Patent number: 11045249Abstract: 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.Type: GrantFiled: July 30, 2014Date of Patent: June 29, 2021Inventors: Alexander Britva, Alexander Dverin, Ziv Karni

Publication number: 20180317998Abstract: 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.Type: ApplicationFiled: July 19, 2018Publication date: November 8, 2018Inventors: Alexander Britva, Ziv Karni, Joseph Lepselter
