Abstract
A surgical stapler comprising a first jaw comprising a first bioabsorbable matrix and a second jaw comprising a second bioabsorbable matrix is disclosed. At least one of the first jaw and the second jaw is moveable between an open position and a closed position to clamp tissue between the first bioabsorbable matrix and the second bioabsorbable matrix. At least one of the first bioabsorbable matrix and the second bioabsorbable matrix comprises a plurality of layers including a fibrous layer. The fibrous layer comprises a plurality of deformable structures each having an equilibrium configuration. The deformable structures are expandable and compressible from the equilibrium configurations to reshape the fibrous layer and accommodate for variations in tissue thickness when tissue is clamped between the first bioabsorbable matrix and the second bioabsorbable matrix.
