Compositions and methods for promoting patency of vascular grafts
First Claim
1. A method for increasing the patency of a vascular graft comprising a biodegradable polymer, the method comprisingincorporating into or onto the graft monocyte chemoattractant protein 1 (MCP-1), wherein the MCP-1 is locally released from the graft in an effective amount following graft implantation to recruit an effective amount of host monocytes to the graft within one week of graft implantation to prevent, inhibit or reduce stenosis, and promote neotissue formation and increase the patency of the graft in the host over time relative to the patency of the graft in the absence of MCP-1.

Abstract
Methods for increasing the patency of biodegradable, synthetic vascular grafts are provided. The methods include administering one or more cytokines and/or chemokines that promote outward tissue remodeling of the vascular grafts and vascular neotissue formation. The disclosed methods do not require cell seeding of the vascular grafts, thus avoiding many problems associated with cell seeding. Biodegradable, polymeric vascular grafts which provide controlled release of cytokines and/or chemokines at the site of vascular graft implantation are also provided.
