  • Patent number: 10285758
    Abstract: Apparatus and methods are described for laser ablation of tissue. The apparatus and methods utilize a laser source 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. Advantageously, the laser source may utilize laser diodes operating at approximately 975 nm, 1470 nm, 1535 nm or 1870 nm wavelengths with a laser power output of at least 60 watts, preferably greater than 80 watts and most preferably 120-150 watts or higher. 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).

  • Publication number: 20150141969
    Abstract: 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).
