Patent ID: 8871236

Claim:
A method for fabricating an implantable medical article comprising depositing a polymeric blend on at least a portion of the implantable medical device to form a coating, wherein the polymeric blend comprises: (a) a biologically compatible structural component comprising a linear acrylic homopolymer or a linear acrylic copolymer, and (b) a biobeneficial component comprising a copolymer having an acrylate moiety and a biobeneficial moiety, wherein the copolymer composing the biobeneficial component has the formula: wherein (c) m 1 , n 1 , p 1 , r 1 , m 2 , n 2 , p 2 and r 2 are all integers; (d) m 1 ≧0, n 1 >0, p 1 ≧0, r 1 >0; m 2 ≧0, n 2 >0, p 2 ≧0, r 2 >0; and (e) (i) if m 1 =0, then p 1 >0; (ii) if p 1 =0, then m 1 >0; and (iii) if m 2 =0, then p 2 >0; and (iv) if p 2 =0, then m 2 >0; and (v) r 1 and r 2 are the same or different; (vi) m 1 and m 2 are the same or different; (vii) n 1 and n 2 are the same or different; and (viii) p 1 and p 2 are the same or different; (f) X is hydrogen or methyl group; (g) each of R, R 1 and R 2 , independently, is methyl, ethyl, n-propyl, iso-propyl, n-butyl, sec-butyl, iso-butyl, tert-butyl, lauryl, or 2-hydroxyethyl; and (h) Q is a fragment providing the copolymer with biobeneficial properties.
