The present invention provides a process for enhancing biomaterial biocompatibility. A biocompatibility-enhancing coating is covalently attached to a biomaterial surface through spacer arm-providing molecules previously covalently bonded to the functionalized surface. Also provided are biomaterials of...http://www.google.com.au/patents/US5217743?utm_source=gb-gplus-sharePatent US5217743 - Biomaterials of enhanced biocompatibility
