Patent ID: 8529931

Claim:
An implantable device comprising a polymer blend comprising a random biocompatible polymer and at least one other biocompatible polymer, wherein the random biocompatible polymer comprises fluorinated monomers and hydrocarbon monomers, wherein the hydrocarbon monomers are CHR=CH 2 in which R is selected from the group consisting of phenyl, substituted phenyl, cyclic alkyl, heterocyclic alkyl, and heteroaryl, or CR′ 2 =CH 2 in which R′ is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, short chain alkyl groups, phenyl, substituted phenyl, cyclic alkyl, heterocyclic alkyl, and heteroaryl, wherein the fluorinated monomers are selected from the group consisting of —CF 2 —CF 2 —, —CH 2 —CF 2 —, —CH 2 —CHF—, —CHF—CHF—, —CClF—CF 2 —, —CF 2 —C(CF 3 )F—, —CHF—C(CF 3 )F—, —CF 2 —C(CF 3 )H—, —CF 2 —CR″F—, —CHF—CR″F—, —CF 2 -CR″H—, —CH 2 —CR″F— and —CFH—CR″H—, where R″ is independently selected from hydrogen, Cl, Br, I, methyl, ethyl, n-propyl, iosopropyl, short chain alkyl groups, phenyl, substituted phenyl, cyclic alkyl, heterocyclic, heteroaryl, fluorinated short chain alkyl groups, fluorinated phenyl, fluorinated cyclic alkyl, fluorinated heterocyclic, and combinations thereof, wherein the fluorinated monomers form about 25.01 mole % to about 99.99 mole % repeating units of the polymer, and wherein the hydrocarbon monomers form about 74.99 mole % to about 0.01 mole % repeating units of the polymer.
