摘要:
The invention describes a treatment for skin containing selected targets that provides feedback in response to a measurement enabled by the ablation of holes. The inventive apparatus includes an electromagnetic source configured to emit ablative electromagnetic energy, a delivery system, a sensing element, and a controller. The delivery system can be configured to receive ablative energy from the electromagnetic source and deliver it to multiple discrete locations at the selected region to form a pattern of discrete holes in epidermal and dermal tissue of the skin. The lipid content a portion of the tissue can be evaluated using a sensing element. At least one pulse of electromagnetic energy is delivered to the skin under control of a controller in response to the result of a measurement by the sensing element. The apparatus may include a positional sensor to provide additional dosage control, particularly when the inventive method is used with a continuously movable handpiece.

A mechanical element allows the tip of the handpiece of a dermato logical treatment system to rotate to adjust for deviations in handpiece angle with respect to the surface of the treatment area. The tip may glide over the surface of the skin, the tip may include wheels or rotating cylinders on which the tip rolls across the skin, or the tip may be removed from the skin and placed in a new location in a stamping motion. The tip of the handpiece rotates around a single axis, or around two perpendicular axes, so that pressure on the tip moves the flat surface of the tip into proper orientation for planar contact with the skin. An element can be included in the handpiece to apply a restoring force on the tip so that the tip rests in its optimal position in the absence of external forces.

摘要:
A handpiece for treatment of the surface of a target tissue with at least one light beam is provided, the handpiece including a housing, at least one light source for generating at least one light beam, an opening for allowing the emission of the at least one light beam out of the housing and towards the target surface, a mechanism for controlled displacement of the at least one light source to move the at least one light beam across the target surface; and a controller for controlling the mechanism. A method is provided for treating a tissue surface with a light beam that includes directing a light beam towards the tissue surface, focusing the light beam at the tissue surface so that the focal point is positioned proximate the surface of the tissue so that the diameter of the light beam is smaller at the surface of the tissue than below the surface. The light beam is moved to create a pattern on the tissue, and it is moved in response to manual movement of the handpiece to overcome unwanted movements and provide a desired spot pattern on the tissue surface.

A compact and portable optical shaving device cuts hair shafts using electromagnetic radiation. In various embodiments, the optical shaving device includes a power source that connects to one or more optical components (e.g., arranged in an array). An optic, such as a blade, can connect to and aligns with the array of optical components. The optical component(s) can provide light to the optic based on electrical energy from the power source. The optical component(s) or the optic can manipulate and direct the electromagnetic radiation to cut the hair shafts.

The present invention is directed to techniques in the field of surgical systems, devices, and methods of use for skin reduction, tightening, or excision, and more particularly, to methods, systems, and devices for removing skin in tissue reduction laser surgery for the removal of skin wrinkles, laxities, or the like with minimal scarring after healing. The systems, devices, and methods of the present invention are adapted to control laser light energy to irradiate tissue such that the laser reduces, such as through vaporization, tissue in laser surgery. The present systems are adapted to use at least one laser device in conjunction with conventional and novel excision array shaping means, fiber optic light guides, distribution cylinders, stepping motors, computer programs, surgical techniques or the like therefor.

Methods and apparatuses for contouring, shaping and/or directionally shrinking tissue by selective application of energy are disclosed herein. One embodiment of a method of contouring tissue includes determining a contraction direction along which the tissue is to be preferentially contracted and applying energy to a plurality of discrete elongated exposed regions of tissue spaced apart from each other among non-exposed regions of tissue. At least one of the exposed regions can be oriented such that a longitudinal dimension of the exposed regions is generally transverse to the contraction direction.
摘要:
A device comprises an energy source capable of generating short bursts of energy at a variable pulse repetition rates. The repetition rates range from a single shot to several hundreds Mega-Hertz so that selective, three dimensional interactions with a volumetric zone of skin or issue can be created substantially without damage or substantial changes to overlying or underlying or surrounding tissue or skin.

An energy treatment system to treat a patient includes an energy delivery device having a plurality of energy emitters used in combination with an energy activatable drug. A mask can be used to define a treatment area. Energy from the energy emitters passes through an optical window of the mask to activate a cosmetically and/or therapeutically effective amount of the activatable drug at the target site to bring about a desired change of tissue, for example, to reduce visibility of one or more blood vessels, while energy from the energy emitters directed outside of the target site is blocked by the mask.
