Abstract
An illumination device is described containing optical fibers that transmit electromagnetic energy from a source to a target. Additional optical fibers return reflected electromagnetic energy from the target. High-level electromagnetic energy can be used for cutting, reforming, or treating a surface. Low-level electromagnetic energy illuminates the surface.
Claims58
An illumination device having a proximal end and a distal end, the illumination device comprising:
- an elongate body having a flexible, non-rigid portion and a distally-disposed, inflexible, rigid portion;
- an output portion that is rotatable relative to the distally-disposed portion;
- a power fiber extending from the proximal end to the distal end;
- a plurality of first optical fibers disposed within the elongate body, concentrically arranged around the power fiber, and extending from the proximal end to the distal end, the plurality of first optical fibers being capable of receiving a first type of electromagnetic energy from the proximal end and of outputting the first type of electromagnetic energy at the distal end;
- and
- a plurality of second optical fibers concentrically arranged around the power fiber and extending from the proximal end to the distal end, the plurality of second optical fibers being capable of receiving a second type of electromagnetic energy from the distal end and of directing the second type of electromagnetic energy to the proximal end.
