Abstract
A method and apparatus for sealing and/or grasping lesions or incisions of luminal tissue is provided. The apparatus has a generally tubular assembly with portions which expand away from each other. The apparatus is inserted into the lumen of a tissue and placed adjacent the area to be sealed. The portions expand to contact the inner wall of the luminal tissue. Energy is delivered with a media through the expanded tubular assembly to heat the tissue to a nondestructive range where the tissue forms a denatured proteinaceous substance. The media delivering the energy is rotated in the expanded tubular assembly to heat different areas of the tissue without moving the tubular assembly itself. In an alternate embodiment of the invention, tubular portions of the assembly are provided which have side edges that slide toward and away from each other. The assembly is placed in the lumen and the tissue edges are inserted into the assembly between the side edge. The side edges then slide toward each other to hold the tissue edges in tight approximation while energy sufficient to form a denatured proteinaceous substance is applied to the tissue.
