This application is generally related to systems and methods for providing a medical therapy to a patient by tracking patient activity and adjusting medical therapy based on occurrence of different types of activities performed by the patient while automatically rescheduling stimulation programs based on detected patient activity.

The present disclosure provides a device for state-dependent pudendal nerve stimulation for bladder control in a subject and methods of making and using the same.

An example of a system for delivering neurostimulation may include a programming control circuit and a user interface. The programming control circuit may be configured to generate stimulation parameters controlling delivery of the neurostimulation according to a pulse sequence. The pulse sequence may include a series of neurostimulation pulses and be defined by sequence parameters and one or more modulation functions each modulating an adjustable parameter selected from the sequence parameters. The user interface may be configured to set the pulse sequence to a tonic pulse sequence by determining an initial value for each adjustable parameter and set the pulse sequence to a modulated pulse sequence by selecting one or more adjustable parameters, determining a modulation function for each selected adjustable parameter, and applying the determined modulation function to that selected adjustable parameter to modulate the tonic pulse sequence.

Systems and methods for applying electrical stimulation to different sub-populations of targeted neurological tissue for optimizing spinal cord stimulation are disclosed. According to an aspect, a method includes applying a first pattern of electrical stimulation to a first sub-population of targeted neurological tissue of a subject. The method also includes applying a second pattern of electrical stimulation to a second sub-population of targeted neurological tissue of the subject, the second pattern of electrical stimulation being applied at a different frequency than the first pattern of electrical stimulation.

A method for controlling synchrony in a plurality of brain regions of a subject includes receiving signals from a source region of the subject's brain, determining at least one phase of the signals from the source region in a predetermined frequency band and delivering at least one stimulation pulse to at least one target region of the subjects brain based on the at least one phase of the signals from the source region to synchronize oscillations of the source region and the at least one target region.

A system for stimulating a sympathetic chain includes an electrode assembly that is configured to attach to a bone in proximity to a targeted portion of the sympathetic chain. The electrode assembly includes a cathode and an anode. The system also includes a power supply connected to the electrode assembly and configured to deliver power to the electrode assembly. The electrode assembly generates an electrical field between the cathode and the anode when power is delivered to the electrode assembly. The electrical field reaches the targeted portion of the sympathetic chain to provide electrical stimulation to the targeted portion of the sympathetic chain.

A system and method for extracting ETI load parametric data relative to one or more electrodes of an implanted stimulation lead system associated with an IPG. A Kelvin connection scheme is provided for measuring induced voltages present at stimulated electrodes during a stimulation ramping sequence, which may be used for determining the ETI parametric data using a number of techniques, including, without limitation, a waveform analysis.

Systems and methods for treating and/or averting cardiac arrhythmias, such as atrial fibrillation, are provided. A device comprises a housing including an energy source, a contact surface and an electrode. The energy source is configured to transmit an electrical impulse to the electrode through the outer skin surface to a vagus nerve of the patient. The electrical impulse comprises bursts of about 2 pulses to about 20 pulses with each of the bursts having a frequency of about 3 Hz to about 100 Hz. The electrical impulse modulates the vagus nerve to treat a cardiac arrhythmia of the patient. A system includes a sensor for detecting a physiological parameter of a patient's heart, such as heart rate variability, and a controller configured to activate the stimulator based on the physiological parameter to cause the stimulator to generate the electrical impulse.

A neuromodulation system, device, and method are disclosed. In an embodiment, a neuromodulation system includes a processor, a signal generator, a first electrode, and a second electrode. The processor in cooperation with the signal generator, the first electrode, and the second electrode are configured to deliver a transcutaneous stimulation to a mammal. The transcutaneous stimulation is configured by the processor for inducing voluntary movement in the mammal. The first electrode is positioned transcutaneously on a spinal cord and/or spinal cord dorsal roots of the mammal. Additionally, the second electrode is placed transcutaneously on or over at least one of the spinal cord and/or the spinal cord dorsal roots, a muscle, a nerve, or on or near a target end organ or bodily structure of the mammal. The second electrode is in communication with the first electrode through a hardwire or wireless connection.

A dental treatment apparatus is a dental treatment apparatus that energizes a dental treatment site such as a root canal with a high-frequency current. Included are a holder that holds an electrode placed at the dental treatment site, a power supply that energizes the electrode with the high-frequency current, and control circuitry that causes, during the energization operation, the power supply to provide stop period where the energization of the electrode with the high-frequency current is stopped between single energization period and next single energization period.
