An endoscope for an optical fiber provides for inflow and outflow of irrigant. A telescope is included having a field of view directed into a working region. The endoscope defines a 'hooded region' with an extended, blunt tip. The optical fiber fits within the endoscope has a side or end firing tip with an emission surface. A guide element is adapted to movably support the optical fiber in a position spaced away from the working region, and limit lateral movement of the tip without preventing longitudinal and rotational movement. An irrigant flow arrangement operates to direct inflowing irrigant over the emission surface of the tip. The fiber is assembled with a fiber coupler, a handle, a fiber port cap, and a travel limiter fixed to the fiber at a predetermined distance from the tip. The travel limiter cooperates with the endoscope and the fiber port cap to limit longitudinal and rotational movement of the fiber.

Endoscope and optical fiber assembly

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.

A method for photoselective vaporization of uterine 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.
