Abstract: Treatment systems, methods, and apparatuses for improving the appearance of skin and other treatments are described. Aspects of the technology are directed to improving the appearance of skin by reducing a vascular structure. A non-invasive cooling device can cover and cool the vascular structure to affect the blood vessels of the vascular structure.

Abstract: Treatment systems, methods, and apparatuses for improving the appearance of skin and other treatments are described. Aspects of the technology are directed to improving the appearance of skin by transcutaneously cooling and affecting nerve tissue so as to inhibit facial muscular contractions and thereby reduce dynamic wrinkling. A non-invasive nerve cooling device can be applied to the subject's head to attenuate nervous system signals to facial muscles.

Abstract: Treatment systems, methods, and apparatuses for treating acne, hyperhidrosis, and other skin conditions are described. Aspects of the technology can include cooling a surface of a patient's skin and detecting changes in the tissue. The tissue can be cooled a sufficient length of time and to a temperature low enough to affect glands or other targeted structures in the skin.

Abstract: Systems and methods that enable tissue cooling and delivery of energy for altering tissue are described herein. Aspects of the disclosure are directed to, for example, heating tissue at treatment zones to ablate, denature, reorganize, coagulate, or otherwise alter the tissue to affect the cosmetic appearance of the patient. The method can include, for example, removing heat from the target region of the human subject before, during, and/or after energy delivery to cool tissue to a temperature below normal body temperature to inhibit pain.

Abstract: Systems for treating a subject's tissue can include a thermally conductive cup, a tissue-receiving cavity, and a vacuum port. The vacuum port is in fluid communication with the tissue-receiving cavity to provide a vacuum for drawing the submental tissue, or other targeted tissue, into the tissue-receiving cavity. A thermal device can cool and/or heat the conductive cup such that the conductive cup non-invasively controls the temperature of subcutaneous lipid-rich cells in the tissue. A restraint apparatus can hold a the conductive cup in thermal contact with the target region.

Abstract: Treatment systems, methods, and apparatuses for improving the appearance of skin or other target regions are described as well as for providing for other treatments. Aspects of the technology are directed to improving the appearance of skin by tightening the skin, improving skin tone or texture, eliminating or reducing wrinkles, increasing skin smoothness, or improving the appearance of cellulite. Treatments can include cooling a surface of a patient's skin and detecting at least one freeze event in the cooled skin. The treatment system can continue cooling the patient's skin after the freeze event(s) are detected so to maintain at least a partially frozen state of the tissue for a period of time.

Abstract: Treatment systems, methods, and apparatuses for improving the appearance of skin or other target regions are described. Aspects of the technology are directed to improving the appearance of skin by tightening the skin, improving skin tone or texture, eliminating or reducing wrinkles, increasing skin smoothness, or improving the appearance sites with cellulite. Treatments can include cooling a surface of a patient's skin and detecting freezing in the cooled skin. The tissue can be cooled after the freeze event is detected so to maintain the frozen state of the tissue to improve the appearance of the treatment site.

Abstract: Compositions and formulations for use with devices and systems that enable tissue cooling, such as cryotherapy applications, for alteration and reduction of adipose tissue are described. Aspects of the technology are further directed to methods, compositions and devices that provide protection of non-targeted cells (e.g., non-lipid-rich cells) from freeze damage during dermatological and related aesthetic procedures that require sustained exposure to cold temperatures. Further aspects of the technology include systems for enhancing sustained and/or replenishing release of cryoprotectant to a treatment site prior to and during cooling applications.

Abstract: The present invention provides methods and apparatus for controlling light-induced tissue treatment. In accordance with various aspects of the present invention, the invention provides for improved, real-time control of the light beam operational parameters which enables greater safety, efficiency, uniformity and continuity of the treatment process.

Abstract: A counter-rotating disk scanner together with another scan mechanism provides two-dimensional optical scanning. The counter-rotating disk scanner includes counter-rotating scan disks that implement the scanning action as they rotate through an optical axis of the system.

Abstract: An apparatus (12) generates information about the width of pulses in an optical train using an autocorrelation technique. In the apparatus, the incoming beam (10) is split into two paths (10a, 10b). The path length of one of the beams (10b) is varied using a reciprocating stage (40) having a reflector (50) mounted thereon. The stage is driven by a cam (42) rotating at a constant speed. A portion (42b) of the curvature of the cam is arranged such that the distance between the rotational axis (44) of the cam and the stage varies proportionally with the rotational angle of the cam such that the path length of the beam will change at a constant rate. The two beams are then recombined in a second harmonic generation crystal (28) which generates an output signal. The output signal is monitored by a photodetector (30) and may be displayed on an oscilloscope to provide a measurement of the pulse width of the input pulses.
