Abstract
A method for inhibiting or suppressing stenosis associated with an arteriovenous access. A dosage of photosensitive compound is introduced into the artery or vein. An anastomotic area of the artery or vein is then exposed to a source of light having a wavelength suitable for photoactivating the photosensitive compound for a period of time sufficient to provide a therapeutic effect. A method is also described for the delivery of drugs into the anastomotic site of an AV access to inhibit the formation of stenotic lesions at those sites.
