Abstract
Valve prostheses are disclosed that are adapted for secure and aligned placement relative to a heart annulus. The valve prostheses may be placed in a non-invasive manner, e.g., via trans-catheter techniques. The valve prosthesis may include a support ring, a plurality of leaflet membranes mounted with respect to the support ring, and a plurality of retention clip elements. The support structure is advantageously formed from a tubular member or flat stock of shape memory metal. A delivery system for delivery of a valve prosthesis embodying the disclosed support structure is also disclosed.
