1. A method of manufacturing an implantable medical device, comprising:

  • purifying a polymer by;

    contacting the polymer with a fluid capable of swelling the polymer, wherein the fluid is selected from the group consisting of isopropyl acetate and propyl acetate;

    removing all or substantially all of the fluid from the polymer such that an impurity from the polymer is completely or at least partially removed by the fluid; and

    ;

    coating an implantable medical device with the purified polymer, or fabricating the implantable medical device from the purified polymer;

    wherein the polymer comprises poly(vinylidene fluoride-co-hexafluoropropylene).
