Abstract
Disclosed is a method for producing a hemocompatible article. A non-thermally stabilized polytetrafluoroethylene membrane comprised of non-oriented fibers is heated to a temperature of around 400° C. and above the gel point of the polytetrafluoroethylene, while the membrane is being applied against a forming mold. The membrane is applied against the forming mold by generating a pressure differential between opposing faces of the membrane to form a conformed membrane. The conformed membrane is then cooled, thereby producing the hemocompatible article.
