Management of a Thoracic Aortic Aneurysm Using a Talent Stent Graft

Abstract

The Talent thoracic stent graft system is composed of a self-expanding serpentineshaped nitinol endoskeleton inlaid in a woven polyester graft. The Talent has a longitudinal support bar throughout the length of the endograft, which provides column strength while maintaining device flexibility to accommodate tortuous vessels. Individual stents are secured to the graft with suture. Between individual stents is an unsupported graft to allow for flexibility. The proximal end of this stent graft is made in two configurations, which include either a serrated (open web configuration) or an open bare stent segment (FreeFlo configuration). The bare stent FreeFlo configuration allows device implantation across the orifice of the left subclavian or common carotid artery while maintaining antegrade blood flow. A similar bare wire configuration is also available in the distal stent graft, which permits the uncovered device to anchor across the celiac artery.
