Coated gut suture

摘要

A gut suture is coated with a bioabsorbable copolymer obtained by polymerizing a major amount of epsilon -caprolactone and a minor amount of at least one other copolymerizable monomer in the presence of polyhydric alcohol as initiator. The coated gut suture can be packaged in the absence of conventional tubing fluid, i.e., in the dry state, while at the same time retaining flexibility, pliability and resistance to fray. In an alternative embodiment, a gut suture is coated with a pre-coating composition prior to being coated with the bioabsorbable copolymer. <IMAGE>
