Filed:

Dec 15, 2000

Appl. No.:

09/737721

Inventors:

Scott Davenport - Half Moon Bay CA
Steven C. Murray - Santa Cruz CA
Tony Coleman - San Jose CA

Assignee:

Laserscope - San Jose CA

International Classification:

A61B 1818

US Classification:

606 3, 606 2, 606 15, 600 2, 607 89, 607100

Abstract:

Methods are provided for treating prostate glands or other targeted soft tissue using a solid-state laser. The laser can be operated to generate a pulsed output beam having pulse durations of between 0. 1 and 500 milliseconds. The output beam is delivered to the targeted tissue through an optical fiber, preferably terminating in a side-firing probe or diffusing tip. By operating the laser in a long-duration pulse mode, charring of the targeted tissue is initiated quickly, thereby increasing ablation rates and reducing overall procedure time.

Abstract:

A method for photoselective vaporization of prostate tissue includes delivering laser radiation to the treatment area on the tissue, via an optical fiber for example, wherein the laser radiation has a wavelength and irradiance in the treatment area on the surface of the tissue sufficient because vaporization of a substantially greater volume of tissue than a volume of residual coagulated tissue caused by the laser radiation. The laser radiation is generated using a neodymium doped solid-state laser, including optics producing a second or higher harmonic output with greater than 60 watts average output power. The delivered laser radiation has a wavelength for example in a range of about 200 nm to about 650 nm, and has an average irradiance in the treatment area greater than about 10 kilowatts/cm, in a spot size of at least 0. 05 mm.
