Abstract: Devices and methods for treating obstructive sleep apnea by first performing an assessment of the patient that involves observing the patient's upper airway during a tongue protrusion maneuver. The assessment may, for example, be done using endoscopy to observe the upper airway while the patient is awake in the supine position. An adequate response of the upper airway during the tongue protrusion maneuver is indicative of likely therapeutic success with hypoglossal nerve stimulation, and may be used for making clinical decisions. The principles of the present invention may be applied to other therapeutic interventions for OSA involving the upper airway.

Abstract: Waveforms for a stimulator device, and methods and circuitry for generating them, are disclosed having high- and low-frequency aspects. The waveforms comprise a sequence of pulses issued at a low frequency which each pulse comprising first and second charge-balanced phases. One or both of the phases comprises a plurality a monophasic sub-phase pulses issued at a high frequency in which the sub-phase pulses are separated by gaps. The current during the gaps in a phase can be zero, or can comprise a non-zero current of the same polarity as the sub-phase pulses issued during that phase. The disclosed waveforms provide benefits of high frequency stimulation such as the promotion of paresthesia free, sub-threshold stimulation, but without drawbacks inherent in using high-frequency biphasic pulses.

Abstract: A system is disclosed in one example which allows for modelling the wellness of a given Implantable Pulse Generator (IPG) patient. The modelling, embodied in an algorithm, uses one or more qualitative measurements and one or more quantitative measurements taken from the patient. The algorithm correlates the qualitative measurements to the various quantitative measurements to eventually, over time, learn which quantitative measurements best correlate to the qualitative measurements provided by the patient. The algorithm can then using current quantitative measurements predict a wellness factor or score for the patient, which is preferably weighted to favor the quantitative measurements that best correlate to that patient's qualitative assessment of therapy effectiveness. Additionally, the wellness factor may be used to adjust the stimulation program that the IPG device provides to the patient.

Abstract: The present invention relates to a system and methods for noninvasively providing therapy for movement disorder symptoms. The present invention provides such a therapy system which provides trans-cranial direct current stimulation (tDCS) in order to treat those symptoms and the disorders. The present invention further provides such tDCS therapy while the subject sleeps in order to minimize the time required and impact of the therapy on the subject's waking life. The system, methods, and devices of the present invention are intended to provide a low-dose electrical current, trans-cranially, to a specific area of the subject's brain while he or she sleeps in order to decrease the occurrence, severity, and duration of the symptoms of movement disorders. The present invention aims to reduce the amount of medication necessary, counteract the effects of medication wearing off during sleep, and to overall improve the quality of life of subjects suffering from movement disorders.

Abstract: Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration.

Abstract: A neurostimulation system (NS) includes an array of electrodes positioned within a patient with an active cathode electrode located proximate to target neural tissue. A control circuit is controls delivery of therapy during a therapy delivery interval, with the therapy being delivered between an anode electrode and the active electrode. A current regulator circuit (CRC) is connected to the cathode electrode and controls current flow through the cathode electrodes. The control circuit manages the CRC to control a discharge current flow over the discharge operation to discharge developed residual voltage between the anode electrode and the active electrode in a manner that follows an actively emulated passive discharge (AEPD) profile. During the discharge operation, the CRC is connected to the inactive electrode, and receives, as a first input, an EMI feedback signal.
