Abstract

A device/system and a method of treating enlarged prostate and other urologic abnormalities are presented. A combined treatment is performed with several interstitial coagulating probes and an ablating fiber. Tissue vaporization is minimized by the denaturalizing effect of interstitial coagulative fibers. In a single device, multiple delivery systems achieve optimal tissue ablation/coagulation; a non-laser source like microwave energy coagulates tissue and a laser source ablates tissue. Another device comprises two or more laser sources with adjustable wavelengths controllable by physician as to ablative, coagulative, and tissue penetration needs. Continuous, semi-continuous, pulsed wave, or combinations are useful. In another embodiment, optical fiber has a central core for transmitting laser radiation, and a cladding layer about the core that may further transmit other laser radiation of a different or a same wavelength as the core. Fibers may have a side-firing distal end, a radial firing end, or an off-axis firing end. Feedback controls can be used. In general coagulative irradiation can use a radiofrequency or other radiant thermal source.
