Abstract
A heart valve includes a stent for fixing the heart valve in a bodily vessel and a stentless valve portion for restricting the flow of blood through the valve to a single direction. The valve portion is supported and suspended in the bodily vessel via connectors spanning a gap between the valve portion and the stent or by a direct end-to-end connection with the anchor portion.
