A fiber tip fluid output device is provided for holding a fiber tip in an
electromagnetic energy cutting apparatus and for directing water
particles over a radiation delivery end of the fiber tip. The fiber tip
fluid output device includes a generally cylindrical body having an outer
surface, a proximal end, a distal end, and a lumen extending between the
proximal end and the distal end. The lumen is sized and shaped to
accommodate a fiber tip therethrough so that the fiber tip extends
through the lumen from the proximal end to the distal end of the
generally cylindrical body. The fiber tip fluid output device further
includes a plurality of apertures extending around the generally
cylindrical body, with each of the apertures of the plurality of
apertures fluidly connecting the outer surface to the lumen. Fluid is
mixed around the cylindrical body, before entering the lumen through the
plurality of apertures for additional mixing. The mixed fluid is then
output from the lumen of the fiber tip fluid output device onto the fiber
tip, for subsequent interaction with electromagnetic energy in an
interaction zone above a target surface.
