Abstract
An example implantable medical device includes a housing comprising an optical window; an optical sensor within the housing and configured to emit light to the optical window; and a masking on a portion of the optical window, the masking configured to absorb a portion of the emitted light internally reflected within the optical window.
Claims20
An implantable medical device comprising:
- a housing comprising an optical window;
- an optical sensor within the housing and configured to emit light to the optical window;
- and
- a masking on a portion of the optical window, the masking configured to absorb a portion of the emitted light internally reflected within the optical window.

A method of determining a physiological characteristic of a patient, the method comprising:
- emitting light, by a light source of an optical sensor positioned in an implantable medical device (IMD), to an optical window of the IMD and towards a tissue of the patient, the light including optical sensing light that is to interact with the tissue of the patient and reflected light that is to be reflected in the IMD;
- blocking, by masking positioned on a portion of the optical window, at least a portion of the reflected light in the IMD;
- detecting, by a detector, the optical sensing light;
- and
- determining, by processing circuitry and based, at least, on the detected optical sensing light, the physiological characteristic of the patient.
