  • Publication number: 20180078761
    Abstract: A method including chronically implanting a nerve cuff electrode on a portion of a hypoglossal nerve, chronically implanting a respiration sensing lead subcutaneously in a thorax of a patient, the respiration sensing lead having a plurality of bio-impedance electrodes defining at least one bio-impedance vector. The method may also include sensing a bio-impedance signal corresponding to respiration via a bio-impedance vector on an anterior side of the thorax, analyzing the bio-impedance signal to identify onsets of expiration, predicting an onset of a future expiratory phase, and delivering a stimulus to the portion of the hypoglossal nerve via the nerve cuff electrode, wherein the stimulus is delivered as a function of the bio-impedance signal; wherein stimulus delivery is initiated before the onset of the future expiratory phase and continued during an entire inspiratory phase, and wherein the method is performed without identifying an onset of an inspiratory phase.

  • Patent number: 9895074
    Abstract: Systems and related methods for analyzing data sensed from a device implanted in a patient, such as a cardiac pacing system. The system detects and evaluates electric signals within the patient that share a common event marker. By using algorithms and graphical presentation of the collected signals having common event markers, deviations in signals over time can be identified and evaluated in consideration of taking further action related to the patient and the implanted device. The system can also be used in conjunction with an advanced patient management system that includes a programmer or repeater capable of gathering information from the implanted device and transmitting the data to a host via a communications network for evaluation at a remote location.

  • Publication number: 20160249817
    Abstract: A high performance guide wire with a pressure sensor for measuring blood pressure, may utilize a single electrical lead connected to the guide wire. An integrated circuit, powered by the single electrical connection on the guide wire, may interface with the pressure sensor, and may convert pressure information to an encoded signal. The encoded signal may be detectable in the electrical circuit, and can be used to display a pressure waveform as detected by the pressure sensor. For example, when utilized for percutaneous coronary interventions, such a guide wire can provide high quality blood pressure measurements (e.g., for fractional flow reserve), while also possessing excellent steerability and handling characteristics for navigating tortuous anatomy.
