Abstract

A stent graft apparatus for endovascular treatment of aortic diseases includes a balloon-expandable section and a self-expanding section connected by radial sutures to form a unitary device. The balloon-expandable section comprises a metallic framework configured for deployment via balloon inflation and includes a plurality of radially equidistant radiopaque markers for fluoroscopic visualization. The self-expanding section comprises a shape-memory material configured to exert continuous radial force upon release. The connected sections are sequentially deployed through a catheter-based delivery system, allowing the balloon-expandable section to anchor the graft precisely at the treatment site before the self-expanding section is released to conform to the vessel anatomy. This configuration facilitates both accurate positioning and anatomical adaptability, reducing the risk of migration and improving fixation in complex aortic regions. The apparatus may be used to treat aneurysms, dissections, or injuries in various segments of the aorta.
