Abstract
Methods and apparatus for retracting the dura away from a cutting tool during a laminectomy procedure. The method includes inserting a memory shape surgical sponge (patty) into an initial epidural space between the dura and the tool used to decompress (e.g., drill) the lamina. As the lamina is further decompressed, the patty tends to spring back toward its nominal position, urging the dura away from the decompression and isolating the dura from the drill.
