摘要：A method and apparatus for treating in situ biologic tissue include identifying apatient with a condition susceptible to treatment by forming a lesion in the tissue andaccessing a surface of the tissue. A lesion formation tool is positioned against theaccessed surface. The tool includes an optical fiber for guiding a coherent waveform of a
selected wavelength to a fiber tip for discharge of light energy from the fiber tip. Thewavelength is selected for the light energy to penetrate a full thickness of the tissue toform a volume of necrosed tissue through the thickness of the tissue. The tool furtherincludes a guide tip coupled to the fiber tip. The guide tip is adapted to have a dischargebore aligned with the fiber tip to define an unobstructed light pathway from the fiber tipto the tissue surface. The guide tip is further adapted to be placed against the tissuesurface with the guide tip slidable along the tissue surface in atraumatic sliding
engagement with the discharge bore opposing the tissue surface. The lesion formationtool is manipulated to draw the guide tip over the tissue surface in a pathway whilemaintaining the discharge bore opposing the tissue surface to form a transmural lesion inthe tissue extending a length of the pathway.
