Monomax is the unique suture in the market made of poly-4-hydroxibutyrate. Extra-long term absorption, Monomax loses its relative tensile strength slower than polydioxanone sutures (slower tensile strength degradation profile compared to polydioxanone sutures). Elasticity and elongation: Monomax elongates twice as much as polydioxanone sutures. Sizes available USP 2/0 (metric 3) up to USP 1 (metric 4). It degrades by hydrolysis and enzymatic reaction.
