A stimulation probe device including a first electrode, a stimulation module, a control module and a physical layer module. The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

Wireless Stimulation Probe Device for Wireless Nerve Integrity Monitoring Systems

Various methods and devices for providing transdermal electrical stimulation therapy to a patient are provided. In certain variations, a method may include positioning a stimulator electrode over a glabrous skin surface overlying a target nerve of a subject. Electrical stimulation may be delivered through or across the glabrous skin surface to the target nerve to stimulate the target nerve, while remaining safe and tolerable to the patient. Electrical stimulation may be delivered at frequencies that may be painful or intolerable when applied over non-glabrous surfaces of the body. Various applicators or devices for providing transdermal electrical stimulation therapy are also provided.

Embodiments of the present invention describe a system and method of stimulating nerves during a medical procedure including positioning one or more electrodes in electrical contact with one or more nerves of a patient and electrically stimulating the one or more nerves during a lower urinary, rectal or medical procedure affecting the bowel sufficient to affect one or more of bladder activity, prostate function, incontinence, or pain.

Neuromodulation system and related methods

Disclosed is a system including a good comprising a sensor in contact with human tissues of a patient and configured to obtain a power dissipation reading of the human tissues. The good also includes a storage medium for tangibly storing thereon a program for execution by a processor. The system also includes a control unit in communication with the good to form an electrical muscular stimulation (EMS) system that uses feedback in a closed loop manner to self tune electrical properties of the output. The control unit is configured to instruct the sensor to (a) apply a sense pulse to the human tissues, (b) measure power dissipation of the sense pulse, (c) adjust a stimulation pulse based on the measured power dissipation, (d) apply the stimulation pulse to the human tissues based on the power dissipation and based on the program in order to maintain constant power output across each pulse, and (e) repeat steps (a)-(d).

Disclosed herein is a functional electrical stimulation (FES) device and system. In one embodiment, sequential bipolar pulse stimulation may be provided to an area of a living body via one or more electrode leads applied to the area via a FES device comprising a current pulse generating circuit comprising output nodes for operative coupling to the one or more electrode leads, and configured for operative coupling to a voltage supply. The current pulse generating circuit generally comprises positive and negative stimulation paths drawing from the voltage supply to respectively apply positive and negative currents through the area via the one or more electrode leads. In one example, the stimulation paths comprise respective capacitive elements, a capacitance ratio of which dictating, at least in part, an amplitude ratio of the positive and negative currents, wherein periodic alternative activation of the stimulation paths provides the sequential bipolar pulse stimulation. In another example, each path comprises a respective charging element and a respective activation switch, wherein each respective charging element is charged by the voltage supply and discharged upon activation of the respective activation switch to generate positive and negative current pulses respectively, such that a pulse rise time of the positive and negative current pulses is predominantly dictated by a switching speed of each respective switch. Systems and uses for these devices, and FES in general, are also described.
