Abstract: A device to measure tissue impedance comprises drive circuitry coupled to calibration circuitry, such that a calibration signal from the calibration circuitry corresponds to the current delivered through the tissue. Measurement circuitry can be coupled to measurement electrodes and the calibration circuitry, such that the tissue impedance can be determined in response to the measured calibration signal from the calibration circuitry and the measured tissue impedance signal from the measurement electrodes. Processor circuitry comprising a tangible medium can be configured to determine a complex tissue impedance in response to the calibration signal and the tissue impedance signal. The processor can be configured to select a frequency for the drive current, and the amount of drive current at increased frequencies may exceed a safety threshold for the drive current at lower frequencies.

Abstract: One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device (“IMD”), an external computing device, and a backend computing system. The IMD determines a physiologic parameter value within a patient's body, and communicates the physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device receives the physiologic parameter from the IMD and communicates it to the backend computing system. The backend computing system receives the physiologic parameter value and obtains an ambient condition value outside the body.

Abstract: One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device (“IMD”), an external computing device, and a backend computing system. The IMD determines an absolute physiologic parameter value within a patient's body, and communicates the absolute physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device receives the absolute physiologic parameter from the IMD and communicates it to the backend computing system. The backend computing system receives the absolute physiologic parameter value and obtains an ambient condition value outside the body that can affect the absolute physiologic parameter value.

The adherent device may comprise a unique adherent device identifier such that the customized alert can be sent based on the unique device identifier. Each of the gateways can be carried and may comprise a unique gateway identifier, such that the unique device identifier and the unique gateway identifier can be used to locate the ambulatory patient.

Abstract: Systems and methods provide for the selective prevention of data transfer from a medical device to allow the patient to have privacy when desired. These systems and methods provide medical devices that can be instructed to stop recording data and/or transmitting data to external devices and systems. These systems and methods also provide external repeater devices that can be instructed to stop recording data being received, stop forwarding data that is being or has already been received, and/or to stop soliciting data from the medical device. These systems and methods also provide for a blocking device that may be separate from the medical device and repeater to prevent data transfer such as by stopping the recording or transmission of data. The blocking device may be configured to provide a jamming signal to prevent data transmissions from being successfully communicated between the medical device and the repeater.
