Abstract

A valve prosthesis, such as an artificial venous valve, is described. The valve prosthesis has a support frame formed from a cannula and an attached covering that defines an opening adapted to move between a first position in which the opening is open to fluid flow and a second position in which the opening is closed to fluid flow. The support frame includes a leaflet support portion and a circumferential centering support element disposed adjacent the leaflet support portion with respect to a lengthwise axis of the support frame and mirroring the leaflet support portion with respect to a transverse axis of the support frame.
