ABSTRACT:
A laser medical probe adapted for direct contact with, or insertion into, tissue undergoing laser treatment. The probe includes a laser energy transmissive surface for emitting radiation from the probe. The probe surface includes a layer of laser transmissive particles for diffusing laser energy passing therethrough and an affixing material for affixing the particles to the probe surface. Laser energy emitted from the surface may be coupled into the particles and irregularly refracted and reflected thereby causing a wide laser energy radiation profile. The affixing material and the particles form a tissue contact surface for directly contacting the tissue undergoing treatment. A substantial number of the particles partially extend from the affixing material. The resultant tissue contact surface is rough. The affixing material may be a ceramic bonding agent.
