Description

The performance enhancement of barbed sutures via changes in barged geometry was studied. The straight-pull tensile strengths and barb geometries of the barbed sutures were also determined. A barbed structure can exhibit equal or better biomechanical performance, when fabricated with specific barb geometry parameters, than a knotted predicate suture in both tensile strength and wound holding capacity. The results show that a barbed suture can perform equivalently to its same-size conventional counterpart even with a lower tensile strength.
