Frame based unidirectional flow prosthetic implant
First Claim
1. A prosthetic valve comprising:
- a radially expandable structural frame having a substantially cylindrical configuration with a first and a second open end and a longitudinal axis defining a longitudinal direction extending there between, the structural frame including a proximal anchor, a distal anchor, one or more connecting members connected between the proximal anchor and distal anchor, and one or more cantilever valve struts having first and second ends, the first end of the cantilever valve strut being attached to the proximal anchor; and
a tubular membrane coaxially disposed over the structural frame assembly, the tubular membrane being attached to the proximal anchor and extending distally along the one or more connecting members.

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.
