Cross-linked polyethylene oxide coatings to improve the biocompatibility of implantable medical devices

摘要

Polyethylene oxide (PEO) coatings providing improved biocompatibility for implantable medical devices are disclosed. The PEO coatings comprise functionalized end-capped PEO which is attached at one end to the medical device. The PEO compounds are then exposed to a high energy source for a time sufficient to cause the PEO compounds to form a cross-linked, insoluble network. These PEO coatings are able to survive ethylene oxide sterilization procedures with minimal loss of protein or cell repulsion ability.
