Abstract

A method and apparatus for applying optical or other thermal energy to tissue using a clamp (12). The energy is supplied at a frequency which biologically welds or fuses tissue. A material (30) that is transmissive to the energy treatment frequency is embedded in one or more jaws (18, 20) of the clamp (12) and engages the tissue during the tissue fusion process. The transmissive material (30) has a thickness selected to insure that the energy source is spaced at the proper distance from the tissue to that the tissue receives the proper amount of energy for sealing. The transmissive material (30) holds the tissue in the jaw to maintain the edges of the tissue in tight approximation. The energy may be coupled to the clamp by one or more optical fibers (54). These fibers (54) are recessed in or placed adjacent to the jaw at a specified distance from the surface of the transmissive material (30) and directs treatment energy through the transmissive material (30) to weld the edges of the tissue together.
