A vascular patch for closing an incision in a blood vessel includes a base layer of expanded polytetrafluoroethylene (PTFE) having an outer coating of an elastomeric, biocompatible material such as polyurethane to minimize suture hole bleeding. Suture guidelines are formed upon the ablumenal side of the PFTE base layer prior to application of the elastomeric coating to facilitate proper and consistent placement of sutures. A colorant is added to the elastomeric coating to identify the ablumenal side of the vascular patch. The vascular patch is made by mounting an expanded PTFE tube upon a mandrel and applying a water based PFTE ink as a helical stripe about the outer surface of the PTFE tube to form the suture guidelines. The striped PTFE tube is then dip-coated or spray-coated with the elastomeric coating to which the colorant has been added. The PTFE tube is slit to form a flat sheet from which vascular patches are cut.
