Abstract:
1. An apparatus for treating biological tissue, comprising: a base unit, the base unit comprising an energy supply; a handpiece; an umbilicus having a first end configured to be coupled to the base unit and a second end configured to be coupled to the handpiece; a source of electromagnetic radiation, the source of electromagnetic radiation configured to receive energy from the energy supply and generate electromagnetic radiation; a waveguide configured to receive the electromagnetic radiation from the source, the waveguide comprising: an optical output element optically coupled to one of the first and second ends of the waveguide, wherein the fluorescent substance is configured to absorb the electromagnetic radiation from the source through the wall and generate fluorescent light in response to the electromagnetic radiation, wherein the waveguide is configured to guide the fluorescent light emitted by the fluorescent substance towards the optical output element by internally reflecting at least a portion of the fluorescent light, and wherein the optical output element is configured to direct the fluorescent light away from the waveguide; a fluid conduit in fluid communication with the waveguide's passage and configured to carry the fluorescent substance between the waveguide's passage and a fluid moving system, the fluid moving system adapted to move the fluorescent substance through the fluid conduit and the waveguide's passage; and a cooling system configured to cool the fluorescent substance.
