High molecular weight polylactide and polycaprolactone copolymer and blends for bioresorbable vascular scaffolds

A stent comprising:

• a bioresorbable polymer scaffold comprising a polymer formulation including a blend of polylactide (PLA) polymer and a PLA and polycaprolactone (PCL) copolymer,
• wherein the PLA polymer is poly(L-lactide) (PLLA) and the copolymer is 70/30 poly(L-lactide-co-caprolactone) random copolymer, wherein caprolactone units of the copolymer are 1 to 5 wt % of the blend,
• wherein the scaffold includes a plurality of interconnected struts,
• wherein a thickness of the struts is 80 to 100 microns and a width of the struts is 200 to 250 microns,
• wherein a number average molecular weight (Mn) of the blend is greater than 60 kDa, and
• wherein the scaffold has a crimped state and a deployed state and a radial strength of the scaffold when expanded from the crimped state to the deployed state in saline or bodily fluid at 37° C. is at least 650 mm Hg.
