A medical laser probe for contact laser surgery wherein a surgical incision, for example, is made by direct and indirect laser heating of the tissue. Direct heating is achieved in the conventional manner by direct laser irradiation of the subject tissue. Indirect heating is achieved through the use of a probe tip specially coated with infrared absorbing material. This material serves to partially absorb and partially transmit the laser energy. The absorbed laser energy heats the probe tip thereby facilitating tissue vaporization when the probe is brought into contact with the tissue. The transmitted laser energy vaporizes the tissue by the conventional irradiation thereof. The tip surface is roughened prior to application of the infrared material to enhance adhesion while an optically transparent material is placed over the tip to preclude material damage or erosion during normal tip use.
A medical laser probe for conveying laser energy from the output end of an optical laser waveguide to a tissue undergoing laser treatment, the probe comprising laser transmissive material having a laser energy input region for receiving laser energy from an optical waveguide and a laser energy radiation surface, the radiation surface defining a generally non-planar contour, the laser energy from the input region being propagated through the probe transmissive material to be incident on the probe radiation surface;
