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.
Claims29
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
- 3
- where R is an aliphatic group and n is an integer from 2 to about 10, preferably 4 to 6.
A method for making a coated suture comprising:
- providing a suture comprising at least one filament having a surface;
- and
- applying a coating to at least a portion of the surface of the at least one filament of the suture by a plasma polymerization process of a hydrocyclosiloxane monomer of the general formula
- 5
- where R is an aliphatic group and n is an integer from 2 to about 10, preferably 4 to 6.

A suture comprising:
- at least one filament;
- and
- a coating formed on at least a portion of a surface of the at least one filament by a plasma polymerization process wherein a polymer coating is formed on the filament surface from a hydrocyclosiloxane monomer of the general formula
- 7
- where R is an aliphatic group and n is an integer from 2 to about 10, preferably 4 to 6.
