Patent ID: 8778375

Claim:
A coating comprising an amorphous poly(D,L-lactide) (PDLLA) having a degree of crystallinity of 10% or below and an additional biocompatible polymer, wherein the PDLLA is not made from a 50/50 blend of L,L-lactide and D,D-lactide, wherein the amorphous PDLLA is poly(meso-D,L-lactide) (meso-DLPLA), racemic poly(D,L-lactide) (racemic-DLPLA), or combination thereof, wherein the coating further comprises a syndiotactic polylactide (LPLA), and wherein the additional biocompatible polymer is selected from the group consisting of polymers and copolymers of 3-hydroxypropanoate, 3-hydroxyhexanoate, 3-hydroxyheptanoate, 3-hydroxyoctanoate, 4-hydroxyhexanote, 4-hydroxyheptanoate, and 4-hydroxyoctanoate; poly(tyrosine carbonates); poly(tyrosine ester); polyphosphoester; polyphosphoester urethane; polycyanoacrylates; poly(vinylidene fluoride-co-hexafluoropropylene); cellulose butyrate; phosphoryl choline; poly(aspirin); polymers and co-polymers of alkoxymethacrylate, alkoxyacrylate, and 3-trimethylsilylpropyl methacrylate (TMSPMA); poly(styrene-isoprene-styrene)-PEG (SIS-PEG); polystyrene-PEG; polyisobutylene-PEG; polycaprolactone-PEG (PCL-PEG); poly(methyl methacrylate)-PEG (PMMA-PEG); polydimethylsiloxane-co-PEG (PDMS-PEG); polypropylene oxide-co-polyethylene glycol; poly(tetramethylene glycol); hydroxy functional poly(vinyl pyrrolidone); and combinations thereof.
