Abstract
The present invention relates to a medical device, and in particular, to a stent-based valve (100) . The valve includes a radially expandable structural frame (101) comprising a proximal and distal anchors (103 , 104) 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 (1101) are attached directly or indirectly to the proximal anchor (103) . 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.
