The systems can provide hands-free delivery of electrical stimulation therapy over a predetermined set of time. | 2022-07-28 |
20220233850 | METHOD AND SYSTEM WITH CURRENT REGULATOR BIASED BY FLOATING POWER SUPPLY - A system and method are provided that include a power supply having positive and negative terminals. The negative terminal defines a reference ground. First and second electrodes are positioned within a patient and configured to be located proximate to tissue of interest that is associated with a target region. A control circuit is configured to control delivery of current for a therapy between the first and second electrodes. A current regulator (CR) circuit is connected to, and configured to control current flow through, at least the first electrode during delivery of the therapy under direction of the control circuit. A floating power supply is connected across power supply terminals of the CR circuit. The CR circuit and floating power supply are coupled to a floating ground node that is electrically separate from the reference ground. | 2022-07-28 |
20220233851 | METHOD AND DEVICE FOR SKIN TREATMENT BY MUSCLE STIMULATION AND PRESSURE - A method and a system for skin treatment are presented. A muscle stimulating element is configured to provide muscle stimulation to a muscle layer located below the skin tissue, at least one pressure application element is configured to apply pressure on the skin tissue, a handheld applicator is configured to be placed in vicinity of the skin tissue to deliver said muscle stimulation from said muscle stimulating element and said pressure from said at least one pressure application element to one or more muscles in the muscle layer located below the skin tissue; and a control board is configured and operable to activate the muscle stimulating element and the at least one pressure application element according to one or more activation patterns adapted to provide one or more treatments to the skin tissue. | 2022-07-28 |
20220233852 | DEVICE FOR RADIO-FREQUENCY SKIN TREATMENT - A coupling arrangement including a coupling member arranged on a skin contact surface of an electrode of a radio-frequency (RF) skin treatment device for electrically coupling the electrode to a user's skin. The coupling member includes a first layer and a second layer. The first layer has a first electrically conductive material configured to be arranged on the skin contact surface via one side of the first layer. The second layer has a second (different) electrically conductive material arranged on the first layer, on an opposite side of the first layer. The first layer has a thickness in a range from 10 μm to 100 μm, and the first electrically conductive material has a modulus of elasticity of at least 100 kPa. The second layer has a thickness of 10 μm or less, and the second electrically conductive material has a viscosity of 1,000 CPS or less. | 2022-07-28 |
20220233853 | SYSTEMS AND METHODS FOR TREATING TUMORS USING TARGETED NEUROSTIMULATION - A method for treating diagnosed or suspected tumors of a subject, comprising obtaining a target map that identifies an actual or likely location of the tumor in the subject, and providing multifocal non-invasive electrical stimulation with a duration, spatiotemporal pattern, current intensity, electrode montage, and/or regimen sufficient to do one or more of the following: (1) reduce the size of one or more tumor(s), (2) alter its/their perfusion, (3) change its/their metabolic or electrical activity, (4) change its/their functional connectivity profile, (5) slow down or stop its/their progression/spread and related symptomatology, (6) characterize one or more tumor(s) based on its/their response to noninvasive brain stimulation; possibly in conjunction with optimized anatomical changes applied to the skin or skull to better steer currents and fields into the tumor. | 2022-07-28 |
