A trial stimulation system includes a trial electrical stimulator. Additionally, systems for securing a disposable trial stimulator to the body of a patient are described, which may function to improve the durability of the system during the trial period and reduce the risk of damage or malfunction to the system due to lead/electrode dislocation and/or off-label uses like showering or bathing with the trial stimulator still secured to the body.

The disclosed systems and methods include a neuromodulation system including at least one neuromodulation device, at least one neuromodulation pattern storage means, and at least one neuromodulation controller. The neuromodulation pattern storage means can store neuromodulation data. The neuromodulation data can specify neurostimulation with at least one of a carrying frequency of at least 1 kHz or multipolar stimulation. The neuromodulation device can provide neuromodulation according to the neuromodulation data.

Disclosed herein are systems and methods for electrically modulating tissue. Systems can include a current generator; at least one implantable working electrode, the at least one implantable working electrode configured to be in electrical communication with the current generator; at least one indifferent electrode; and a controller configured to signal the current generator to: generate a set of currents with a set of initial polarities to be delivered to the working electrodes; and wherein the at least one indifferent electrode absorbs a bias current which is equal in magnitude and opposite in polarity to a summation of the set of currents.

Devices, systems and methods are provided for treating post-operative symptoms following major surgery and/or for treating patients in critical or intensive care. A method includes positioning a contact surface of a device in contact with an outer skin surface of patient and applying an electrical impulse transcutaneously from the device through the outer skin surface of the patient to a vagus nerve in the patient for about 60 seconds to about 5 minutes. The electrical impulse is sufficient to modify the vagus nerve such that the symptoms are reduced. A stimulation protocol is provided that includes two or more doses administered per day for a period of time sufficient to relieve the symptoms. The doses may be administered before and after the patient's surgery, or while the patient is being treating in intensive care.

Methods and apparatus for the treatment of the eye to reduce pain can treat at least an outer region of the tissue so as to denervate nerves extending into the inner region and reduce the pain. For example, the cornea of the eye may comprise an inner region having an epithelial defect, and an outer portion of the cornea can be treated to reduce pain of the epithelial defect. The outer portion of the cornea can be treated to denervate nerves extending from the outer portion to the inner portion. The outer portion can be treated in many ways to denervate the nerve, for example with one or more of heat, cold or a denervating noxious substance such as capsaicin. The denervation of the nerve can be reversible, such that corneal innervation can return following treatment.

A method for treating conditions associated with thalamocortical dysrhythmia. The method includes applying transcranial low voltage electrical stimulation (TLVES) therapy or transcranial magnetic stimulation (TMS) therapy to a patient in need thereof, and administering to the patient a dissociative anesthetic during the TLVES therapy or the TMS therapy. A number of conditions including tinnitus, depression and pain can be treated with TLVES or TMS in combination with the dissociative anesthetic, such as an NMADR inhibitor, including ketamine.

Methods, systems and devices for treating chronic pain by inducing stimulation to a predetermined region of the brain and measuring neural activity response to the stimulation and evaluating a neuroplasticity and/or excitability of neural-structures in a predetermined brain region, then stimulating the predetermined brain region to treat the chronic pain.

A system for percutaneously applying electrical stimulation to target nerve tissue to treat a patient having peripheral neuropathy includes a percutaneous electrode assembly, a power supply, and a pulse generator electrically coupled to the percutaneous electrode assembly and the power supply, the pulse generator configured to deliver electrical stimulation to the target nerve tissue via the percutaneous electrode assembly at a level that initiates vasodilation of vasculature within or adjacent the target nerve tissue, where the vasculature is responsible for perfusing the target nerve tissue and the electrical stimulation is delivered with a carrier frequency in the range of 25 kHz to 500 kHz.

A system, device, and method for transcutaneous nerve stimulation such as facial nerve stimulation, and in particular, to using transcutaneous nerve stimulation for artificially eliciting eye blink, such as with humans with acute facial paralysis (Bell's palsy or Dry Eye syndrome), is disclosed. A battery-operated wearable device may employ a pulse generator for periodically and automatically generating bursts train of asymmetrical Bi-Phasic square pulses. The output pulses are fed to two electrodes that are attached to the skin of the treated person to stimulate the facial nerve for eliciting blinking at a rate that mimics normal blinking operation. The device may include a sensor and a wireless connection, and the parameters of, or the activation of, the generated bursts may be controlled by the sensor output, by human user control, or by data received from the wireless network. Further, the device may transmit status to the wireless network.

A trial stimulation system includes a trial electrical stimulator. Additionally, systems for securing a disposable trial stimulator to the body of a patient are described, which may function to improve the durability of the system during the trial period and reduce the risk of damage or malfunction to the system due to lead/electrode dislocation and/or off-label uses like showering or bathing with the trial stimulator still secured to the body.
