Abstract: A stimulation system for delivery of a stimulation signal to a hypoglossal nerve of a patient to treat obstructive sleep apnea. The stimulation system includes an implantable receiver coil configured to be implanted under a mandible of the patient; a nerve electrode coupled to the implantable receiver coil, the nerve electrode configured to deliver the stimulation signal to the hypoglossal nerve of the patient; an external pulse generator configured to generate the stimulation signal; and an external transmitter coil configured to wirelessly transmit the stimulation signal from the external pulse generator to the implantable receiver coil, the external transmitter coil being carried by an adhesive patch configured to be placed on the skin adjacent the implantable receiver coil under the mandible of the patient.

Abstract: An implantable neurostimulation system comprises a stimulation delivery lead and a neurostimulator. The stimulation delivery lead is coupled to an electrode. The neurostimulator is adapted to deliver a neurostimulation signal to the subject and comprises a microprocessor. The microprocessor is programmed to identify a stimulation operating window for the therapy including a first threshold and a second threshold. The second threshold comprises an awake level and an asleep level. Identifying the stimulation operating window comprises titrating a stimulation setting of the neurostimulator while the subject is awake until the first threshold and the awake level of the second threshold are identified. Identifying the stimulation operating window further comprises subsequently repeating the step of titrating the stimulation setting of the neurostimulator while the subject is asleep until the asleep level of the second threshold is identified.

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.

Abstract: Devices, systems, and methods are described by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably a baroreceptor located in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements/consumption. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.

Abstract: The present system is directed in various embodiments to methods, devices and systems for sensing, measuring and evaluating compliance in a bodily conduit. In other embodiments, the methods, devices and systems sense, measure, determine, display and/or interpret compliance in a bodily conduit and/or a lesion within the bodily conduit. In all embodiments, the sensing, measuring, determining, displaying and/or interpreting may occur before, during and/or after a procedure performed within the bodily conduit. An exemplary conduit comprises a blood vessel and an exemplary procedure comprises a vascular procedure such as atherectomy, angioplasty, stent placement and/or biovascular scaffolding.
