Proven Material

Unique biosynthetic scaffold designed to facilitate tissue generation.1

Strength and flexibility

The only staple line reinforcement material with trimethylene carbonate (TMC) to help maintain the strength with increased conformability.2

Infiltration to enable vascularization

Porous, 3D microstructure facilitates new vascularized soft tissue ingrowth.1

Minimal inflammation

Compared with similar materials it has shown minimal tissue inflammatory response.2,4-5

Unique bioabsorbable polymer

Serving as a scaffold, GORE® SEAMGUARD® Reinforcement successfully guides the regeneration of favorable Type 1 collagen while gradually absorbing within six to seven months.1-2

Material thickness

Thin, conformable and compressible.

Consistent 0.4 mm average total thickness allowing for even pressure distribution over the tissue while minimizing impact on staple formation. The composition of GORE® SEAMGUARD® Reinforcement allows for the thickness to compress when more force is applied.3

0.2mm thick per side

Holds and protects

Strengthens staple lines with minimal inflammation.

Made with a synthetic buttressing material engineered to reduce perioperative leaks and bleeding.7 Compared with similar materials it has shown minimal tissue inflammatory response.2,4-5
