Abstract
An endoscopic light delivery system for delivering light to tissue includes a laser source for generating light. Fiber optics are optically coupled to the laser source for conveying the light generated by the laser source. A focusing surface is formed at an end of the fiber optics. The focusing surface of the fiber optics is shaped for redirecting light conveyed by the fiber optics in a direction lateral to the fiber optics for cutting tissue. A single optical fiber or a bundle of optical fiber can be used to transmit plural wavelengths of light for aiming cutting and coagulating.
