Abstract
Suture filaments coated by a plasma polymerization process exhibit a good balance of knot run down and knot security characteristics, superior tissue drag characteristics, and improved fray resistance.
Claims17
A method for improving the fray resistance of a suture comprising at least one filament, the method comprising:
- applying a coating to at least a portion of a surface of the at least one filament of the suture by a plasma polymerization process of a hydrocyclosiloxane monomer of the general formula
- where R is an aliphatic group and n is an integer from 2 to about 10,
- wherein the coating improves the fray resistance of the suture.
