Abstract

Small diameter tools are provided, and methods of use described, to facilitate less invasive surgical procedures employing laser beams. Such tools include distal tips that enhance the precise placement of optical waveguides, as well as enable cutting and dissecting procedures. A rotary coupler allows precise control of flexible conduits in which waveguides may be disposed. Waveguide tips with conical features protect waveguide ends and allow unobstructed propagation of the laser beam out of the waveguide. A preferentially bending jacket for waveguides may be used to control an orientation of a waveguide disposed therein. Surgical waveguide assemblies may include various combinations of these components.
