摘要：
A stent graft for deployment in a curved lumen such as the aortic or thoracicarchcomprises a constraining mechanism at its proximal end. A stent provided atthe proximalend of the stent graft includes loops of material that co-operate withrestraining wires thatextend between a central guide wire carrier and a restraining wire cannula.The constrainingmechanism acts to maintain the proximal stent constrained at three pointsaround itscircumference at both the proximal and distal ends of the proximal stent. Theproximal stentis thus allowed to expand after expansion of the remainder of the stent graftduringdeployment. In an embodiment, the constraining mechanism acts to constrain twoadjacentstruts of the proximal stent at three points radially therearound, at theproximal end of thestent and at the distal end of the stent. The proximal stent may then overlapwith the interiorof an adjacent stent at an inner part of a curved vessel.
