First Claim
Patent Images
1. A suture comprising:
- a filament made from a synthetic, non-absorbable polymer composition; and
a liquid coating, the coating comprising a fray-reducing amount of a non-drying oil selected from the group consisting of castor oil and mineral oil, wherein the coating remains a liquid after application to the suture.

Abstract
Sutures formed from one or more filaments are coated with an oil, such as for example, mineral oil or castor oil. The sutures exhibit good durability as reflected by fray resistance.
