  • Publication number: 20210244470
    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 (e.g., a Pockels cell) positioned along the optical axis of the resonator.

  • 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: 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.
