Abstract: The disclosure provides systems and methods for detecting, monitoring, and/or treating obstructive sleep apnea, as well as other conditions, using vital sign and/or biometric data collected and/or imputed from one or more photoplethysmography sensors in conjunction with vital sign and/or biometric data from one or more additional sensors such as activity, body position, ECG, HR, or SpO2 levels, e.g., as feedback to control therapy and/or to titrate therapy on a periodic basis.

Abstract: The present disclosure relates to systems and methods for therapeutic nerve stimulation, particularly systems based on vibratory stimulation. Vibratory stimulation offers multiple advantages over other minimally or non-invasive neuromodulation techniques. In some aspects, the disclosure provides minimally invasive neuromodulation devices that can deliver stimulation when placed on the skin, as well as configurations that utilize percutaneous structures that extend into the body below the surface of the skin to transfer vibrational energy into the body.

Abstract: A method of treating obstructive sleep apnea in a patient includes measuring, with electrodes, thoracic impedance of the patient, and stimulating, with a nerve stimulation device implanted in the patient, a nerve of patient based on the thoracic impedance. The nerve is associated with sleep apnea, such as the hypoglossal nerve and/or the ansa cervicalis nerve. The electrodes may be either surface electrodes or implanted electrodes, and the thoracic impedance may be trans-thoracic impedance or intra-thoracic impedance.

Abstract: The disclosure provides systems and methods for treating sleep-disordered breathing (e.g., obstructive sleep apnea) using a system comprising an inertial measurement unit (IMU) which includes an accelerometer and/or a gyroscope, wherein the IMU is configured to detect movement by a human subject and to generate data based on the detected movement. Positional and/or movement data generated by the IMU is used by a stimulation system to detect gross movement by the subject, and to deliver electrical stimulation to a nerve which innervates an upper airway muscle (e.g., a hypoglossal nerve) in response to the detection of gross movement, in order to treat the subject.

Abstract: A stimulation system configured to be implanted in a patient includes an implantable pulse generator (IPG) and an implantable lead system. The IPG includes a processor, a memory device, a power supply, and an inertial sensing unit configured to measure one or more physiological indicators of the patient. The implantable lead system includes at least one electrical lead coupled to the power supply and at least one electrode at a distal end of the electrical lead. The memory device includes instructions that cause the IPG to receive the physiological indicators within an initial range; increase the initial range to an enlarged range in response to the physiological indicators crossing a threshold maximum value or a threshold minimum value of the initial range; receive the physiological signals within the enlarged range, analyze the physiological indicators, and deliver stimulation to the patient through the electrode in response to the physiological indicators.

Abstract: The present disclosure generally relates to systems and methods for a stimulation system. Various aspects of the present disclosure relate generally to the treatment of epilepsy, depression and/or other conditions in a subject using a nerve stimulator and, more particularly, to an effective and quicker titration method for selection of stimulation parameters of the nerve stimulator using biological markers that indicate potential therapeutic effects. Some aspects of the present disclosure may utilize a pupillometry sensor synchronized with the VNS stimulation system to compare pupil size of a subject with stimulation on and off and for obtaining filtered pupil response measurements after stimulating each electrode while modulating the stimulation parameters. Thus, aspects of the present disclosure allow for quicker titration of programmable stimulation parameters (e.g.

Abstract: The disclosure provides systems and methods for automatically titrating an electrical pulse amplitude for a patient-implanted VNS stimulator. One or more external sensors (e.g., EEG, EKG, EMG, auditory sensors, inertial motion sensors, etc.) can be applied to the patient to generate data relevant to an acceptable amplitude of the electrical pulse for a given cathode in a multi-cathode cuff. In one embodiment, the device may include a controller on the implanted VNS stimulator that receives data, e.g., using a wireless connection, from the external sensors and titrates upward the amplitude until an acceptable amplitude is determine that provides efficacy with minimal, if any, side effects.

Abstract: Polymer materials are useful as electrode array bodies for neural stimulation. They are particularly useful for retinal stimulation to create artificial vision, cochlear stimulation to create artificial hearing, or cortical stimulation many purposes. The pressure applied against the retina, or other neural tissue, by an electrode array is critical. Too little pressure causes increased electrical resistance, along with electric field dispersion. Too much pressure may block blood flow. Common flexible circuit fabrication techniques generally require that a flexible circuit electrode array be made flat. Since neural tissue is almost never flat, a flat array will necessarily apply uneven pressure. Further, the edges of a flexible circuit polymer array may be sharp and cut the delicate neural tissue. By applying the right amount of heat to a completed array, a curve can be induced.
