System and method for coating medical devices

摘要

One aspect of the present disclosure can include a method for grafting a coating polymer onto a surface of a device. The method can include the following steps: a) submerging the device into a photoinitiator solution; b) without first drying the device, submerging the device into a polymerizable solution; c) bubbling an oxygen-scavenging gas through the polymerizable solution; d) applying a UV light to the device to activate the photoinitiator, thereby grafting the coating polymer onto the device; and e) drying the device.

1. A method for grafting a coating polymer onto a surface of a device, the method comprising:
a) submerging said device into a photoinitiator solution in a first tank in the absence of monomer; b) without first drying said device, submerging said device into a polymerizable solution in a second tank; c) bubbling an oxygen-scavenging gas through said polymerizable solution; d) applying a UV light to said device to activate said photoinitiator, thereby grafting said coating polymer onto said surface; and e) drying said device, wherein UV light is applied to the device only when the device is submerged into the second tank.
