    摘要: The present invention is an intralumenal stent device made up of two or more elements. Each element has undulations forming peaks and valleys and is formed from a repeating series including a long segment, a first midsized segment, a short segment, and a second midsized segment. These elements are aligned on a common axis and are connected directly to an adjacent element by a connection. The stent incorporates the advantages of having both long and short segments into a single element.

    摘要: A system for replacing a pulmonary valve includes a conduit having a lumen, a delivery catheter and a replacement valve device disposed on the delivery catheter. The replacement valve device includes a prosthetic valve connected to a valve support region of an expandable support structure. The valve support region includes a plurality of protective struts disposed between a first stent region and a second stent region. A method for replacing a pulmonary valve includes implanting a conduit and delivering a replacement valve device to the conduit. The replacement valve device includes a valve connected to a valve support region that includes a plurality of protective struts. The method also includes deploying the prosthetic valve device from a delivery catheter into the lumen, positioning the prosthetic valve device within the conduit lumen and expanding the prosthetic valve device into contact with the inner wall of the conduit.
