Abstract:
A method of treating the surface of a medical device with a biomolecule comprising the steps of: providing a polyolefin substrate forming a medical device; cleaning the polyolefin substrate; exposing the polyolefin substrate to a reactive gas containing acrylic acid and to plasma energy to yield a plasma-deposited polyacrylic acid coating on the polyolefin substrate; and attaching a biomolecule, such as heparin, to the polyolefin substrate following formation of the plasma-deposited polyacrylic acid coating on the polyolefin substrate.
