The automated scanning system includes a rotating multi-sector scanning element configured to repeatedly scan the input beam, each scan providing an array of output beams corresponding to the multiple sectors of the scanning element and forming a scanned row of treatment spots on the skin. The scanning element is configured such that each sector provides a constant-angular-direction output beam as that sector rotates through the input beam. The treatment spots of each scanned row are spaced apart from each other by areas of non-irradiated skin. The treatment spot control system provides a distance between adjacent rows of treatment spots in a direction of manual movement of the device.Type: ApplicationFiled: April 10, 2012Publication date: November 8, 2012Inventors: David Youngquist, Harvey I-Heng Liu, Jay M.

Publication number: 20120283711Abstract: A device for providing a dermatological treatment, the device includes a device body, a radiation delivery system for delivering radiation to the skin to provide a dermatological treatment, and a situation-specific control system. The control system includes a plurality of sensors and control electronics programmed to receive signals from the plurality of sensors; determine whether to initiate radiation delivery by the radiation delivery system based on a comparison of the signals received from the plurality of sensors to a first condition; and once radiation is initiated, determine whether to continue radiation delivery by the radiation delivery system based on a comparison of the signals received from the plurality of sensors to a second condition that is different than the first condition.Type: ApplicationFiled: April 10, 2012Publication date: November 8, 2012Inventors: Harvey I-Heng Liu, David Youngquist, Tobin Island

Publication number: 20120283709Abstract: A self-contained, hand-held device for providing a dermatological treatment includes a radiation source configured to generate one or more radiation beams, and an optical system configured to deliver the one or more radiation beams to the skin to provide a dermatological treatment. Each radiation beam includes a first axis beam profile and an orthogonal second axis beam profile. The optical system includes a first axis optic configured to influence the first axis beam profile of each radiation beam by a greater extent than the second axis beam profile of each radiation beam, and a second axis optic configured to influence the second axis beam profile of each radiation beam by a greater extent than the first axis beam profile of each radiation beam.Type: ApplicationFiled: April 10, 2012Publication date: November 8, 2012Inventors: Patrick Reichert, David Youngquist, Mark V.

Publication number: 20120271289Abstract: We describe devices, methods, and systems used for hair removal. In particular, we describe hair removal devices, particularly epilation devices, methods of using those devices, and systems including those hair removal devices. Our hair removal devices include, in combination, a.) at least one primary energy source that applies that energy, e.g., radio-frequency (RF), high intensity focused ultrasonic (HIFU) energy, or high intensity light, e.g., intense-pulsed light (IPL) or light from flash lamps or lasers, to the skin or to hair in a continuous, semi-continuous, or pulsed mode and b.) a hair removal component or components, such as rotary mechanical hair removal structures or epilators, that perform a mechanical hair removal step. Auxiliary treatment or control components such as comparatively lower power heaters, ultrasound devices, coolers, impedance measurement devices, etc. may also be included in the combination or used in conjunction with our combination device.Type: ApplicationFiled: January 22, 2008Publication date: October 25, 2012Applicant: Syneron Medical Ltd.Inventors: Shimon Eckhouse, Tuvia-Dror Kutscher, Amit Meridor, Danny Ayre

Patent number: 8291913Abstract: Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.Type: GrantFiled: August 18, 2008Date of Patent: October 23, 2012Assignee: Reliant Technologies, Inc.Inventors: David Eimerl, Leonard C.

Patent number: 8286640Abstract: A fractional treatment system can be configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue increases as the tissue is heated by the laser (e.g., 1390-1425 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 8 cm?1 to about 30 cm?1. An adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. The system may be designed to be switchable between a treatment mode that is semi-ablative and a treatment mode that is not semi-ablative. Adjustment of these parameters can improve the efficiency and efficacy of treatment.Type: GrantFiled: November 29, 2010Date of Patent: October 16, 2012Assignee: Reliant Technologies, Inc.Inventors: Kin F.

Patent number: RE43881Abstract: A laser treatment device and process with controlled cooling. The device contains a cooling element with high heat conduction properties, which is transparent to the laser beam. A surface of the cooling element is held in contact with the tissue being treated while at least one other surface of the cooling element is cooled by the evaporation of a cryogenic fluid. The cooling is coordinated with the application of the laser beam so as to control the temperatures of all affected layers of tissues. In a preferred embodiment useful for removal of wrinkles and spider veins, the cooling element is a sapphire plate. A cryogenic spray cools the top surface of the plate and the bottom surface of the plate is in contact with the skin. In preferred embodiments the wavelength of the laser beam is chosen so that absorption in targeted tissue is low enough so that substantial absorption occurs throughout the targeted tissue. In a preferred embodiment for treating large spider veins with diameters in the range of 1.Type: GrantFiled: June 21, 2011Date of Patent: December 25, 2012Assignee: Reliant Technologies, Inc.Inventors: Eugene Baranov, Nikolai I.
