Abstract
Abstract The present invention relates to a medical device, and in particular, to a stent-based valve. The valve includes a radially expandable structural frame comprising a proximal and distal anchors formed from a lattice of interconnected elements, and having a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between. One or more cantilevered valve struts are attached directly or indirectly to the proximal anchor. The stent based valve also comprises one or more connecting members attached between the proximal and distal anchors. A biocompatible valve assembly is coaxially disposed and attached to the proximal anchor and extends in the longitudinal direction along the one or more connecting members.
