Abstract

The system and method of delivery of laser radiation comprises a flexible hollow waveguide connectable at a first end to a low power laser source, such as a CO.sub.2 laser, a rigid hollow waveguide having a proximal end and a distal end, a coupler for coupling the second end of the flexible hollow waveguide to the proximal end of the rigid hollow waveguide and a diamond tip partially disposed within and extending from the distal end of the rigid waveguide. The diamond tip has an entrance face for receiving laser radiation and at least one exit face for transmitting laser radiation toward an area of biological tissue. The exit end of the diamond tip may be flat, parallel to the entrance face, curved, to act as a lens providing a focusing function, or beveled, to create one or more blade edges to limit the point(s) of exit of the laser radiation and to provide a cutting edge which may be used in combination with the radiation to simultaneously create and photocoagulate the tissue at an incision.
