Abstract

The rate of degradation of polymers and polymer blends containing (poly) lactic acid can be increased and controlled by the inclusion of up to 10% (typically less than 1%) by weight of specific additives such as lauric acid or a derivative thereof such as the anhydride.

Claims (12)

1. An implantable, biodegradable medical device formed from a homogeneous polymer blend comprising a lactic acid polymer in admixture, in an amount of not more than 10%
by weight of the polymer blend, with an additive which is an acid or a derivative thereof selected from the group consisting of hexanoic acid, octanoic acid, decanoic acid, lauric acid, myristic acid, crotonic acid, 4-pentenoic acid,
2-hexenoic acid, undecylenic acid, petroselenic acid, oleic acid, erucic acid, 2,4-hexadienoic acid, linoleic acid, linolenic acid, benzoic acid, hydrocinnamic acid, 4-isopropylbenzoic acid, ibuprofen, ricinoleic acid, adipic acid, suberic acid, phthalic acid, 2-bromolauric acid, 2,4-hydroxydodecanoic acid, monobutyrin, 2-hexyldecanoic acid, 2-butyloctanoic acid, 2-ethylhexanoic acid, 2-methylvaleric acid, 3-methylvaleric acid, 4-methylvaleric acid, 2-ethylbutyric acid, trans-beta-hydromuconic acid, isovaleric anhydride, hexanoic anhydride, decanoic anhydride, lauric anhydride, myristic anhydride, 4-pentenoic anhydride, oleic anhydride, linoleic anhydride, benzoic anhydride, poly(azelaic anhydride), 2-octen-1-yl succinic anhydride and phthalic anhydride.
2.

8. A device as claimed in any one of the previous claims wherein the polymer blend is the matrix component of a composite material from which the device is formed.
9. A device as claimed in any one of the previous claims in the form of a suture, suture anchor, soft tissue anchor, interference screw, tissue engineering scaffold, maxial-facial plate, or a fracture fixation plate or rod.
10. A polymer blend, useful for the manufacture of biodegradable medical devices comprising polylactic acid in admixture with an additive in an amount of not more than 10% by weight of the blend of at least one of hexanoic acid, octanoic acid, decanoic acid, lauric acid, myristic acid, crotonic acid, 4-pentenoic acid, 2-hexenoic acid, undecylenic acid, petroselenic acid, oleic acid, erucic acid, 2,4-hexadienoic acid, linoleic acid, linolenic acid, benzoic acid, hydrocinnamic acid, 4-isopropylbenzoic acid, ibuprofen, ricinoleic acid, adipic acid, suberic acid, phthalic acid, 2-bromolauric acid, 2,4-hydroxydodecanoic acid, monobutyrin, 2-hexyldecanoic acid, 2-butyloctanoic acid, 2-ethylhexanoic acid, 2-methylvaleric acid, 3-methylvaleric acid, 4-methylvaleric acid, 2-ethylbutyric acid, trans-beta-hydromuconic acid, isovaleric anhydride, hexanoic anhydride, decanoic anhydride, lauric anhydride, myristic anhydride, 4-pentenoic anhydride, oleic anhydride, linoleic anhydride, benzoic anhydride, poly(azelaic anhydride), 2-octen-1-yl succinic anhydride or phthalic anhydride.
11. A blend was claimed in claim 10 comprising not more than 5%
by weight of the additive.
12. A blend was claimed in claim 11 comprising no more than 2%
by weight of the additive.
