  • Publication number: 20190133673
    Abstract: Systems and methods utilizing RF energy to treat a patient's skin (e.g., dermis and hypodermis) or other target tissue including at a depth below a tissue surface (e.g., skin surface, mucosal surfaces of the vagina or esophagus) are provided herein. In various aspects, the methods and systems described herein can provide a RF-based treatment in which the deposition of RF energy can be selectively controlled to help ensure heating uniformity during one or more of body sculpting treatment (lipolysis), skin tightening treatment (laxity improvement), cellulite treatment, vaginal laxity or rejuvenation treatment, urinary incontinence treatment, fecal incontinence treatment, all by way of non-limiting examples. In various aspects, the systems can comprise one or more sources of RF energy (e.g., a RF generator), a treatment applicator comprising one or more electrode arrays configured to be disposed in contact with a tissue surface, and a return electrode (e.g., a neutral pad) to the tissue surface.

  • Publication number: 20190134421
    Abstract: In accordance with various aspects of the present teachings, systems and methods for applying treatment energy, e.g., electromagnetic radiation such as laser radiation in the visible and near infrared wavelengths, to body areas having bulges and fat deposits, loose skin, pain, acne and/or wounds. In some aspects, the systems and methods can enable relatively lengthy treatments to be performed by having the practitioner set-up and/or start the treatment, thereafter allowing the treatment to proceed safely and effectively without the continued presence of the practitioner.

  • Patent number: 9780518
    Abstract: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device positioned along the optical axis of the resonator.

  • Publication number: 20160256701
    Abstract: RF energy for skin conditioning with a non-ablative electrode is applied with a handpiece incorporating means to prevent electrical shock to the patient when the energized electrode surface makes or breaks contact with the skin In a preferred embodiment, switch means are incorporated in the handpiece and configured such that the active electrode surface is not energized until it is in actual contact with the patients skin, and remains energized only while the active electrode surface remains in contact with the patient's skin, so that no voltage is present on the electrode, when an air gap whose dielectric breakdown can cause an electrical shock to the patient arises, immediately before or immediately after skin contact during a skin conditioning procedure. In another preferred embodiment, the electrode to skin impedance change as the electrode touches the skin is used to activate a switch that transfers RF to the electrode.

  • Publication number: 20150005759
    Abstract: In part, the disclosure relates to an electromagnetic current displacement apparatus that includes one or more magnetic field sources and an alternating current source. The apparatus includes current delivery electrodes that may be part of a cuff, a hand held device, or individual electrode pads suitable for temporary fixation to skin. In one embodiment, an alternating current is transcutaneously delivered using skin contacting electrodes sized and arranged to avoid hotspots and provide a uniform delivery of the current. In turn, current attractors and repulsors can be arranged on the skin or in a suitable device to push or pull sections of the current that is disposed below such elements. Magnetic fields can be applied and focused to the regions through which the current passes, effectively pushing the current deeper into a target region below the surface of the skin.

  • Publication number: 20130178917
    Abstract: Disclosed herein are methods and systems for treatment, such as skin rejuvenation treatment, use non-uniform laser radiation. A high-intensity portion of the laser radiation causes collagen destruction and shrinkage within select portions of the treatment area, while a lower-intensity portion of the radiation causes fibroblast stimulation leading to collagen production across other portions of the treatment area. An output beam from a laser source, such as an Nd:NAG laser, is coupled into an optical system that modifies the beam to provide a large-diameter beam having a nonuniform energy profile, comprised of a plurality of high-intensity zones surrounded by lower-intensity zones within the treatment beam. The higher-intensity zones heat select portions of the tar et tissue to temperatures sufficient for a first treatment (e.g. collagen shrinkage), while the lower-intensity zones provide sufficient energy for a second treatment (e.g. stimulated collagen production).
