Abstract
The disclosure relates to a tapered stent and flexible prosthesis. The stent has a first longitudinal region and a second longitudinal region. The second region is substantially parallel to and spaced axially apart from the first region. A plurality of struts is disposed intermediate the first region and the second region and circumferentially connects the first region and the second region. The first region has a longitudinal length that is greater than the second region longitudinal length. The struts have varying longitudinal lengths that gradually decrease from the first region to the second region. The flexible prosthesis comprises at least two alternating tapered stents.
