Abstract

A heart valve prothesis rotator which also has an annealed stainless steel shaft which can be bent by the surgeon interoperatively. The shaft will retain its shape after bending. Surrounding the shaft is a drive coil which connects a rotator head at a proximal end of the shaft to a drive knob at a distal end of the shaft and adjacent a handle. By turning the drive knob, a surgeon can turn the rotator head, thus orienting the prosthetic heart valve. Torsional motion is carried along the path defined by the bendable shaft so that the rotator head can be turned without displacing the handle of the heart valve rotator.

Claims

1. A rotator for a mechanical heart valve comprising

a handle,

a shaft attached to a proximal end of said handle,

a rotator head adapted to engage an annular valve body within said mechanical heart valve, said rotator head being rotatably attached to a proximal end of said shaft, and

a coil attached to said rotator head and extending along said shaft for turning said rotator head.

2. The rotator according to claim 1 further comprising a knob secured to a distal end of said coil.

3. The rotator according to claim 2 wherein said knob is rotatably secured around said shaft adjacent said proximal end of said handle.

4. The rotator according to claim 3 wherein said rotator head has an internal bore and said shaft has retainer means at said proximal end thereof for securing said rotator head, said retainer means being within said bore.

5. The rotator according to claim 4 wherein said rotator head further comprises at least one surface for engaging at least one leaflet in said mechanical heart valve.

6. The rotator according to claim 1 wherein said shaft is bendable.

7. The rotator according to claim 6 further comprising a knob secured to a distal end of said coil.

8. The rotator according to claim 7 wherein said knob is rotatably secured around said shaft adjacent said proximal end of said handle.

9. The rotator according to claim 8 wherein said rotator head has an internal bore and said shaft has retainer means at said proximal end thereof for securing said rotator head, said retainer means being within said bore.

10. The rotator according to claim 9 wherein said rotator head further comprises at least one surface for engaging at least one leaflet in said mechanical heart valve.

11. A rotator for a mechanical heart valve comprising

a handle,

a shaft attached to a proximal end of said handle,

means at a proximal end of said shaft for engaging an annular valve body within said mechanical heart valve, and

means for turning said means for engaging without turning said handle or said shaft.

12. The rotator according to claim 11 further comprising means for manually gripping said means for turning.

13. The rotator according to claim 12 wherein said means for gripping is rotatably secured around said shaft adjacent said proximal end of said handle.

14. The rotator according to claim 13 wherein said shaft has means at said proximal end thereof for rotatably securing said means for engaging to said proximal end of said shaft.

15. The rotator according to claim 14 wherein said means for engaging further comprises at least one surface for supporting at least one leaflet in said mechanical heart valve.

16. The rotator according to claim 11 wherein said shaft is bendable.

17. The rotator according to claim 16 further comprising means for manually gripping said means for turning.

18. The rotator according to claim 17 wherein said means for gripping is rotatably secured around said shaft adjacent said proximal end of said handle.

19. The rotator according to claim 18 wherein said shaft has means at said proximal end thereof for rotatably securing said means for engaging to said proximal end of said shaft.

20. The rotator according to claim 19 wherein said means for engaging further comprises at least one surface for supporting at least one leaflet in said mechanical heart valve.
