Abstract

A prosthetic heart valve holder includes a valve holder selectively attachable with a handle assembly. The handle assembly includes a handle end, a flexible, medial segment, and a coupling member. The valve holder includes a valve coupling member and a handle receiving member. The valve coupling member may include a leaflet bias member, leaflet guards, or both. The handle receiving member includes locking tabs and receiving windows for receiving the handle coupling member. The handle receiving member also includes anti-rotation stays which serve to transfer rotational forces from the handle assembly to the valve holder. Also, alignment stays serve to properly align the handle receiving member with the coupling member so that the handle assembly and valve holder are properly coupled. The handle assembly is made from resterilizable materials so that the handle assembly may be reused. The valve holder is disposable.

Claims

1. A prosthetic heart valve holder, comprising:

a heart valve coupling member operably connected with a handle receiving member, wherein the handle receiving member comprises an annular receiving neck, generally opposed locking tabs positioned on an inner surface of the receiving neck, generally opposed interior walls on the receiving neck defining receiving windows, generally opposed anti-rotation stays spaced axially from the receiving windows, and a plurality of alignment stays spaced axially from the receiving windows.

2. The heart valve holder of claim 1, wherein the handle receiving member further comprises a suture groove in an outer surface of the receiving neck extending generally orthogonal to the longitudinal axis of the receiving neck, a suture cutting groove in the outer surface of the receiving neck positioned orthogonal to and intersecting with the suture groove, and opposed cutting guides positioned adjacent the cutting groove.

3. The heart valve holder of claim 1, further comprising generally opposed suspension grooves in an outer surface of the receiving neck.

4. The heart valve holder of claim 1, further comprising generally opposed finger pads coupled with an outer surface of the receiving neck and circumferentially spaced from the locking tabs.

5. The heart valve holder of claim 1, further comprising a handle alignment indicator positioned on an outer surface of the receiving neck.

6. The heart valve holder of claim 1, wherein the heart valve coupling member comprises an annular disk and a cross member extending from one side of the disk to a generally opposite side.

7. The heart valve holder of claim 6, further comprising a plurality of suture eyelets positioned on the cross member.

8. The heart valve holder of claim 6, wherein the heart valve coupling member further comprises a leaflet bias member.

9. The heart valve holder of claim 6, wherein the heart valve coupling member further comprises generally opposed leaflet guards.

10. The heart valve holder of claim 1, further comprising a handle assembly selectively attachable with the handle receiving member.

11. The heart valve holder of claim 10, wherein the handle assembly is made from materials that are repeatedly sterilizable.

12. The heart valve holder of claim 10, wherein the handle assembly comprises a handle end, a medial segment, and a coupling assembly.

13. The heart valve holder of claim 12, wherein the coupling assembly comprises a generally annular body, generally opposed locking rings extending radially outward from the annular body, generally opposed anti-rotation grooves extending between the locking rings, and a plurality of alignment grooves extending axially along the locking rings.

14. The heart valve holder of claim 13, further comprising an alignment indicatorpositioned on an outer surface of the annular body.
