Abstract
Tissue adhesions are inhibited by applying and immobilizing a solid preformed matrix material over a target region, such as a surgical site, in a first tissue surface. The matrix material may be any continuous solid material, such as a sheet or film. After applying the material to the target region, the material is immobilized by applying energy over at least a portion of the surface of the matrix material which causes the material to fuse to the underlying tissue. The matrix material is preferably bioabsorbable so that it is resorbed by the body over time. Suitable matrix materials include proteins, polysaccharrides, and synthetic polymers.
