  • Publication number: 20140221989
    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/cm2, in a spot size of at least 0.05 mm2.

  • Patent number: 7837091
    Abstract: A method for operating a laser system for a medical procedure, or a similar system, comprises detecting presence of a portable memory device like a smart card coupled to the laser system, and reading data on the portable memory device usable to identify an associated delivery device. An identifier is read from the associated delivery device after it is coupled to the laser. A process is executed to verify the configuration including matching the identifier read from delivery device with the delivery device associated with the portable memory device, verifying that the portable memory device includes a data structure adapted for storage of an event log, and enabling delivery of laser energy if said authenticating and said verifying are successful. A kit comprising a delivery device and a portable memory device supporting the process is provided to users of the laser system.

  • Patent number: 7083610
    Abstract: A device for irradiating tissue includes a fluorescent element for receiving pump radiation and responsively emitting radiation having different spectral characteristics than the pump radiation. A redirector receives emitted radiation promulgated in a direction away from a tissue target and redirects the radiation toward the target. The pump radiation may be supplied, for example, by a flashlamp or frequency-doubled neodymium-doped laser. Use of the device provides an inexpensive and effective alternative to conventional dye laser-based systems for various medical therapies, including treatment of vascular and pigmented lesions, tattoo and hair removal, and photodynamic therapy (PDT).

  • Patent number: 6554824
    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.
