First Claim
Patent Images
1. A medical article comprising a coating disposed on at least a portion of an implantable medical device, the coating comprising:
- (a) a fluorinated polymer; and
(b) a biologically beneficial polymer;
wherein the fluorinated polymer is selected from the group consisting of;
(i) products of polymerization of fluorinated olefins;
(ii) fluorine-containing cyclic polymers having a main chain with an asymmetrical cyclic structure selected from a group consisting of polymers of repeating units of cyclically polymerized perfluorallyl vinyl ether, perfluorobutenyl vinyl ether, and a combination thereof;
and(iii) copolymers of perfluoro-2,2-dimethyl-1,3-dioxole with perfluoroolefins or with perfluoro(alkyl vinyl)ethers;
wherein the biologically beneficial polymer is selected from the group consisting of poly(ester amide) polymers of a general formula
-[M-P]m-[M-Q]n-, and combinations of these poly(ester amide) polymers,wherein M is a moiety represented by the structure

Abstract
Coatings for an implantable medical device and a method of fabricating the coatings are disclosed. The coatings comprise a fluorinated polymer and a biologically beneficial polymer, an example of which includes poly(ethylene-glycol)-block poly(butylene terephthalate)-block poly(ethylene-glycol). A biologically active agent can be additionally conjugated to the biologically beneficial polymer.
