INTRALUMINAL GRAFTING SYSTEM

摘要

An intraluminal grafting system (121) comprises a generally sinusoidal wire frame (131) having apices (136) which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices (136) and the base apices (132) are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members (161) that are oriented in a responsive relationship to the radially outward bias of the attachment system. The graft may include a plurality of synthetic fiber tufts (318) 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 (374) formed in the tubular body of the graft.
