Patent ID: 8746168

Claim:
A system for grafting a coating polymer onto a surface of a device, the system comprising: a) a photoinitiator station comprising a photoinitiator tank for coating said device with a photoinitiator solution; b) a grafting station comprising: i) a grafting tank, for submerging said device into a polymerizable solution; ii) a diffuser coupled to a gas feed, disposed within said grafting tank for bubbling an oxygen-scavenging gas from said gas feed into said polymerizable solution; and iii) a UV light source, positioned to expose said device to UV light for activating the photoinitiator on said device; wherein said grafting is effected by submerging said device in said polymerizable solution while bubbling said gas therethrough and exposing said device to said UV light source; and c) a rail, for transferring said device from said photoinitiator tank to said grafting tank without first drying said device.
