A heart valve system, the system including a radially self-expandable tubular body, a valve, and a tubular fabric. The tubular body having an inflow end and an outflow end and including a plurality of struts with at least one motion buffer component integrated in the tubular body. The valve being coupled to the tubular body and including a plurality of valve leaflets. The fabric being disposed over an outer surface of the tubular body and over an outer surface of the motion buffer component. Additionally, when the outflow end of the tubular body moves radially inward from movement of the valve leaflets, the motion buffer component being configured so as to not move radially inward with the outflow end of the tubular body.
