Abstract

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.
