TAWT Technique

TAWT (pronounced "taut") is a technique to help close the acute open abdomen and reconstructing chronic giant ventral hernias. TAWT helps achieve abdominal wall closure without components separation or bridging mesh and preserves the leading edge of the fascial borders for final closure.

TAWT utilizes the Wittmann Patch hook-and-loop sheets to apply constant isometric traction to both sides of the abdominal wall. The postulated mechanism is an isometric-traction-induced myofascial release that gradually lengthens the retracted oblique and latissimus muscles to recapture abdominal domain.

Suture retention plates enable lateral external attachment of underlay hook and loop sheets to the peritoneal surface of the abdominal wall.

To order, see the ordering instructions.
