Abstract

A holder for an artificial heart valve includes a holder body, a handle, and a safety member. The holder body is configured to selectively couple to the heart valve. The handle extends from the holder body. The safety member is spaced apart from the holder body, and extends from the handle and is configured to mate with the heart valve in exactly one orientation. The safety member prevents the holder body from mating with the heart valve in other orientations.

Claims

1. A holder for an artificial heart valve of the type having an inlet, an outlet and a first valve blade providing a first profile in relation to the inlet and a second profile in relation to the outlet, wherein the first profile and the second profile are different, the holder comprising:

a holder body configured to selectively couple to a heart valve;

a handle extending from the holder body; and

a safety member, spaced apart from the holder body, extending from the handle and configured to mate with exactly one of the profiles when the holder body is in abutted contact with the heart valve, wherein the safety member prevents the holder body from mating with the other profile.

2. A holder according to claim 1 further comprising a first part and a second part, assembled with each other through a joint, and wherein the first part includes the handle.

3. A holder according to claim 2 wherein the second part is firmly fixed to the handle by a suture.

4. A holder according to claim 1 wherein the holder has a size and a shape, and the holder is marked by a color corresponding to the size and shape.

5. A holder according to claim 1 including a safety ring detachably mounted to the holder body and configured to surround an exterior of the heart valve, the safety ring having a shape corresponding to a shape of a periphery of the heart valve.

6. A holder according to claim 5 wherein the holder includes a recess and the safety ring includes a projecting part configured to fit into the recess.

7. A holder according to claim 5 wherein the safety ring includes a first fitting element configured to fit a transportation container for transporting a valve of a certain defined valve type and size.

8. A holder according to claim 7 wherein the first fitting element includes a bar configured to fit into a first recess of the transportation container.

9. A holder according to claim 1 wherein the holder body includes a material which is detectable through X-ray or through emission of detectable radiation.

10. A holder according to claim 1 wherein the safety member is configured to fit between the blade of the heart valve and a valve ring of the heart valve.

11. The holder according to claim 1 wherein the heart valve has a first state in which fluid flows through the heart valve, and a second state in which fluid is blocked from flowing through the heart valve, and wherein the safety member mates with the first profile when the valve is in the first state.

12. The holder according to claim 1 wherein the heart valve has a first state in which fluid flows through the heart valve, and a second state in which fluid is blocked from flowing through the heart valve, and wherein the safety member mates with the second profile when the valve is in the second state.

13. The holder according to claim 1 wherein the heart valve includes a second blade and wherein the safety member is configured to fit between the first and second blades.
