Abstract
An implantable valve prosthesis for preventing blood reflux from a cardiac atrium into a vein opening into the atrium, with a generally tubular stent (), also a flexible tube () that can be closed by collapsing the tube () and which is arranged at least in a partial area of a second end section () of the stent () on the outer peripheral surface. The second end opening () of the flexible tube () is open in the pressureless state. As a result of this valve design, during a physiological flow out of the pulmonary vein in the direction of the left atrium or out of the caval vein in the direction of the right atrium, there is no rise or an only insubstantial rise in the resistance to flow.
