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.
Claims26
A surgical article having knot security and improved knot repositioning characteritics, the article comprising a strand, the strand having a bioabsorbable coating, the coating comprising a random copolymer, from about 50 to 85 percent by weight of the copolymer consisting of linkages of formula (I):
- ##STR7## and the remaining linkages comprising at least one of the formulas (II) to (VIII):
- ##STR8##
A surgical suture or ligature comprising a bioabsorbable, multifilamentary strand manufactured from a polymer prepared from one or more monomers selected from the group consisting of glycolide, lactide, 1,3-dioxan-2-one and 1,4-dioxan-2-one, the strand having a bioabsorbable coating, the coating comprising a random copolymer, from about 65 to 85 percent by weight of the coating copolymer consisting of linkages of formula (I):
- ##STR11## and the remaining linkages comprising at least the formula (II):
- ##STR12## wherein the inherent viscosity of said copolymer is about 0.2 to 1.4 dl/g (0.5 g/dl in CHCl.sub.3, 30.degree. C.), and said coating comprises about 1/10 to 5 percent by weight of the coated suture or ligature.
