Valve component, frame component and prosthetic valve device including the same for implantation in a body lumen
Described herein 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.
1. A method for treating, preventing or ameliorating a symptom associated with a disease, disorder, or condition caused by a dysfunctional mammalian valve, comprising:
providing a prosthetic valve device 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; and
delivering said prosthetic valve device to an implantation site in a mammalian subject in need thereof.
2. The method according to claim 1 , wherein the annular sleeve and the annular belt comprise a biological tissue.
3. The method according to claim 1 , wherein the prosthetic valve device is configured for transluminal delivery.
4. The method according to claim 1 , wherein the disease, disorder, or condition is caused by a dysfunctional valve selected from: an aortic valve, a mitral valve; and a pulmonary cardiac valve.
5. The method according to claim 4 , wherein the dysfunctional valve is an aortic valve.
6. The method according to claim 1 , wherein the disease, disorder, or condition is selected from: aortic stenosis; valve regurgitation; and calcification of the leaflets.
7. The method according to claim 1 , wherein the leaflets are free of affixing penetrations.
8. The method according to claim 1 , wherein the leaflets are free of anchoring penetrations.
9. The method according to claim 1 , wherein the implantation site is a degenerated valve.
10. The method according to claim 1 , wherein a compression fit between the prosthetic valve device and the body lumen is created at the implantation site.
11. The method according to claim 10 , wherein the frame comprises a shape memory metal.
