1. A valve prosthesis for implantation within a vascular vessel, comprising:
- a support frame formed from a cannula, the support frame having a proximal end, a distal end, a lengthwise axis, and a transverse axis and comprising a leaflet support portion, a circumferential centering support element disposed adjacent the leaflet support portion on the lengthwise axis and mirroring the leaflet support portion with respect to the transverse axis, and first and second struts disposed between and connecting the leaflet support portion and the centering support element; and
a covering attached to the leaflet support portion and defining 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 opening defined between the proximal end and the distal end of the support frame and extending along the transverse axis between the first and second struts, the covering extending from the opening to the distal end of the support frame and wrapped around the distal end of the support frame such that the covering can engage a wall of said vascular vessel.

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.
