The Pressfit® anal fistula plug is made of deantigenated porcine dermis through an enzymatic treatment at low temperature. This process preserves the integrity of the extracellular matrix that acts as a natural scaffold for the formation of new tissue.
Pressfit® anal fistula plug has a wedge “solid” design. Its geometric shape prevents axial displacement and rotation thanks to the presence of sharp edges. Its solid shape allows intimate contact with the fistula.
Primary stability and intimate contact are biomechanical conditions necessary for the cell invasion in the collagen matrix and the tissue remodelling.
