Claim Text:
1. A catheter comprising: a housing having a proximal end, a distal end, a liquid infusion port, and an inner lumen extending from the liquid infusion port to the distal end of the housing, wherein the inner lumen is configured to receive fluid introduced into the liquid infusion port, wherein the distal end of the housing comprises a completely solid tubular wall; a bundle of optical fibers positioned within the inner lumen, the bundle of optical fibers comprising a distal end, wherein the bundle of optical fibers is capable of emitting light in a uniform direction; and a deflecting member positioned within the inner lumen distal to the distal end of the bundle of optical fibers, the deflecting member comprising: a proximal end; a distal end having a diameter greater than the proximal end; a tapered region, the tapered region extending from the proximal end to the deflecting member to the distal end of the deflecting member such that when fluid and light contacts the tapered region, at least a portion of the fluid and light is diverted from a substantially uniform direction to produce a fluid and light pattern that is larger than a fluid and light pattern produced without the fluid diversion at the distal end of the housing.
