Abstract
An apparatus to treat a patient, the apparatus comprises a carrier having a proximal end and a distal end, an optical fiber to couple to a light source, a fluid delivery element comprising a nozzle having an orifice on the distal end, and an alignment structure to align the optical fiber with the orifice. A distance extends between the alignment structure and the orifice, such that the light beam emitted from the optical fiber diverges so as to allow energy transmission and fluid flow through the orifice. In some embodiments, the apparatus to ablate tissue comprises a source of pressurized fluid, and the nozzle is coupled to the source of pressurized fluid to release a fluid stream.

An apparatus to treat a patient, the apparatus comprising:
- a carrier having a proximal end and a distal end;
- an optical fiber configured to couple to a light source;
- a fluid delivery device comprising a nozzle with an orifice on the distal end;
- and
- an alignment structure having a radius of curvature to align the optical fiber with the orifice with a bend in the optical fiber relative to the carrier along the radius of curvature,
- wherein the alignment structure comprises an alignment orifice axially aligned with the orifice, the alignment orifice and the orifice of the fluid delivery device being coaxial relative to one another and spaced apart an axial distance relative to one another to allow energy transmission and fluid flow through the orifice.
