TenaTac® has a unique surface modification created with high precision. The surface of the sponge is divided into over 1000 columns. This leads to a 10-fold increase in surface area, greatly increasing the interaction between the product and the underlying tissue. The flexible columns conform to the variations in tissue surface and act independently to resist shear forces that may dislodge a normal sponge in the peri-operative period.
TenaTac® becomes pliable when moist and compresses to 1-2mm depth.
