Abstract
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.
