USES FOR MEDICAL DEVICES HAVING A LUBRICIOUS, NITRIC OXIDE-RELEASING COATING FOR THE THERAPY OF VASCULAR DISORDERS

摘要

Methods are provided for delivering nitric oxide to the vascular tissue of a patient to inhibit or prevent restenosis or improve vascular function following various surgical procedures or associated with various NO-related conditions. The disclosed methods comprise contacting the vascular tissue of a patient with a medicaldevice coated with a coating comprising nitric oxide associated with and releaseable from a polyurea network formed from the reaction on said medical device of a polyisocyanate; an amine donor and/or hydroxyl donor; an isocyanatosilane adduct having terminal isocyanate groups and at least one hydrolyzable alkoxy group bonded to silicon; and optionally a polymer selected from the group consisting of polyethylene oxide, polyvinyl pyrrolidine, polyvinyl alcohol, polyethylene glycol, and polyacrylic acid.
