Stents, Vascular, Aorta, Balloon Expandable
Definition : Aorta vascular stents designed to be expanded by the application of a constant radial pressure to the artery walls using a low-pressure balloon after delivery through an appropriate stent delivery system. These endoprostheses are usually metallic (e.g., stainless steel) stents; they are available in a variety of lengths (e.g., from 4 to 25 cm/1.5 to 10 inches) with maximum diameter after expansion about 50 mm (2 inches). Balloon-expandable aorta stents are intended to form a scaffold that holds and reinforces the aorta open to prevent restenosis; they are usually mounted on balloon delivery catheters. Stents intended to treat aorta (type A) dissections (that may be combined with placement of aorta prostheses during open surgery) and for lower aorta dissections (usually performed percutaneously through the vasculature) are available.
