Abstract
Abstract A surgical suture having a coating thereon of a block poly(ether-co-amide), and a method for improving the knot tiedown performance of a suture by first coating a block poly(ether-co-amide) solution of a block poly(ether-co-amide) onto the surface of the suture and then removing the solvent from the coated suture.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
36 words
A suture wherein the surface thereof is coated with an amount of a block poly(ether-co-amide) effective to improve the knot tiedown performance of the coated suture relative to the knot tiedown performance of the uncoated suture.
Claim 2
Dependent Claim
36 words
A suture wherein the surface thereof is coated with an amount of a block poly(ether-co-amide) effective to improve the knot tiedown performance of the coated suture relative to the knot tiedown performance of the uncoated suture.
Claim 3
Dependent Claim
23 words
The suture of claim 1 wherein the amount of polyether in the block poly(ether-co-amide) is from about 25 to about 80 weight percent.
Claim 4
Dependent Claim
22 words
The suture of claim 1 or claim 2 wherein the polyether blocks of the block poly(ether-co-amide) contain repeating units of polytetramethylene oxide.
Claim 5
Dependent Claim
20 words
The suture of any preceding claim wherein the polyamide blocks of the block poly(ether-co-amide) contain repeating units of nylon 12.
Claim 6
Dependent Claim
23 words
The suture of any preceding claim wherein the block poly(ether-co-amide) is a copolymer of a low molecular weight block poly(ether-co-amide) and a lactone.
Claim 7
Dependent Claim
34 words
The suture of any preceding claim wherein the amount of block poly(ether-co-amide) coated onto the surface of the suture ranges between about 0.05 to about 10 percent of the weight of the coated suture.
Claim 8
Dependent Claim
21 words
The suture of any preceding claim wherein the molecular weight of the block poly(ether-co-amide) is between about 45,000 and about 95,000.
Claim 9
Dependent Claim
22 words
The suture of any preceding claim wherein the suture is a monofilament or multifilament suture with or without one or more needles.
Claim 10
Dependent Claim
12 words
The suture of claim 8 wherein the suture is a multifilament suture.
Claim 11
Dependent Claim
13 words
The suture of claim 9 wherein the multifilament suture is an nonabsorbable suture.
Claim 12
Dependent Claim
12 words
The suture of any preceding claim wherein the suture is a polyester.
Claim 13
Dependent Claim
11 words
The suture of claim 11 wherein the polyester is polyethylene teraphthalate.
Claim 14
Independent Claim
47 words
A method of improving the knot tiedown performance of a suture comprising the steps of: a) coating the surface of the suture with an effective amount of a solution of a block poly(ether-co-amide) in an organic solvent, and then b) removing the solvent from the coated suture.
Claim 15
Independent Claim
47 words
A method of improving the knot tiedown performance of a suture comprising the steps of: a) coating the surface of the suture with an effective amount of a solution of a block poly(ether-co-amide) in an organic solvent, and then b) removing the solvent from the coated suture.
Claim 16
Dependent Claim
39 words
The method of claim 13 wherein the solution of block poly(ether-co-amide) is a solution of between about 0.2 to about 6.0 weight percent of block poly(ether-co-amide) in 2,2,2-trifluoroethanol or in a mixture of solvents such as 2,2,2-trifluoroethanol and toluene.
Claim 17
Dependent Claim
20 words
The method of claim 13 or claim 14 wherein the solvent is removed by drying the coated suture in air.
Claim 18
Independent Claim
39 words
The method of claims 13, 14 or 15 wherein the solution of block poly(ether-co-amide) is a solution of between about 0.2 to about 6.0 weight percent of block poly(ether-co-amide) in 2,2,2-trifluoroethanol or in a mixture of 2,2,2-trifluoroethanol and toluene.
Claim 19
Independent Claim
20 words
The method of any one of claims 13 to 16 wherein the coated suture is dried at an elevated temperature.
