Aortic arch endovascular stent-graft

An aortic arch endovascular stent-graft is a tubular device designed to treat aneurysms or dissections in the aortic arch and descending thoracic aorta. Placed inside the blood vessel via a catheter, it expands to reinforce the weakened artery wall, restoring proper blood flow while excluding the damaged section.

These devices are typically regulated as high-risk medical technology, often requiring pre-market approval or conformity assessment before commercialization. They are generally supplied as single-use, sterile implants, with associated disposable tools for deployment, and are classified differently depending on the jurisdiction and specific design features.
