Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
41 words
A suture exhibiting an improved tie-down performance and maintaining good knot security when tied, comprising braided synthetic fibrous sutures coated with a coating composition for lubricating the suture, the fibers of the suture having crimps for providing texture to the suture.
Claim 2
Dependent Claim
41 words
A suture exhibiting an improved tie-down performance and maintaining good knot security when tied, comprising braided synthetic fibrous sutures coated with a coating composition for lubricating the suture, the fibers of the suture having crimps for providing texture to the suture.
Claim 3
Dependent Claim
45 words
A suture according to claim 1 wherein said suture exhibits one-third less of a roughness value of tie-down performance than that of an uncoated suture and also exhibits an equivalent or improved knot security when tied in place than that for an uncoated, textured suture.
Claim 4
Dependent Claim
42 words
A suture according to claim 1 wherein said coating composition is selected from the group consisting of sucrose fatty acid ester, beeswax, a mixture of stearic acid and copolymers of glycolide and lactide having a low degree of polymerization and paraffin wax.
Claim 5
Dependent Claim
29 words
A suture according to claim 1 wherein said suture comprises a synthetic polymer selected from the group consisting of polyglycolide, copolymers of glycolide and lactide, aromatic polyester, and nylon.
