Abstract

In at least one embodiment, a prosthetic valve assembly comprises a pouch connecting two valves to one another. The valve assembly is delivered by a catheter system. In some embodiments, the valve assembly includes a valve for replacing a mitral valve and a valve for replacing an aortic valve. The valve assembly may optionally include an adhesive layer on the outer surface.

Claims

1. A valve assembly comprising:

a first valve;

a second valve;

a pouch connecting the first and second valve.

2. The valve assembly of claim 1, the first valve comprising a first leaflet and a second leaflet;

and

the second valve comprising a first leaflet, a second leaflet, and a third leaflet.

3. The valve assembly of claim 1, further comprising a layer of adhesive on an outer surface of the prosthetic valve.

4. The valve assembly of claim 1, the pouch comprising:

a main compartment;

a first tubular section extending from the main compartment, the first tubular section attached to the outer surface of the first valve; and

a second tubular section extending from the main compartment, the second tubular section attached to the outer surface of the second valve.

5. The valve assembly of claim 4, the main compartment having a maximum size and volume equal to a size and volume of a heart ventricle.

6. The valve assembly of claim 1, wherein the first valve is configured to replace a native mitral valve and the second valve is configured to replace a native aortic valve.

7. The valve assembly of claim 1, wherein the first valve is configured to regulate flow of blood into the pouch, and the second valve is configured to regulate flow of blood out of the pouch.

8. The valve assembly of claim 4, the main compartment being tubular.

9. A delivery system comprising:

a catheter comprising a sheath defining a lumen and a shaft positioned inside the lumen of the sheath;

a valve assembly, the valve assembly positioned around the shaft and inside the sheath, the valve assembly comprising a first valve, a second valve, and a pouch connecting the first and second valves.

10. The delivery system of claim 9, the shaft of the catheter having a first section with a first diameter, a second section with a second diameter, and a third section with a third diameter where the second diameter is less than the first diameter rand the second diameter is less than the third diameter;

wherein the first valve is positioned around the first section, the pouch is positioned around the second section, and the second valve is positioned around the third section.

11. The delivery system of claim 9, wherein the pouch has a plurality of folds.

12. The delivery system of claim 11, wherein the plurality of folds are circumferential folds.

13. The delivery system of claim 11, wherein the plurality of folds are longitudinal folds.

14. The delivery system of claim 9, wherein the first valve comprises a first leaflet and a second leaflet;

and

the second valve comprises a first leaflet, a second leaflet, and a third leaflet.

15. The delivery system of claim 9, the valve assembly further comprising a layer of adhesive on an outer surface of the valve assembly.

16. The delivery system of claim 9, wherein the first valve is configured to replace a native mitral valve and the second valve is configured to replace a native aortic valve.

17. The delivery system of claim 9, wherein the first valve is configured to regulate flow of blood into the pouch, and the second valve is configured to regulate flow of blood out of the pouch.

18. The delivery system of claim 9, the pouch being tubular.

19. The delivery system of claim 9, the pouch further comprising:

a main compartment;

a first tubular section extending from the main compartment, the first tubular section attached to the outer surface of the first valve; and

a second tubular section extending from the main compartment, the second tubular section attached to the outer surface of the second valve.

20. The delivery system of claim 20, the main compartment having a maximum size and volume equal to a size and volume of a heart ventricle.
