Collapsible atrioventricular valve prosthesis

1. A collapsible atrioventricular valve, comprising:

an annulus frame, wherein the annulus frame includes three prongs extending therefrom, with at least one catch positioned on the annulus frame between each of the three prongs, and wherein each prong is comprised of two wire-form structures constrained together by a hypo tube wrapped and permanently affixed around the two wire-form structures;

at least two leaflets attached with the annulus frame and prongs to form a valve; and

wherein the annulus frame is a saddle-shaped annulus having a crest reflecting curvature of the saddle-shaped annulus.

2. The collapsible atrioventricular valve as set forth in in claim 1 , where the annulus frame further comprises at least one catch that acts to hold the annulus frame secure on an atrioventricular junction or at an atrial or ventricular side of a heart, the catch projecting from the annulus frame directly beneath the crest, whereby when implanted the collapsible atrioventricular valve lies between a heart's atrium and ventricle.

3. The collapsible atrioventricular valve as set forth in in claim 2 , wherein the prongs project from the annulus frame in a first direction and the at least one catch projects from the annulus frame in a direction away from the first direction.

4. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annulus frame is symmetric.

5. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annulus frame is axisymmetric.

6. The collapsible atrioventricular valve as set forth in in claim 1 , where the annulus frame is asymmetric.

7. The collapsible atrioventricular valve as set forth in claim 1 , wherein the hypo tube has at least one hole that can be used for attachment to a delivery system.

8. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the valve is collapsible with a delivery system for percutaneous heart valve delivery.

9. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annular frame is made of a monolithic wire.

10. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annular frame is formed of a plurality of frame subcomponents.

11. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annular frame is formed of shape-memory material selected from a group consisting of Nitinol, Cobalt-Chromium and polymers.

12. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the valve is configurable between a collapsed configuration and an open configuration, such the collapsed configuration allows the valve to be delivered into position against a native atrioventricular valve annulus and upon expanding to the open configuration, the atrioventricular valve is secured in place by the at least one catch.

13. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the leaflets are formed of a material selected from a group consisting of pericardial tissue, polymeric material, and leaflet tissue material.

14. The collapsible atrioventricular valve as set forth in in claim 1 , wherein a surface of the annular frame is rough, thereby accommodating improved sitting at an atrioventricular junction.

15. The collapsible atrioventricular valve as set forth in in claim 14 , wherein the annular frame is a wire frame and the surface of the annular frame is rough due to external components added to the wire frame.

16. The collapsible atrioventricular valve as set forth in in claim 14 , wherein the annular frame is a wire frame and the surface of the annular frame is rough due to an inherent roughness of the wire frame.

17. The collapsible atrioventricular valve as set forth in in claim 1 , further comprising a periphery skirt attached to a circumference of the annular frame, whereby the periphery skirt serves to minimize paravalvular leakage once implanted in a patient.

18. The collapsible atrioventricular valve as set forth in in claim 17 , wherein the periphery skirt is formed of a material selected from a group consisting of pericardial tissue, polymeric material, and leaflet tissue material.

19. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the valve is collapsible and is deliverable to heart chambers via transapical approach.

20. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the valve is collapsible and is deliverable to heart chambers through peripheral vasculature, comprising transfemoral artery/vein, aorta/vena cava, subclavian vasculature or jugular veins.

21. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the valve is collapsible and is deliverable to heart chambers via surgical procedures comprising, thoracotomy, mini-thoracotomy and minimally invasive heart surgery.

22. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annulus frame includes five catches, such that one catch is positioned on the annulus frame between a first set of adjacent prongs, and two catches are positioned on the annulus frame between a second set of adjacent prongs, and two catches are positioned on the annulus frame between a third set of adjacent prongs.

23. The collapsible atrioventricular valve as set forth in in claim 1 , wherein the annulus frame includes four catches, such that one catch is positioned on the annulus frame between a first set of adjacent prongs, and one catch is positioned on the annulus frame between a second set of adjacent prongs, and two catches are positioned on the annulus frame between a third set of adjacent prongs.
