    摘要: A medical device system and associated method are used for monitoring tissue oxygenation. An optical sensor produces a signal corresponding to tissue light attenuation. A processor receives the optical sensor signal and computes a first measure of light attenuation at a first light wavelength and a second measure of light attenuation at a second light wavelength. In one embodiment, noise cancellation circuitry receives the first measure and the second measure and generates a guessed ratio of the first and second measures. Using the first measure, the second measure and the guessed ratio, the noise cancellation circuitry provides a peak output power when the guessed ratio corresponds to an actual ratio of the first and second measures.

    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.

    摘要: An implantable medical device system senses a first signal using a first acoustical sensor adapted to be operatively positioned in a first internal body location for sensing heart sounds in a patient. The system includes a second acoustical sensor adapted to be operatively positioned in a second internal body location for sensing sounds in the patient and generate a second signal that is less responsive to the heart sounds than the first acoustical signal. An implantable medical device including a housing and a processor enclosed in the housing receives the first signal and the second signal and generates a corrected first signal by canceling non-cardiac signals in the first signal using the second signal.
