Abstract:
1. A method of treating benign prostatic hyperplasia of a prostate comprising the steps of: providing a medical laser device having two laser sources therein, said laser sources emitting two wavelengths of radiation; selecting a combination of said wavelengths to effect a desired treatment of selected prostatic tissue, wherein the first wavelength provides a coagulating effecting the prostatic tissue, and the second wavelength causes ablation of prostatic tissue; delivering said radiation to said selective prostatic tissue by means of an optical fiber having a fiber core and at least one cladding layer; positioning an distal end of said optical fiber system in or near said selected prostatic tissue; and irradiating said selected prostate tissue of said prostate with said radiation, wherein said first wavelength is transmitted through the at least one cladding layer and said second wavelength is transmitted through said fiber core, wherein said first wavelength transmitted through the at least one cladding layer is shorter than said second wavelength transmitted through said fiber core.
