A stent graft system including a component having longitudinally extending outer surface and inner surface, the inner surface defining a lumen having a longitudinal axis, a plurality of stents distributed longitudinally along the component, and a plurality of suture loops, each suture loop attached to the inner outer surface, of the stent graft, a first suture loop spaced laterally and longitudinally relative to an adjacent suture loop when the component is in an expanded configuration, the plurality of suture loops aligned longitudinally along the stent graft when the stent graft is in a radially constricted configuration, at least one ligature having a proximal end and a distal end, the ligature extending through at least some of the plurality of suture loops, whereby tension on the at least one ligature longitudinally aligns the suture loops along the longitudinal axis of the component, thereby at least partially radially constricting the stent graft.

A stent graft delivery system and method for implanting a stent graft includes and employs at least one control rod that extends along a luminal wall of a stent graft and at least one ligature. The ligature extends about radial stents. Rotation of the control rod or a tube extending about the control rod wraps the ligature about the control rod, thereby radial constricting the stent about which the ligature extends.

Systems and methods for reloading a stent graft delivery device are disclosed. Additionally, a kit including a patient-specific fenestration template, fenestration rings and sutures can be provided for forming fenestrations in a preexisting, or generic, stent graft with the fenestrated stent graft then reloaded within the sheath of the delivery device for deployment within a patient.

A medical device including a expandable graft and valve attachment and methods related to attaching the valve (with or without an elongated graft portion) to a fenestrated stent graft are disclosed. The device and methods disclosed herein are particularly suitable for Endo-Bentall procedures via a minimally invasive endovascular technique used to repair the aortic root and ascending aorta. An exemplary device has a larger diameter at a proximal end with fenestrations associated with tunnel lumens longitudinally aligned with the graft lumen. The proximal end of the main graft lumen receives a valve, wherein the graft lumen trifurcates in a retrograde manner parallel with the first tunnel and second tunnel. The first and second tunnel is configured to receive a first and second bridging stent.

A delivery device prevents longitudinal expansion of an aortic prosthesis under compression by engagement of a clutch with a pin upon release of a handle rotating a gearing mechanism about the pin that advances the aortic prosthesis during endovascular implantation at a surgical site.

Devices, systems, and methods for marking and/or reinforcing fenestrations in grafts are disclosed herein. In some embodiments, a radiopaque marker for a graft is provided. The marker can be secured to the graft in the area near a fenestration such that the marker is visible via radiographic imaging. The radiopaque marker can be in the form of a radiopaque thread, a radiopaque bead, a radiopaque additive, or a radiopaque adhesive. In some embodiments, the radiopaque marker is in the form of a circular disc shaped and sized to surround a fenestration, the circular disc being formed of a radiopaque material. The radiopaque marker can be configured to or can be attached to a reinforcement member configured to reinforce a fenestration such that one or more edges of the fenestration are protected and/or to aid in engagement with and sealing to a mating stent.
