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.

A power supply for driving the gas discharge lamp is selectively controlled to drive the gas discharge lamp to output a first electromagnetic treatment when an area of skin being treated has a pigmented lesion, and to drive the gas discharge lamp to output a second electromagnetic treatment when the area of skin being treated has a vascular lesion, where the second electromagnetic treatment has a spectral distribution that is blue-shifted relative to the spectral distribution of the first electromagnetic treatment.

Abstract: A system and method for providing treatments of electromagnetic radiation to areas of post-partum abdominal skin. The treatments provide for raising the temperature in a portion of post-partum abdominal skin to a treatment temperature, which is sufficient to reduce the laxity or redundancy of the post-partum skin. In one embodiment the treatment can provide treatment exposures to sub-areas, of an area of post-partum abdominal skin which has been identified for treatment, and bring a temperature of the tissue being treated to at 50° C.

Abstract: A system and method for using a light source to treat tissue with NIR light. The operation provides for generating higher temperatures in deeper layers of tissue relative to higher layers of tissue. The increased temperature in dermal layers can operate to induce collagen shrinkage, or remodeling. One of the light sources for providing a broad spectrum of NIR light is a filament light. The light from the filament lamp can be selectively filtered, and after filtering this light is applied to the skin, where the selective filtering can enhance the ability to elevate the temperature of deeper layers of tissue, relative to layers of tissue which are closer to the surface of the skin.

Abstract: A dermatological treatment method includes directing laser energy having a wavelength of 2.79 ?m onto skin.

Abstract: An electro-surgical system actively maintains an optimal heating profile at the electrode-patient contact surface under varying load resistivity, thereby reducing the risk of burns and maximizing patient comfort. A set of temperature sensors is integrated within the electrode assembly of the electrosurgical system. The sensors are located both at the center and the edges of the electrode. The sensors are thermally coupled to the electrode-patient contact surface. As RF power is applied, a control loop monitors the temperature at the center and edges of the electrode. If the edge temperature of the electrode is high compared to its center temperature, then the control loop increases the operating frequency, effectively driving heat towards the center of the electrode. Conversely, if the edge temperature of the electrode is low compared to its center temperature, then the control loop decreases the operating frequency, effectively driving heat towards the edges of the electrode.
