Abstract
Official abstract text for this publication.
The present invention is directed to a novel poly(diol citrates)-based bioceramic composite materials created using completely biodegradable and a bioceramic material polymers that may be used in implantable devices. More specifically, the specification describes methods and compositions for making and using bioceramic composites comprised of citric acid copolymers and a bioceramic material.
First claim
Opening claim text (preview).
We claim: 1. A composition comprising a composite of: a) a polyester comprising one or more linear aliphatic diol monomers and a citric acid monomer; and b) a bioceramic used for implantable tissue devices, wherein said composition comprises said bioceramic in an amount of 55 wt % or greater. 2. The composition of claim 1 , wherein the linear aliphatic diol monomer comprises between about 2 and about 20 carbons. 3. The composition of c…
