1. A radially expandable artificial valve prosthesis for regulating fluid flow through a body vessel, comprising:
- a ring frame, wherein the ring frame is radially expandable to form an expanded ring frame having an expanded ring frame width;
a first valve leaflet, wherein a first portion of a perimeter of the valve leaflet is attached to the ring frame to form a valve pocket having a valve pocket height of less than the expanded ring frame width, and a support structure attached to the ring frame, wherein the support structure positions the ring frame within the bodily vessel, wherein the first valve leaflet allows fluid flow in a first, antegrade, direction and restricts flow in a second, retrograde direction.
