Abstract
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.
Claims23
A device for treating a region of intact living skin having a surface and an epidermal/dermal junction, comprising:
- an energy source coupled with at least one diffractive optic;
- and
- a controller that operates the energy source to target a plurality of beams below the surface of the skin and create a plurality of cavities below the surface of the skin in a 3-dimensional pattern within the thickness of the skin without any thermal damage deeper than 5 μm below the plurality of cavities.
A device for treating a region of a target having a surface comprising:
- an energy source coupled with at least one multiple beam generating optic;
- and
- a controller that operates the energy source to direct said plurality of beams below the surface of the target and create a plurality of disruptions below the surface in a 3-dimensional pattern within the thickness of the target without any thermal damage further than 5 μm below the plurality of disruptions.
A method of modifying a region of skin, comprising:
- providing a beam generator to produce a plurality of beams with at least one diffractive optic;
- targeting the plurality of beams below the surface of the t with a controller;
- and
- creating a plurality of cavities below the surface of the skin in a plurality of layers within the thickness of the skin in a 3-dimensional pattern within the thickness of the skin without any thermal damage deeper than 5 μm below the plurality of cavities, whereby the plurality of cavities create scattering centers to decrease the amount of light penetrating the skin.
A method of modifying a region of a target, comprising:
- providing an energy source to produce a plurality of beams with at least one multiple beam generating optic;
- directing the plurality of beams below the surface of the target with a controller that operates the beam generator;
- and
- creating a plurality of disruptions below the surface of the target in a 3 dimensional pattern within the thickness of the target without any thermal damage further than 5 μm below the plurality of disruptions, whereby the plurality of disruptions create scattering centers to decrease the amount of light penetrating deeper into the target.
