OPTIMALLY EXPANDED, COLLAGEN SEALED EPTFE GRAFT WITH IMPROVED TISSUE INGROWTH

摘要

The present invention provides a method of making a temporarily blood-tight implantable ePTFE material for improved tissue ingrowth and delivery of therapeutic agents comprising providing an ePTFE material having an average internodal distance of 60 - 200 microns, preparing a biodegradable hydrogel sealant also comprising a therapeutic agent infusing the ePTFE material with the biodegradable hydrogel sealant, and curing the ePTEE material.
