Abstract
A device configured for implantation at a heart valve comprises an expandable stent. The stent comprises a first stent segment extending along a first length portion of the stent. The first stent segment is configured to be positioned and radially expanded against a vascular wall of a native aortic valve site. The first stent segment comprises a plurality of closed cell structures defining a circumference of the stent along the first length portion. The plurality of closed cell structures has a uniform density around the circumference. The stent also comprises a second stent segment disposed along a second length portion of the stent. The second stent segment comprises a plurality of interconnected strut members disposed around a circumference of the stent in alternating regions having a first strut density and a second strut density. The first strut density is higher than the second strut density.
