Patent ID: 8691321

Claim:
A method for fabricating a cardiovascular expandable scaffold comprising: blending a polymer composition comprising a crystallizable composition comprising a base polymer of poly L-lactide, and/or poly D-lactide, and/or poly L-lactide-co-PEG, and/or poly D-lactide-co-PEG, linked with modifying copolymers comprising poly L (or D)-lactide-co-Tri-methylene-carbonate or poly L (or D)-lactide-co-ε-caprolactone in the form of block copolymers or as blocky random copolymers; molding said polymer composition to structurally configure said scaffold; coating said polymer scaffold with a pharmaceutical composition comprising a ligand; and cutting said scaffold to form desired patterns; wherein the polymer scaffold is configured in the form of a continuously interconnected scaffold of struts which is crystallizable when stretched by expansion and wherein the polymer of poly L-lactide and poly D-lactide form a racemate-type cross-moiety crystallization.
