Patent ID: 8158187

Claim:
A method of making a dry diazeniumdiolated polymer coated medical device comprising the steps of: a) providing a medical device; b) coating said medical device with a secondary amine functionalized polymer; wherein said secondary amine functionalized polymer is a polymer represented by Formula I: wherein R 1 is selected from the group consisting of C 1 -C 18 alkyl, 2-hydroxyethyl, 2-ethoxyethyl, glycidyl, and poly(ethylene glycol); R 2 is C 1 -C 18 alkyl or C 1 -C 18 multiple amine; and wherein a and b are each independently an integer between 1 and 25,000; c) drying said secondary amine functionalized polymer coated medical device; and d) exposing said dried secondary amine functionalized polymer coated medical device to nitric oxide gas under pressure; to form the dry diazeniumdiolated polymer coated medical device.
