Abstract
Abstract A stent includes a stent member having a plurality of post members formed therein. Each post member is connected to an adjacent post member by an interconnecting portion. A plurality of leg members extend from the stent member. The stent may be molded within a flexible polymer valve. The legs stabilize and locate the stent in the mold. Upon completion of the molding process, the legs can be separated from the stent.
