摘要:
The application discloses a number of apparatuses suitable for selective skin treatment. In one example, a pair of RF electrodes is applied to skin. The RF electrodes receive RF energy from an RF energy generator. The RF electrodes are also configured to apply positive pressure to a segment of skin located between the pair of RF electrodes to partially or completely occlude the blood flow in one or more vessels in the segment of skin located between the pair of RF electrodes. Occlusion of the blood flow reduces heat dissipation by the skin segment located between the pair of RF electrodes and supports further increase of temperature of both the skin segment and vessels located between the pair of electrodes.
摘要:
Treating biological tissue can include selecting a parameter for electromagnetic radiation based on at least one parameter of a target region within the biological tissue. Treating biological tissue also includes methods, systems, and kits for delivering the electromagnetic radiation through a surface of the biological tissue to the target region to induce within the target region a sub-surface thermal injury characterized, for example, by a desired degree and a desired depth and confining the sub-surface thermal injury to substantially within the target region.

摘要:
A method for generating a long effective pulse duration output beam of laser radiation using a flashlamp-excited dye laser is described. A spaced series of excitation pulses is electronically generated using a pulse forming module. The series of excitation pulses are provided to a flashlamp-excited dye laser, which generates an output beam of laser radiation. The output beam is comprised of a series of spaced micropulses of laser radiation which, in combination, provide a long effective pulse duration.
摘要:
A method for treating wrinkles in skin involves the use of a beam of pulsed, scanned or gated continuous wave laser or incoherent radiation. The method comprises generating a beam of radiation, directing the beam of radiation to a targeted dermal region between 100 microns and 1.2 millimeters below a wrinkle in the skin, and thermally injuring collagen in the targeted dermal region. The beam of radiation has a wavelength of between 1.3 and 1.8 microns. The method may include cooling an area of the skin above the targeted dermal region while partially denaturing the collagen in the targeted dermal region. The method may also include cooling an area of the skin above the targeted dermal region prior to thermally injuring collagen in the targeted dermal region.
