Abstract: Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.

Abstract: Dermatological systems and methods for providing a therapeutic laser treatment of tissue having poor chromophore selectivity using a laser source having a grating element to provide laser light having reduced linewidth. In some embodiments, the linewidth is reduced by at least half compared to the linewidth that would be provided in a system without the grating filter element. The linewidth may be reduced in some cases to 500 GHz or less, 300 GHz or less, or 200 Hz or less.

Abstract: Systems and methods for applying energy to treat body areas having fat deposits are disclosed in which treatment energy is applied to a patient with a plurality of energy applicators each in contact with a target body subarea of the patient's skin, thereby heating the skin and underlying tissue, including fat. The temperature of fat tissue of each target body subarea may be sensed, and the application of energy to the corresponding energy applicator may be terminated if the temperature exceeds a maximum temperature for the subarea, which may be individually defined by a system user.

Abstract: Systems and methods for applying energy to treat body areas having fat deposits, cellulite, or loose skin are disclosed. The treatment energy is applied to a patient with multiple applicators in contact with the patient's skin, which heats the skin and underlying tissue, such as fat. As the temperature of the fat is raised and maintained for a period of time, the heat damages the fat cells. When multiple applicators apply energy to multiple treatment subareas within a general area of a patient's body at interleaving intervals, treatment efficiency is improved. In particular, compared to applying energy continuously to treat each subarea one at a time, applying energy in interleaving intervals sequentially to the various subareas reduces the total treatment time by having multiple subareas treated simultaneously while maintaining the temperature of the target tissue (e.g. fat) within the therapeutic temperature range.

Abstract: Disclosed herein are systems and methods for preferentially heating subcutaneous tissue. Systems for heating subcutaneous tissue may comprise one or more radio-frequency (RF) electrodes having contoured tissue contacting surfaces, such as electrodes with concave or convex surface contours. Methods may comprise applying RF voltage or current from one or both of the handpieces to attain a target tissue and/or electrode temperature and to maintain the tissue and/or electrode at that temperature.
