摘要：
A multi-wavelength laser apparatus and methods for laser ablation of tissue are described. The apparatus and methods utilize a laser source emitting at two or more wavelengths coupled to a fiberoptic laser delivery device and a laser driver and control system with features for protection of the laser delivery device, the patient, the operator and other components of the laser treatment system. A fiber tip protection system limits damage to the fiberoptic laser delivery device, thereby allowing the multi-wavelength laser to be operated in a tissue contact mode. The invention, which has broad medical and industrial applications, is described in relation to a method for treatment of benign prostatic hyperplasia (BPH) by contact laser ablation of the prostate (C-LAP) using a technique of touch and pullback laser ablation of the prostate (TapLAP).
