Abstract
Abstract An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system. Furthermore, the graft may be configured with a plurality of synthetic fiber tufts secured to the outer surface of the tubular body to facilitate sealing the graft within the vessel. The graft may also include a plurality of crimps formed in the tubular body of the graft.
