Abstract

A valve holder assembly having a main valve holder and a detachable secondary valve holder for positioning a heart valve prosthesis.

Claims

1. A valve holder assembly comprising:

a rigid, hollow, generally cylindrical and open main valve holder having a top member adapted to receive a main valve holder handle, a generally cylindrical main valve holder ring base, and support members connecting the main valve holder top member and the ring base, the main valve holder adapted to hold a prosthetic valve; and

a removable secondary valve holder nested within the hollow space of the generally cylindrical main valve holder and having substantially the same centerline as the main valve holder, said secondary valve holder comprising;

a flat, disc-shaped secondary valve holder top member removably connected to the main valve holder top member;

a rotational axle coupled to said secondary valve holder top member;

three elongated commissural posts extending radially from said top member and rotational axle along a substantially horizontal axis thereof, said commissural posts structured to collapse from a position along said horizontal axis to a position along a substantially vertical axis and adapted to position the prosthetic valve during surgical implantation.

2. The valve holder assembly of claim 1, further comprising a stentless heart valve prosthesis positioned within the secondary valve holder.

3. The valve holder assembly of claim 2, further comprising a stentless aortic heart valve prosthesis having a suturing ring.

4. The valve holder assembly of claim 1, wherein the secondary valve holder is attachable to the main valve holder with one or more sutures.

5. The valve holder assembly of claim 1, wherein the main valve holder and the secondary valve holder are formed from metal.

6. The valve holder assembly of claim 1, wherein the main valve holder and the secondary valve holder are formed from plastic.

7. A valve holder assembly for holding and positioning a prosthetic valve during surgical implantation comprising:

a generally cylindrical main valve holder having a top member, a ring base, and a plurality of support members extending between the main valve holder top member and the ring base, the main valve holder adapted to hold the prosthetic valve; and

a secondary valve holder configured to removably nest within the main valve holder, the secondary valve holder comprising;

a substantially flat, disc-shaped top member;

a rotational axle coupled to said secondary valve holder top member;

a plurality of elongated commissural posts extending radially from the top member and the rotational axle along a substantially horizontal axis thereof, said commissural posts structured to collapse from a position along said substantially horizontal axis to a position along a substantially vertical axis and adapted to position the prosthetic valve during surgical implantation.

8. The valve holder assembly of claim 7, wherein the top member of the main valve holder further comprises an aperture adapted to receive a handle.

9. The valve holder assembly of claim 7, wherein the secondary valve holder is securable to the main valve holder with one or more sutures.

10. The valve holder assembly of claim 7, wherein the prosthetic valve is a stentless heart valve prosthesis.

11. A valve holder assembly comprising:

a first generally cylindrical valve holder having a top member, a generally cylindrical ring base, a hollow body portion, and a plurality of strut support members surrounding the hollow body portion, each strut support member coupled on a first end to the first valve holder top member and on a second end to the generally cylindrical ring base;

a second valve holder having a substantially similar centerline to the first valve holder and configured to removably nest within the hollow body portion of the first valve holder, the second valve holder adapted to be sutured to the first valve holder and comprising;

a substantially flat, disc-shaped secondary valve holder top member;

a plurality of elongated commissural posts extending radially from said top member along a substantially horizontal axis thereof, said plurality of elongated commissural posts structured to collapse from a position along said horizontal axis to a position along a substantially vertical axis and adapted to position the prosthetic valve during surgical implantation; and

a prosthetic valve configured to be implanted in a heart, the prosthetic valve having a suture ring and a plurality of commissural valve tabs, wherein the suture ring is adapted to be sutured to the first valve holder and the valve tabs are adapted to be sutured to the plurality of elongated commissural posts of the second valve holder during implantation of the prosthetic valve.

12. The valve holder assembly of claim 11, wherein the second valve holder has three commissural posts.

13. The valve holder assembly of claim 12, wherein the commissural posts are spaced about 120 degrees from one another.

14. The valve holder assembly of claim 11, wherein the commissural tabs of the prosthetic valve are structured for attachment to an aortic wall of the heart.

15. The valve holder assembly of claim 14, wherein the suture ring of the prosthetic valve is structured for attachment to an aortic annulus of the heart.

16. The valve holder assembly of claim 11, wherein the top member of the first valve holder comprises an aperture adapted to receive a handle.

17. The valve holder assembly of claim 16, wherein the aperture and the handle are threaded.

18. The valve holder assembly of claim 11 wherein said secondary valve holder includes a secondary valve holder handle operably coupled to said secondary valve holder top member for removably collapsing said secondary valve holder.
