An assistance method for assisting a person in grasping or otherwise manipulating an object includes receiving video of a hand of the person and of an object. An intent to grasp the object is identified based on proximity of the hand to the object in the video or as measured by a proximity sensor, or using gaze tracking, or based on measured neural activity of the person. The object and the hand in the video are analyzed to determine an object grasping action for grasping or otherwise manipulating the object. An actuator is controlled to cause the hand to perform the determined hand action for grasping or otherwise manipulating the object.

A method and apparatus for treatment of hypertension and heart failure by increasing vagal tone and secretion of endogenous atrial hormones by excitory pacing of the heart atria. Atrial pacing is done during the ventricular refractory period resulting in atrial contraction against closed AV valves, and atrial contraction rate that is higher than the ventricular contraction rate. Pacing results in the increased atrial wall stress. An implantable device is used to monitor ECG and pace the atria in a nonphysiologic manner.

A system for electrical ventilation stimulation of a patient including an implantable nerve stimulator including a stimulation circuit and a pulse generator that produces biphasic charge-balanced pulses to stimulate a phrenic nerve, an external digital programming device having near field communication transmission and a digital interface, and wherein the external digital programming device is used to control settings of the implantable nerve stimulator.

This document discusses, among other things, systems and methods to generate a first pacing waveform during a first pacing period and a second pacing waveform during a second pacing period, to alternate first and second pacing periods to provide pacing-based hypertension therapy to a heart of a patient to reduce patient blood pressure, to receive information indicative of patient metabolic demand, and to determine an adjusted pacing-based hypertension therapy parameter using the received information indicative of patient metabolic demand, wherein the first pacing waveform has a first atrioventricular (AV) delay and the second pacing waveform has a second AV delay longer than the first AV delay.

Systems including intra-calvarial implants and/or subdermal implants are capable of stimulating cortical regions and sensing and electrical signals is implanted within or on a calvarial bone of a skull. The implants have current steering capability to change the current density profiles applied to selected cortical regions underlying the implant. The systems may track changes in the position and/or spatial parameters of a neural network by recording cortical electrical signals and processing them to compute the values of one or more network activity biomarkers. The systems may spatially track changes detected in network anatomical position and deliver the stimulation of the cortex to the network detected position by using current steering methods.

Universal switch modules, universal switches, and methods of using the same are disclosed, including methods of preparing an individual to interface with an electronic device or software. For example, a method is disclosed that can include measuring brain-related signals of the individual to obtain a first sensed brain-related signal when the individual generates a task-irrelevant thought. The method can include transmitting the first sensed brain-related signal to a processing unit. The method can include associating the task-irrelevant thought and the first sensed brain-related signal with N input commands. The method can include compiling the task-irrelevant thought, the first sensed brain-related signal, and the N input commands to an electronic database.

A system and methods of maintaining communication with a medical device for exchange of information, instructions, and programs, in a highly reliable manner. Apparatus and methods for accomplishing this task include: 1) The inclusion of a locating device in the system, in close proximity to an implanted device, but which does not drain the implanted device battery. 2) The use of motion detection and global positioning system devices to locate elements within a communicating system for the medical device; 3) The assessment of received signal quality by elements of the system; 4) The use of a notification system for a device user who is moving out of range of communications; and 5) Documenting the absolute and functional integrity of instructions received by the medical device. A method of assuring the identification of communication participants is presented.

A neurostimulation system comprises a control system configured to monitor a patient receiving neurostimulation therapy. The neurostimulation therapy has a stimulation cycle comprising a stimulation ON period, in which the patient is receiving neurostimulation, and a stimulation OFF period, in which the patient is not receiving neurostimulation. The control system is programmed to receive electrocardiogram (ECG) data from the patient receiving the neurostimulation therapy. The control system is further programmed to monitor a heart rate of the patient based on the ECG data over at least one stimulation cycle of the neurostimulation therapy. The control system is further programmed to generate an indication of signal stability to be displayed to a user based on the received ECG data.

An implantable medical device (IMD) has a housing enclosing an electronic circuit. The housing includes a first housing portion, a second housing portion and a joint coupling the first housing portion to the second housing portion. A polymer seal is positioned in the joint in various embodiments. Other embodiments of an IMD housing are disclosed.

The present invention relates to a neuromodulation apparatus and methods of using the neuromodulation apparatus for treating bladder dysfunction.
