Patent number: 11813185Abstract: An endovascular system includes an elongate delivery shaft assembly, which, when a stent-graft is removably constrained in a radially-compressed delivery state along a distal end portion of the delivery shaft assembly, is shaped so as to define a self-orienting portion, which is shaped so as to define (a) at least proximal and distal curved portions, the proximal curved portion disposed more proximal than the distal curved portion, and (b) at least one point of inflection on a central longitudinal axis of the delivery shaft assembly longitudinally between the proximal and the distal curved portions. Upon positioning of a distal tip of the system near a bifurcation of a brachiocephalic artery from an aortic arch, the self-orienting portion automatically rotationally orients itself in the aortic arch to a rotational orientation in which an inferior lateral opening of the stent-graft faces upstream in the aortic arch. Other embodiments are also described.Type: GrantFiled: June 15, 2022Date of Patent: November 14, 2023Assignee: ENDOSPAN LTD.Inventors: Yaniv Marmur, Or Zigelboim, Alon Shalev

Patent number: 11389313Abstract: A method for treating a subject includes providing an endovascular system that includes a stent-graft and an elongate delivery shaft assembly. When the delivery shaft assembly is unconstrained and the stent-graft is removably constrained along a distal end portion of the delivery shaft assembly, the delivery shaft assembly is shaped so as to define a self-orienting portion, which is shaped so as to define at least proximal and distal curved portions. The delivery shaft assembly is transvascularly introduced into a descending aorta of the subject and a distal end of the delivery shaft assembly is advanced to an aortic arch, such that the self-orienting portion assumes a desired rotational orientation in the aortic arch. While the distal end of the delivery shaft assembly is positioned in the aortic arch, the stent-graft is released from the distal end portion of the delivery shaft assembly. Other embodiments are also described.Type: GrantFiled: June 23, 2020Date of Patent: July 19, 2022Assignee: ENDOSPAN LTD.Inventors: Yaniv Marmur, Or Zigelboim, Alon Shalev
