Abstract: A stent graft for treating an arterial aneurysm includes a ligature traversing at least a portion of struts of stents, the ligature having ends that, when linked, at least partially constrict a radial dimension of the stents. The ends of the ligature can be linked by a wire in a stent graft delivery system that threads anchor loops longitudinally spanning ends of the ligature to maintain the stent in a radially constricted position during delivery to the aneurysm. The stent graft can be implanted at the aneurysm by retracting the wire from the linked ends of the ligature and from the anchor loops, thereby releasing the associated stent from the radially constricted position.

Abstract: A delivery system and method for implanting a stent graft prostheses includes and employs a torque component at a distal end of the stent graft prosthesis, whereby following advancement of the stent graft to a surgical site in a constrained or partially constrained configuration, torque is applied to the torque component and, consequently, to the stent graft to rotationally align the stent graft about a longitudinal axis of the stent graft, followed by deployment of the stent graft in correct rotational alignment, and subsequent retraction of the delivery device from the deployed stent graft and the subject. The torque component includes a pushrod and at least two arms.
