Artivion has been granted a patent for an intraluminal vessel prosthesis system designed for implantation in the aortic arch region. The system includes a main vessel prosthesis and an anchoring vessel prosthesis, with the diameter of the anchoring vessel prosthesis being at least 45% smaller than the main vessel prosthesis. The length of the anchoring vessel prosthesis is also shorter than the main vessel prosthesis. The system aims to provide effective treatment for patients with aortic arch conditions.

Intraluminal vessel prosthesis system for aortic arch implantation
A recently granted patent (Publication Number: US11684497B2) describes an intraluminal vascular prosthesis system designed for implantation in the aortic arch of a patient. The system includes a main vessel prosthesis and at least one anchoring vessel prosthesis. The main vessel prosthesis is a hollow-cylindrical structure with a lumen, a stent frame, and a prosthesis material secured to it. The anchoring vessel prosthesis is securely attached within the lumen of the main vessel prosthesis, with a smaller diameter and shorter length. The first lumen ends of both the main vessel prosthesis and the anchoring vessel prosthesis are flush with each other.
The system also includes a side vessel prosthesis, which can be inserted into the lumen of the anchoring vessel prosthesis via the first lumen end. The side vessel prosthesis has a decreasing diameter from its first lumen end to its second lumen end. The main vessel prosthesis may have a jacket surface with a fenestration, allowing the insertion of the side vessel prosthesis into the lumen of the main vessel prosthesis and partially into the lumen of the anchoring vessel prosthesis.
The stent frames of the main vessel prosthesis, anchoring vessel prosthesis, and side vessel prosthesis can be chosen from various options, including laser-cut stent frames, individual stent springs, or braided stent frames. The stent frames may have non-interconnected stent rings arranged in a meandering formation, with a prosthesis material fixedly connected to the stent rings. The meandering circumferential course of at least one stent ring may have a non-uniform amplitude.
The diameter of the main vessel prosthesis can range from 24 mm to 42 mm, while the diameter of the anchoring vessel prosthesis can range from 6 mm to 14 mm. The diameter of the side vessel prosthesis can range from 6 mm to 16 mm. The anchoring vessel prosthesis can be mounted on the inner wall of the main vessel prosthesis using sewing, adhesive bonding, or welding.
The patent also describes methods for implanting the intraluminal vascular prosthesis system into the aortic arch and treating vascular diseases in the aortic arch using the system. These methods involve inserting and releasing the main vessel prosthesis and the side vessel prosthesis in the appropriate regions.
Overall, this patent presents a novel intraluminal vascular prosthesis system and methods for its implantation and treatment of vascular diseases in the aortic arch. The system's unique design and configuration aim to provide effective treatment options for patients with aortic arch conditions.
