Abstract: A method and apparatus are disclosed for improving bodily safety during exposure to an intense pulsed light source by diverging the light, such as with a diffuser. At a first position of the distal end of the light source the energy density of exit light from the distal end is substantially equal to the energy density of the light required for desired applications, such as effecting an aesthetic improvement without appearance of purpura or scarring, and at a second position of the distal end the radiance of the light emitted therefrom is significantly less than the radiance of the intense pulsed light. Eye safety is further enhanced by attaching at least one element of adjustable opacity to the handpiece of the light source, so that subcutaneously backscattered light may be absorbed by the at least one element.

Abstract: An apparatus adapted to inhibit pain signals generated by pain receptors in the skin during a skin related medical treatment such as an injection. An evacuation chamber is provided with an essentially rigid interface element through which a medical treatment can be administered to a selected skin region, one or more walls which are placeable on, or in the vicinity of, the skin region, an interior defined by the walls and by the interface element, and an opening at the bottom of the interior which is sealable by the skin region. A device generates a vacuum within the evacuation chamber interior to a level suitable for drawing the skin region through the opening towards, and in a compressing relation against, the interface element, to inhibit the transmission of a pain signal generated by pain receptors located within the skin region.

Abstract: A method and apparatus are disclosed for improving bodily safety during exposure to an eye hazardous monochromatic treatment light source by diverging the light, such as with a diffusing unit attached to the light source distal end so that the radiance of the light exiting the distal end is an eye safe level. At a first position of the light source distal end substantially in contact with an outer surface of a target, the energy density of an exit beam from the distal end is suitable for effecting a desired treatment, and at a second non-contact position of the distal end the exit beam energy density is significantly less than a value suitable for effecting the treatment. In an additional embodiment, the diverging or diffusing unit has a device for evacuating vapors or particles from the target.

Abstract: Method and apparatus for effecting a bloodless incision of soft tissue within the oral cavity. A standard laser is converted into an isotopic laser replacing the gas in the discharge tube of the standard laser with isotopic gas without replacing other constituents of the gas of the standard laser. The thickness of anti-reflection coating on the windows of the discharge tube is increased and the reflectivity of the reflectors is increased to a maximal value. The pulse duration of the laser is decreased and the converted laser directing to a desired target location of soft tissue within the oral cavity. The target location is at a penetration depth deep enough to avoid bleeding and distant enough from the soft tissue to minimize collateral damage. The converted laser fired to the target location at a wavelength and at an energy level suitable to effect the bloodless incision.
