Abstract: A skin or body treatment device includes one or more removable and replaceable modules. Each module is configured to provide a skin or body treatment, underlying tissue treatment, or both. One or more applicators are coupled with the skin or body treatment device. Each applicator enables the use of the one or more removable modules to effect the skin or body or underlying tissue treatment. A selected skin or body treatment, underlying tissue treatment, or both can be implemented and performed upon selection and configuration of the one or more removable and replaceable modules and the one or more applicators required for the selected treatment.

Abstract: The invention relates to the use of low intensity light therapy for the treatment of various medical conditions, either alone, or in combination with a second procedure.

Abstract: Devices and methods for utilizing electromagnetic radiation and other forms of energy to treat a volume of tissue at depth are described. In one aspect, a device modulates the flux incident on surface tissue to control and vary the depth in the tissue at which an effective dose of radiant energy is delivered and, thereby, treat a specific volume of tissue. The methods and devices disclosed are used to perform various treatments, including treatments to relieve pain and promote healing of tissue.

Abstract: A method is provided for facilitating the atrophying of a tonsil or adenoid ("organ") to cause the gradual removal thereof from the patient. A laser is positioned adjacent the organ, the wavelength for the laser being in the 700 nm to 1100 nm range and having energy sufficient to cause coagulation of blood in at least a significant number of the organ vessels over a period of several minutes, but not so much energy as to kill significant tissue of the organ or to cause significant damage to tissue adjacent to the organ. The laser is then turned on to irradiate the organ with laser energy and the entire exposed area of the organ is painted or otherwise irradiated. Irradiation continues until a selected condition of the organ, tissue adjacent the organ and/or laser source occurs.

Abstract: An endophotocoagulation probe has a probe tip adapted for insertion into the eye of a subject, and includes an optical fiber for carrying light, and a lens for focusing the light from the end of the fiber onto target tissue at a desired working distance. The lens forms a convergent beam with the waist of the beam providing a spot of maximum power density whose size is independent of the ocular medium. In a preferred embodiment a positioner provides selective variation of the spacing between the lens and the fiber to select a desired spot size. Preferably the lens is a selfocal or rod lens. A step-positioning handle selects one of a plurality of determined spacings, so as to achieve plural different spot sizes, each having a predetermined power density. Examples of probes having variable spot sizes in ranges from 50 to 500 microns are described with particular fibers and selfocal lens elements. A microprocessor may control lens position and light input power in accordance with the selected spot size.
