Abstract

A method for suturing a wound using a suture manufactured from polyamide ester having the reaction product of at least one molecular weight diols; at least one dicarboxylic acids and at least one polyoxyalkylene diimide diacid to create a wound closure.

Claims

1. A method of suturing a wound which comprises:

a) passing through tissue needled suture manufactured from a polyetherimide ester composition with comprises the reaction product of

i) at least one low molecular weight diol;

ii) at least one dicarboxylic acid; and

iii) at least one polyoxyalkylene diimide diacid;

to create wound closure; and

b) removing the needle from said suture.

2. The method of claim 1 wherein the polyetherimide ester comprises the reaction product of the reaction product of (a) 1,4-butanediol (b) dimethyl-terephthalate and (c) a polyoxyalkylene diimide diacid derived from trimellitic anhydride and a polyoxyalkylene diamine.

3. The method of claim 1 wherein the diol is selected from a member of the group consisting of a C₂ to C₁₅ cycloaliphatic diol, a C₂ to C₁₅ cycloaliphatic diol and mixtures thereof.

4. The method of claim 3 wherein the diol is 1,4 butane diol.

5. The method of claim 1 wherein the dicarboxylic acid is selected from a member of the group consisting of C₂ to C₁₆ aliphatic dicarboxylic adds, C₂ to C₁₆ cycloaliphatic dicarboxylic adds, C₆ to C₁₆ aromatic dicarboxylic acid, ester derivatives thereof and mixtures thereof.

6. The method of claim 1 wherein the dicarboxylic acid is dimethyl terephalate.

7. The method of claim 1 further comprising a member selected from the group consisting of stabilizers and at least one medico-surgically useful substance.

8. The method of claim 1 further comprising a human growth factor.

9. The method of claim 1 wherein the suture is a monofilament suture.

10. The method of claim 1 wherein the suture is a multifilament suture.

11. The method of claim 1 wherein the suture is a dyed suture.

12. The method of claim 2 wherein the polyetherimide composition comprises at least about 50 mole percent the reaction product of

a) 1,4 butanediol;

b) dimethyl terephthalate; and

c) a polyoxyalkylene diimide diacid.

13. The method of claim 2 wherein the polyetherimide ester composition comprises at least about 70 mole percent the reaction product of

a) 1,4 butanediol;

b) dimethyl terephthalate; and

c) a polyoxyalkylene diimide diacid.
