Abstract
The present invention relates to a monofilament suture prepared by co-extruding polymers having different Young's moduli and to a process for preparing the same. The suture is prepared in such a form that a polymer having a high Young's modulus surrounds a polymer having a low Young's modulus. The monofilament suture prepared by the present invention has excellent knot security, flexibility and/or knot strength.
Claims10
A monofilament suture, having improved knot security and flexibility, comprising a first absorbable polymer and a second absorbable polymer having a Young's modulus lower than the Young's modulus of the first polymer said first polymer is co-extruded with said second polymer forming a sea/island type suture comprising a plurality of islands wherein the first polymer is the sea component and the second polymer is the island component, and wherein the Young's modulus of the first polymer and the second polymer is 3.0 GPa or less, and wherein the difference of the Young's modulus between the first polymer and the second polymer is 0.3 GPa or more.
