Methods and apparatuses for treating a tissue with an electric treatment by rotating a pattern of electrodes partway through a treatment is disclosed. Also described herein are methods and apparatuses to treat tissue, including treating skin disorders, by selectively de-nucleating epidermal cells without provoking a significant inflammatory response, e.g., without increasing the density of leukocytes in the treated skin, and without affecting the non-cellular components of the dermis.

This application discloses configurations for arranging transducer arrays on a person's head to impose tumor treating fields (TTFields) in the brain at field strengths that are as uniform as possible throughout the entire brain. In some embodiments, L-shaped sets of electrodes are positioned near the right and left ears, each with a horizontal arm above the ear and a vertical arm behind the ear. Optionally, these embodiments may be combined with a second pair of electrodes positioned on top of the head and behind the neck. In other embodiments, one pair of electrodes is positioned above the right ear and on the left/rear portion of the neck; and a second pair of electrodes is positioned above the left ear and on the right/rear portion of the neck. These configurations improve the uniformity of the electric fields imposed throughout the brain, and are particularly useful for preventing and/or treating metastases.

A tumor treating system for the delivery of tumor treating electric fields to a patient including a control device, a field generator, and electrodes. The control device has a frequency range, a firing configuration and a firing sequence. The field generator generates electrical signals within the frequency range. The electrodes are placed in optimized locations on the patient. Each electrode includes a ceramic layer, a metalized layer and a circuit element. The metalized layer is coupled to the ceramic layer on one side of the ceramic layer. The metalized layer has an outer surface facing away from the ceramic layer. The circuit element is coupled to the metalized layer. The coupling of the circuit element to the metalized layer is across substantially all of the outer surface of the metalized layer. The circuit element conducts the electrical signals to the metalized layer as directed by the control device.

Devices, systems and methods are disclosed for electrical stimulation of the vagus nerve to treat or prevent symptoms of headache in a patient. The headache may include primary headache, such as migraine and cluster headache, or secondary headache resulting from an underlying medical condition, such as post-concussion headache. The methods comprise transmitting impulses of energy to the vagus nerve according to a treatment paradigm that includes single doses of between about 30 seconds to about 5 minutes. The electrical impulses may have a frequency of about 1 kHz to about 20 kHz.

The flexible mask includes a first flexible layer, a second flexible layer, a plurality of functional layers located between the first flexible layer and the second flexible layer, and a plurality of electrodes electrically connected with the plurality of functional layers. The functional layer includes a carbon nanotube layer including a plurality of carbon nanotubes uniformly distributed. The flexible mask is electrically coupled with the controller via the plurality of electrodes.

The present invention relates to an apparatus for fractional treatment of skin tissue of a patient comprising a handpiece, at least one first electrode and at least one second electrode, arranged on a base plate for applying radio frequency energy, to at least one layer of the skin, wherein the apparatus is adapted to apply electrical energy to the skin tissue with a first pulse and a second pulse following the first pulse, with the first pulse being a low energy level pulse and the second pulse being a high energy level pulse having a higher energy level than the low energy level pulse.

A garment structure having an adjustment mechanism for abutting at least one pad unit against a human body includes a garment body, at least one adjustment belt, and at least one pad unit being an electrode pad unit, a heating pad unit, or an electrode pad unit with a heating unit. The adjustment belt has one end connected to the garment body, and another end fixed to an outer surface of the garment body. When the adjustment belt is pulled tight, the garment body is dragged to move toward the skin. The pad unit is disposed on the garment body, and moves, along with a portion of the garment body being dragged, to abut against the skin. A user wearing the garment structure can pull and secure the adjustment belt to enable the pad unit to easily and quickly abut against the skin to proceed with electrotherapy and/or heat therapy.

TTFields therapy is a proven approach for treating tumors using electric fields. This application describes systems and methods for measuring the temperature at the electrode elements of the transducer arrays that are used to apply the TTFields to a subject. A distal circuit is positioned adjacent to each transducer array, and the distal circuit interfaces with temperature sensors in the transducer array to obtain temperature readings. Those temperature readings are transmitted to a central hub. In some embodiments, temperature measurements from all of the distal circuits occur simultaneously.

A device for electrical stimulation of one or more components of the periodontal complex and surrounding tissue of a tooth, for uses such as reducing orthodontic pain and encouraging tooth movement, has electrodes of a rigid, electrically conductive material in a fixed spatial relationship configured for application to oral mucosa and attached gingiva adjacent to, and along a periodontal ligament of, a root structure of a single tooth. An electrical circuit is configured for electrical connection to the at least two electrodes. The electrical circuit has an output providing a subsensory electrical stimulus comprising a waveform in accordance with predetermined stimulation parameters. After the electrodes are applied to the oral mucosa and attached gingiva adjacent to, and along the periodontal ligament of, a root structure of the tooth, a switch, when activated, activates the electrical circuit to output the electrical stimulus through the at least two electrodes.

Devices, systems and methods are disclosed for electrical stimulation of the vagus nerve to treat or prevent disorders in a patient. The methods comprise transmitting impulses of energy to the vagus nerve according to a treatment paradigm. The treatment paradigm may include generating and transmitting the electrical impulse as a single dose from about 30 seconds to about 5 minutes. The treatment paradigm may comprise a treatment session of 2 to 4 times within an hour time period and/or as a single dose from 2 to 5 times during a day.
