Abstract
The present examples provide a stent for use in a medical procedure that comprises at least one apex having first and second generally straight portions and a curved portion disposed between the first and second straight portions. The curved portion may comprise at least one region having a cross-sectional area that is less than a cross-sectional area of the first and second straight portions, which may facilitate compression of the stent and insertion of the stent into smaller vessels. The stent may be used alone, or in conjunction with a stent-graft, and may comprise one or more barbs configured to engage an inner wall of a vessel or duct.
