A radially expandable endoprosthesis device and method of deployment with an at least two stage deployment capability. More particularly, the device pertains to an annularly expandable heart valve prosthesis which is adapted for the long-term treatment of valvular diseases in infants, children and adolescents. The device is constituted of a combination of superelastic alloys and bioresorabable materials which facilitates the devices to undergo multistage deployments at predetermined intervals while emplaced in the body vessels or lumens of patients. |
