the substrate;
- directing light from the light source such that it is incident upon one or both of tissue and an artery of the patient;
- detecting a portion of the emitted light that is scattered by one or both of the tissue and the artery of the patient utilizing the detector;
- and
- determining the physiological condition of the patient based upon a characteristic of the detected light.
