  • Publication number: 20240131365
    Abstract: Disclosed are devices suitable for treatment of subcutaneous tissue by transdermally-inducing ultrasonic vibrations in subcutaneous tissue and/or transdermally delivering energy with electromagnetic radiation such as light to subcutaneous tissue. In some embodiments, the treatment of subcutaneous tissue is effective in reducing the amount of subcutaneous fat therein. In some embodiments, transdermal radiation-delivery of energy and transdermal induction of ultrasonic vibrations in subcutaneous tissue can be performed simultaneously, alternatingly or in an unrelated fashion. In some embodiments, the device simultaneously transdermally-induces both ultrasonic transverse and ultrasonic longitudinal vibrations in subcutaneous tissue.

  • Patent number: 11045249
    Abstract: An electrode is disclosed for use in a system for heating biological tissue via RF energy. The electrode comprises a plurality of electrically conductive pins projecting from, and in electrical contact with, an electrically conductive common base. The base is connectible to a source of RF energy and the spaced ends of the pins remote from the base have contact regions for introducing RF energy from the source into the biological tissue. Each contact region is sufficiently small to achieve uniform dielectric heating in the biological tissue beneath the contact region at the frequency of the applied RF energy.

  • Publication number: 20180317998
    Abstract: Apparatuses and methods for thermally treating sweat glands in a volume of skin of a patient. A unipolar RF handpiece comprises a unipolar RF electrode and a bipolar RF handpiece comprises a supply electrode and a ground electrode, separated by an insulator. The unipolar RF handpiece applies RF waves into the volume of skin to dielectrically heat the sweat glands and the bipolar RF handpiece introduces RF current dielectrically heat the sweat glands. In some embodiments, the electrodes of the bipolar RF handpiece are arranged coaxially and are adjustable to allow for adjusting the depth of the RF current. In some embodiments the RF waves are applied first, heating the sweat glands and thus increasing their water content so the RF current can be applied to complete thermal disruption or destruction of the sweat glands without disrupting surrounding tissue.

  • Patent number: 9283029
    Abstract: A method for medical treatment includes bringing an applicator, having an array of protrusions disposed thereon, into proximity with a skin surface of a patient so as to maintain a space between a plurality of the protrusions and the skin surface. Radio-frequency (RF) electrical power is applied to the applicator so as to cause electrical discharges to be generated, in response to the RF electrical power, between the plurality of the protrusions and respective points on the skin surface via a fluid medium in the space.

  • Patent number: 9215788
    Abstract: Devices and methods for treating biological tissue using a plasma gas-discharge are disclosed herein. An electrode for igniting a gas flow to form a plasma gas-discharge, wherein the electrode is configured within the device such that upon encountering a surface of the biological tissue by the electrode, a path of current from the electrode to the surface of the biological tissue is formed, thereby igniting the gas flow and forming the plasma gas-discharge. In some embodiments, electromagnetic interactions between the treated biological tissue and the plasma gas discharge traversing the electromagnetic interaction gap shape the profile of the plasma gas discharge. According to some embodiments, the device includes an electrode for igniting gas of the gas flow, and electromagnetic interactions between the electrode and the skin determine, at least in part, the electromagnetic interactions that shape the profile of the plasma gas discharge.

  • Publication number: 20140142469
    Abstract: An apparatus and a method for treating adipose tissue located beneath a patient's skin is disclosed herein. In some embodiments, the apparatus includes a sonotrode 140 and an ultrasound transducer 130 operative to induce longitudinal and/or transversal ultrasound vibrations in a least a portion of the sonotrode 140. In some embodiments, the apparatus provides a “cold” or “transverse” mode where ultrasound energy delivered to the patient is primarily energy of transverse ultrasound waves, and a “hot” or “longitudinal” mode where ultrasound energy delivered to the patient is primarily energy of longitudinal ultrasound waves. The longitudinal waves may be useful for ‘pre-heating’ tissue of the patient before delivering the transverse waves.
