Reporters obtained the following quote from the background information supplied by the inventors: "The present invention relates generally to implantable expandable medical devices and more particularly to implantable endoluminal stents, covered-stents, stent-grafts and grafts employed to restore and maintain patency of anatomical passageways within a mammalian body. The dramatic success enjoyed by a variety of endoluminal implantable medical devices has largely been the result of their ability to be delivered utilizing minimally invasive techniques that significantly reduce the trauma to the patient. While there are many types of endoluminally-delivered implantable medical devices, the present invention relates specifically to generally tubular devices that are expandable from a first smaller diameter suitable for minimally invasive delivery to a second enlarge diameter suitable for restoring and maintaining patency of the anatomical passageway.
"The most prevalent type of implantable expandable endoluminal device is the stent. Stents are typically used to treat occlusive and anuersymal disease or trauma and are, typically, generally tubular structural scaffolds typically consisting of latticed arrays of circumferential members and longitudinal members. The circumferential members typically permit the stent to radially expand from the first to the second diameter while the longitudinal members provide column strength and longitudinal flexibility. A variant of the stent, termed in the art either a stent-graft or covered stent, consists of a stent or other structural scaffold covered with a graft. Stent-grafts are devices typically employed for exclusionary purposes for purposes of creating a conduit, such as in excluding an abdominal aortic aneurysm, whereas covered stents are devices typically employed in treating occlusive conditions, such as coronary artery disease to restore patency to the coronary artery. Conventional stent-grafts and covered stents employ polymeric covers, such as polyester or expanded polytetrafluoroethylene that are either affixed to the stent by barbs or sutures or are retained on the stent by adhesion either to the stent or to an opposing graft surface.
"Recently, radially expandable metallic grafts have been disclosed in co-pending, commonly assigned U.S. patent application Ser. Nos. 10/135,316 and 10/135,626, both filed
