    摘要： Implantable medical devices and techniques are implemented that use bio-impedance to measure aspects of patient physiology. A signal separation method is performed at least in part in an implantable device. The method involves detecting a plurality of impedance signals using a plurality of implantable electrodes coupled to the implantable device. The method further involves separating one or more signals from the plurality of impedance signals using a signal separation technique, such as an algorithm-based separation technique.

    摘要： Methods and devices detect context related to a patient when monitoring a physiological condition of the patient and/or when applying one or more modes of therapy. The context may be a patient context such as posture or an environmental context such as ambient conditions. The context may be used in various ways in relation to the physiological measurement, such as to control when the physiological measurements are made, to appropriately flag physiological measurements, to be recorded in association with the physiological measurements, and/or to correct the physiological measurements based on a reference context. A device such as a beacon transmitter is used in detecting the context and a measurement device such as an implantable cardiovascular device is used to capture the physiological measurements.

    摘要： Devices, systems, and methods for monitoring and analyzing physiologic parameters within the body using an intrabody ultrasound signal are disclosed. An illustrative method includes receiving an ultrasound signal transmitted from a remote device containing encoded sensor data, converting the ultrasound signal into an electrical signal, decoding the sensor data from the electrical signal and generating a first physiological waveform, generating a second physiological waveform by analyzing fluctuations of the electrical signal caused by physiologic modulation of the ultrasound signal during propagation through the body, and analyzing one or more characteristics of the first and second waveforms to determine one or more physiologic parameters within the body.
