Patent ID: 8343530

Claim:
An implantable medical device comprising a stent composed of a scaffolding including a pattern of interconnecting struts fabricated from a bioceramic/polymer composite, the composite comprising: a continuous phase comprising a matrix copolymer of L-lactide and glycolide, a majority of the copolymer comprising L-lactide; and a discrete phase within the continuous phase, the discrete phase comprising a modifier polymer having discrete phase segments, the discrete phase segments being immiscible with the matrix copolymer, the modifier polymer further comprising anchor segments that are miscible with the matrix copolymer, wherein the modifier polymer is a biodegradable polymer, wherein a plurality of bioceramic particles are dispersed within the continuous and/or the discrete phase, wherein the bioceramic/polymer composite is between 0.5% and 2% bioceramic particles by weight as compared to the polymers of the composite.
