Abstract:
In general, in one aspect, the invention features systems, including a photonic crystal fiber (120) including a core (210) extending along a waveguide axis and a dielectric confinement region (220) surrounding the cor e, the dielectric confinement region (220) being configured to guide radiation along the waveguide axis from an input end to an output end of the photonic crystal fiber (120). The systems also includes a handpiece (680) attached to the photonic crystal fiber (120), wherein the handpiece allows an operator t o control the orientation of the output end to direct the radiation to a targe t location of a patient.
Abstract:
In general, in one aspect, the invention features methods that include guiding radiation at a first wavelength, ?1, through a core of a photonic crystal fiber and guiding radiation at a second wavelength, ?2, through the photonic crystal fiber, wherein |? 1 - ? 2| > 100 nm.
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.
