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.
