Abstract

A surgical staple line reinforcement is provided for use with a variety of surgical staplers to protect against tissue damage from surgical staples. The surgical staple line reinforcement is made up of a tubular structure of bio-implantable material with one or more stiffening members attached to or integrated within the tubular structure to resist, prevent or inhibit movement, rotation, or longitudinal compression of the tubular structure.

Claims

1. A staple line reinforcement comprising a tubular structure having at least one operative face proportioned to reinforce surgical staples at a surgical site and one or more stiffening members attached to or integrated with the tubular structure to resist, prevent, or inhibit movement, rotation, or longitudinal compression of the tubular structure comprising a means to allow separation of the face of the tubular structure away from a remainder of the tubular structure after insertion wherein said means comprise parallel lines of perforations to allow separation of the face from the tubular structure wherein the perforations are staggered relative to each other to resist longitudinal compression of the tubular structure.

2. The staple line reinforcement of claim 1 wherein the face comprises a thin compressible material and the stiffening member comprises a stiffer material which resists movement, rotation, or longitudinal compression of the tubular structure.

3. The staple line reinforcement of claim 2 wherein the face and stiffening member comprise different materials.

4. The staple line reinforcement of claim 1 further comprising a loop or tab to assist in separation of the face from the remainder of the tubular structure after insertion.
