Abstract
A prosthetic valve device, including a valve component, frame and methods of manufacturing the same. The present invention, in some embodiments, is a prosthetic valve device having an optimized valve component for durability and functionality of the collapsible leaflets. Specially designed commissures contribute to the optimization along with identified parameters. In other embodiments, the invention, is a frame formed from a unique cutting pattern.
Claims19
A prosthetic valve device for implantation into a body lumen comprising:
- a frame comprising a tubular body;
- and
- a valve component disposed within and anchored to the tubular body of the frame, the valve component comprising:
- an annular sleeve having an annular inner wall that forms a fluid passageway along an axis from an inlet edge to an outlet edge, the annular sleeve folded over at the inlet edge to form an annular cuff that is concentric to and surrounds the annular inner wall and extends from the inlet edge toward the outlet edge;
- and
- an annular belt positioned between the annular inner wall and the annular cuff and having a bottom edge adjacent to a bight portion of the annular sleeve that forms the inlet edge;
- wherein the annular sleeve and the annular belt are formed of a material selected from the group consisting of a biological tissue and a biocompatible polymer.
