ABSTRACT:
An apparatus and method is disclosed for treating vascular lesions. In the preferred embodiment, an intracavity, frequency doubled Nd:YAG laser is used to generate output pulses having a duration of 0.5 to 10.0 milliseconds. This laser output is used to irradiate the lesions. The laser energy is absorbed in the blood of the vein, causing it to coagulate and collapse. The long pulse duration helps to minimize bleeding while controlling thermal damage to surrounding tissue.
