Packaging for Medical Devices Coated with Perfluorinated Liquids or Dispersions Thereof
The present disclosure includes and provides for methods of packaging medical devices that are to be treated with a fluorinated liquid to alter their surface properties, packaging systems for such medical devices, and methods of utilizing the packaging systems to treat the medical devices. The packaging systems permit effective storage and distribution of medical devices that upon contact with mammalian blood have limited thrombogenicity or are non-thrombogenic and/or are resistant to adhesion of blood cells or clots.
