A suture coating comprising a copolymer having about 60 to 80 weight percent of .beta.-hydroxybutyrate linkages is disclosed. The remaining linkages can be at least .beta.-hydroxyvalerate. In one embodiment, the coating is the copolymer combined with a stearoyl lactylate having the formula: ##STR1## wherein X is at least two, and R is an alkaine-earth metal.

Bioabsorbable coating for a surgical device

A bioabsorbable coating for a surgical suture or ligature is disclosed. The coating is manufactured from a diblock or a triblock copolymer.

Bioabsorbable surgical suture coating

A bioabsorbable coating for a surgical article comprises a copolymer manufactured from the monomer caprolactone and at least one other copolymerizable monomer. The surgical article can be a bioabsorbable suture or ligature.

Bioabsorbable coating for a surgical article

The invention discloses a surgical filament having a coating comprising a compound of the formula: ##STR1## wherein x is at least 2, R' is selected from the group consisting of an alkaline-earth metal ion or radical, and R' is an alkyl group having at least 12 carbon atoms in the backbone. In a specific embodiment, the surgical filament is a bioabsorbable suture or ligature manufactured from a polymer containing at least one glycolic acid ester linkage.

Surgical filament coating

A surgical suture coating comprising a random copolymer is disclosed. The copolymer has about 25 to 75 weight percent of glycolic acid ester linkages. The remaining linkages comprise at least trimethylene carbonate. The copolymer has a glass transition temperature at or below ambient temperature.
