    摘要： An implantable sensor module and medical device includes a housing having an inner shell having a thickness extending between an inner wall and an outer wall and an outer layer, wherein the inner shell and the outer layer form a substantially flat portion. A shoulder extends adjacent to a diaphragm to extend the outer layer laterally away from a central medial line extending between edges of the diaphragm. A recess portion is formed between the diaphragm and an inner side of the outer layer, and an over-fill channel is formed by the outer layer extending through the outer layer from an opening formed at the outer wall to an opening formed along the inner side of the outer layer extending along the substantially flat portion.

    摘要： A first concentration of a chromophore corresponding to a measurement volume of an optical sensor is determined. A second concentration of the chromophore is obtained in the vicinity of the measurement volume corresponding to a change in at least one of a total concentration of the chromophore and a relative concentration of a first form of the chromophore to the total concentration of the chromophore in the measurement volume. Light remittance measurements including a first light wavelength and a second light wavelength are obtained corresponding to the first chromophore concentration and the second chromophore concentration. A coefficient for computing an index of a change in the chromophore concentration is computed using the difference between the first and second chromophore concentrations and the first and second light remittance measurements.

    摘要： A medical device for monitoring of oxygen saturation includes an optical sensor adapted for positioning adjacent to a tissue volume. The optical sensor has a light emitting portion capable of emitting light at a plurality of wavelengths and a light detecting portion capable of generating an electrical output signal corresponding to light incident on the detecting portion. A control module coupled to the optical sensor controls the light emitted by the light emitting portion. A monitoring module receives the output signal from the light detecting portion and computes a volume-independent measure of oxygen saturation in the volume of tissue using the output signal.

    摘要： Aspects of the present disclosure include a medical device system including an implantable medical device and an external device with three or more electrodes configured to contact a patient's skin. The external device either transmits or receives a test signal to or from the implantable medical device using a plurality of possible receive dipoles, where each possible receive dipole is formed by a pair of electrodes. A signal quality monitor, either at the implantable medical device or at the external device, measures a signal quality for the possible receive dipoles.
