    Abstract: A long pulse alexandrite laser for treating dermatological specimens is disclosed. The use of alexandrite allows operation in the near-infrared, specifically in a 50 nm range surrounding 755. Infrared in this range allows good penetration while still achieving an acceptable ratio of hemoglobin to melanin absorption. In operation, the laser generates pulses having a durations between 5 and 100 msec and fluences between 10 and 50 J/cm . A light delivery system is provided that transmits the laser light output pulse to dermatological targets of a patient. The invention is also directed to a hair removal system. Here, it is desirable to use an index-matching application on the skin sections to be treated, and a visual indicator is thermo- or photo-responsive or otherwise responsive to the laser light pulse to generate a visible change. This provides the operator with a record of those parts of the skin that have already been treated. Finally, the invention is directed to a combined sclerotherapy and light treatment method and kit for unwanted veins. Substantially increased success, in the range of 90-100 % has been achieved by implementing a dwell time of between 12 hours and 6 months between the light-based therapy and the sclerotherapy. Preferably, the light-based therapy is performed before the sclerotherapy. Success can be achieved by performing the sclerotherapy followed by the light-based therapy after the dwell time, however.

    Abstract: Methods and apparatus for treatment, such as skin rejuvenation treatment, use non-uniform laser radiation. A high-intensity portion of the laser radiation causes collagen destruction and shrinkage within select portions of the treatment area, while a lower-intensity portion of the radiation causes fibroblast stimulation leading to collagen production across other portions of the treatment area. An output beam from a laser source, such as an Nd:YAG laser, is coupled into an optical system that modifies the beam to provide a large-diameter beam having a nonuniform energy profile, comprised of a plurality of high-intensity zones surrounded by lower-intensity zones within the treatment beam. The higher-intensity zones heat select portions of the target tissue to temperatures sufficient for a first treatment (e.g. collagen shrinkage), while the lower-intensity zones provide sufficient energy for a second treatment (e.g. stimulated collagen production). A large area of tissue, preferably 7-10 mm in diameter, can be treated simultaneously, while minimizing the risk of burning or other damage to the skin. In one embodiment, the invention uses a fiber bundle to provide a non-uniform energy output beam, hi another embodiment, the invention uses a diffractive lens array to produce the non-uniform output beam. A cooling system can also be integrated with the laser treatment system. A pulse light source can also be integrated with the laser treatment system in a combined skin rejuvenation therapy.

    Abstract: A device and related method for the removal of subcutaneous adipose layers comprises a laser source; an optical fiber for conveying a laser beam emitted by the laser source; and a hollow cannula for guiding the fiber to the subcutaneous treatment area. The cannula has a curved portion at its distal end, where the curved portion can be shaped to roughly conform to the contour of the patient's body structure. In this way, laser energy from the fiber, applied to the adipose layers, is generally directed away from the lower dermis of the patient, minimizing the risk of non-reversible damage to the dermis, including skin necrosis. In another embodiment, the optical fiber is a side-firing fiber that directs the laser energy away from the dermis. In other embodiments, a radiation detector, such as a thermal or optical sensor, monitors the temperature at the surface of the skin above the treatment area to warn the operator of harmful temperatures in the lower dermis. In another embodiment, a temperature sensitive material is applied to the surface of the skin above the treatment area to warn of harmful dermal temperatures. In another embodiment, a cooling mechanism cools the surface of the skin above the treatment area to prevent damage to the dermis.
