Abstract
An endovascular stent-graft is provided, including a plurality of circumferential strut members disposed at respective axial positions along a self-curving longitudinal portion thereof. Each of the circumferential strut members is shaped so as to define a plurality of proximal peaks. When the stent-graft is unconstrained in a radially-expanded state, for at least one of the circumferential strut members, a first set of the proximal peaks of the circumferential strut member, which includes at least a circumferentially-closest one of the proximal peaks to an outermost curve of the self-curving longitudinal portion, are bent radially inward at least an average angle of 20 degrees toward a central longitudinal axis of the self-curving longitudinal portion, and a second set of the proximal peaks of the circumferential strut member are not bent radially inward by at least an average angle of 20 degrees toward the central longitudinal axis. Other embodiments are also described.
