Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

A fractional handpiece and systems thereof for skin treatment include a passively Q-switched laser assembly operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.

Disclosed herein is a medical RF apparatus using an RF pulse, comprising an RF generator, which generates a test pulse for detecting characteristics of tissue; a monitoring unit, which monitors the change in the information on the tissue state while the test pulse is transmitted to the tissue; and a measurement unit, which determines the tissue characteristics of a patient by comparing the values monitored in the monitoring unit with the reference data; and a method for controlling the same.

A treatment apparatus includes a motorized subsystem in a handpiece housing having a rotating output shaft, an axial cam driven in rotation by the output shaft, and a push rod linearly driven by the axial cam. A cartridge is removably attachable to the handpiece housing and includes a cartridge housing, a needle assembly, a piston in the housing engaging the needle assembly and linearly driven forward by the push rod, and a first biasing member urging the piston rearward.

An electrode arrangement is described that is configured to be coupled to a high voltage source for a dielectric barrier discharge plasma treatment of an irregularly three-dimensionally shaped surface of an electrically conducting body. The three-dimensionally shaped surface is used as a counter electrode. A first planar electrode is coupled to the high voltage source via a first lead, fitted to the object to be treated and brought in contact with a dielectric. A second electrode is contacted with the surface to be treated as reference electrode. The second electrode is provided in an edge portion that is circumferential to the first planar electrode and configured to be coupled to a reference voltage source via a second lead. An isolating cover layer covers the electrode and a third electrode covers the isolating cover layer as a ground electrode.

Embodiments described herein are directed to a system for providing alternating freeze and thaw cycles. The system includes a controller, a vessel for holding a working fluid, a pressure generator, a cooler, a cooler heat exchanger, a heater, a heater heat exchanger, a check valve, and a treatment instrument. In some embodiments, the treatment instrument includes a distal end, a proximal end, a connecting portion adjacent to the proximal end, a needle element adjacent the distal end, a handle portion disposed between the proximal and distal end, and a depth-limiting element to limit an injection depth of the needle element.

There is provided a phototherapy apparatus, in which the therapeutic light is delivered through one or more massage components. The massage component provides mechanical massage to the subject biological tissue and modifies the properties of the subject tissue in thickness, density, etc. to facilitate the absorption of the therapeutic light and enhance the effect of the phototherapy procedure. The light source of the phototherapy apparatus is actively cooled by a synthetic jet cooler.

Disclosed are a medicine injection tip that may smoothly insert and discharge a needle into and from skin, a hand piece, and a skin treatment device.

Cosmetic method and apparatus are provided that can provide cooling and/or freezing of skin tissue proximal to the skin surface to generate an appearance of lightening or reduced pigmentation in the skin. The skin can be cooled to a temperature of less than about −5 degrees Celsius for a duration of about one minute or less, using a cooled surface that is at least 3 cm in width. A cooling arrangement can be provided to provide controlled heat removal from the skin tissue being treated. A sensor can optionally be provided to detect freezing of tissue proximal to the cooled surface.

A medical RF apparatus using an RF pulse and a method of controlling the medical RF apparatus are provided. The medical RF apparatus includes an RF generator, which generates a test pulse for detecting characteristics of tissue, a monitoring unit, which monitors the change in the information on the tissue state while the test pulse is transmitted to the tissue, and a measurement unit, which determines the tissue characteristics of a patient by comparing the values monitored in the monitoring unit with the reference data.
