ABSTRACT:
A laser surgery apparatus including a contact tip comprising an input face having a surface for receiving laser energy from an optical waveguide directed along an axis of propagation. The surface is inclined relative to the axis of propagation such that an angle of incidence between the laser light and the surface is approximately equal to Brewster's angle. Another aspect of the invention includes coating a portion of the tip body with a coating that is reflective to the laser energy. One preferred embodiment comprises a tip body coated with a single coating consisting essentially of a material which is biologically compatible with tissue to prevent generation of a toxic tissue response. A further aspect of the invention includes a tip configuration having a generally conical exterior with a substantially flat surface disposed obliquely to a core axis of the tip body. An additional feature on the invention includes a shield to protect tissue adjacent to the shield from undesired thermal damage by preventing the transfer of thermal energy through the shield.
