Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61L 1700

US Classification:

606230, 427 231

Abstract:

The present invention discloses a process for producing a braided suture having an improved knot strength comprising heating a braided suture coated with a low molecular weight biocompatible polymer to a temperature sufficient to melt the low molecular weight biocompatible polymer for a time sufficient to allow the low molecular polymer to be redistributed into the interstices of the braided suture thereby providing a coated braided suture with an improved knot tensile strength. Also disclosed is the coated braided suture having a low molecular weight polymer optimally dispersed throughout the braided sutures cross-section.

International Classification:

A61F 2/02

US Classification:

623 2372, 606151

Abstract:

An implantable prosthesis for repairing or reinforcing a tissue or muscle wall defect including a first composite structure including at least one layer of a non-absorbable material is disclosed. The first composite structure has a central portion sized and shaped to cover at least a portion of the tissue or muscle wall defect, and has an outer periphery. The prosthesis further includes a second structure having a reinforced central region and an outer peripheral edge, a reinforcing element positioned between the first and second structures, and having an outer periphery and a stiffness greater than that of the first and second structures, and at least one pulling element coupled to the reinforced central region of the second structure. The second structure is coupled to the first structure substantially only at their respective peripheries.
