Abstract:
1. An sensor unit configured to position a sensing element for monitoring a physiological parameter within a cavity of a living body, the sensor unit comprising: an anchor comprising: a sensing device comprising a hermetically-sealed housing that has an outer cross-sectional shape, a proximal end, and an oppositely-disposed distal end at which the sensing element is disposed, the housing containing processing circuitry electrically coupled to the sensing element; and a telemetry antennae adapted to communicate with the processing circuitry within the housing of the sensing device; wherein the opening in the shank portion of the anchor has a cross-sectional shape that is complementary to the outer cross-sectional shape of the housing of the sensing device, the housing is assembled with the anchor through the opening in the shank portion so that at least the proximal end of the housing is within the bore of the anchor, the distal end of the housing is exposed by the opening of the bore, the housing closes the opening in the bore to prevent biological matter from entering the bore, and the sensing element is exposed by the opening of the bore to sense the physiological parameter.
