Abstract

A prosthetic heart valve rotator tool includes an operator actuated member and a rotator engageable with a prosthetic heart valve for selectively rotating the prosthetic heart valve. An elongated bendable member has a first end secured to the operator actuated member and a second end secured to the rotator. The elongated bendable member transfers torque between the operator actuated member and the rotator. A covering member covers at least a portion of the elongated bendable member.

Claims

1. A prosthetic heart valve rotator tool comprising:

a rotator adapted to engage a prosthetic heart valve and selectively rotate the prosthetic heart valve;

an elongated bendable member having a first end and a second end secured to the rotator, wherein the elongated bendable member is rotatable over a length of the elongated bendable member from the first end to the rotator with rotation of the first end to transfer torque to the rotator when an axis of rotation of the first end is not aligned with an axis of rotation of the rotator; and

a collar coupled to the elongated bendable member, the collar being rotatable about the elongated bendable member and slidable along the elongated bendable member to and from a position proximate the second end at least a distance of approximately one-half an axial length of the collar and independent of a position of the collar along the elongated bendable member.

2. The prosthetic heart valve rotator tool of claim 1 wherein the collar includes opposed planar surfaces adapted to be held by a surgeon.

3. The prosthetic heart valve rotator tool of claim 1 wherein the elongated bendable member comprises a coiled wire assembly.

4. The prosthetic heart valve rotator tool of claim 3 wherein the coiled wire assembly comprises a plurality of strands.

5. The prosthetic heart valve rotator tool of claim 3 and further comprising a covering member covering the coiled wire assembly and being rotatable with the coiled wire assembly, wherein the collar is rotatable and longitudinally slidable over the covering member.

6. The prosthetic heart valve rotator tool of claim 1 wherein the elongated bendable member is made from a pliable material allowing the elongated bendable member to be shaped from a first configuration to a second configuration, the elongated bendable member substantially maintaining the second configuration after removal of a shaping force.

7. The prosthetic heart valve rotator tool of claim 6 wherein the elongated bendable member comprises a substantially solid shaft.

8. The prosthetic heart valve rotator tool of claim 1 wherein the elongated bendable member includes a tip at the second end, and wherein the rotator engages the tip and is removable from the tip.

9. The prosthetic heart valve rotator tool of claim 8 and further comprising a pin extending from the tip to transfer torque to the rotator.

10. The prosthetic heart valve rotator tool of claim 1 and further comprising an operator actuated member secured to the first end.

11. The prosthetic heart valve rotator of claim 10 wherein the operator actuated member, the rotator, the elongated bendable member and the collar are adapted for sterilization.

12. A prosthetic heart valve rotator tool comprising:

rotator adapted to engage a prosthetic heart valve and selectively rotate the prosthetic heart valve;

an elongated bendable member having a first end and a second end secured to the rotator, wherein the elongated bendable member is rotatable over a length of the elongated bendable member from the first end to the rotator with rotation of the first end to transfer torque to the rotator when an axis of rotation of the first end is not aligned with an axis of rotation of the rotator; and

a bendable tube covering a portion of the elongated bendable member, the tube being rotatable about the elongated bendable member and slidable along the elongated bendable member independent of a position of the tube along the elongated bendable member.

13. The prosthetic heart valve rotator tool of claim 12 wherein the elongated bendable member comprises a substantially solid shaft.

14. The prosthetic heart valve rotator tool of claim 12 wherein the elongated bendable member includes a tip at the second end, and wherein the rotator engages the tip and is removable from the tip.

15. The prosthetic heart valve rotator tool of claim 12 and further comprising an operator actuated member secured to the first end.

23. The prosthetic heart valve rotator tool of claim 12 wherein the tube is made from a pliable material allowing the tube to be shaped from a first configuration to a second configuration, the tube substantially maintaining the second configuration after removal of a shaping force.

16. A prosthetic heart valve rotator tool comprising:

a rotator adapted to engage a prosthetic heart valve and selectively rotate the prosthetic heart valve; and

an elongated bendable member having a first end and a second end, the second end having an axis of rotation, the rotator being secured to the second end with a coupling having an axis, the coupling consisting of a direct connection between the second end and the rotator such that an axis of rotation of the rotator is aligned with the axis of the coupling and the axis of rotation of the second end and wherein the elongated bendable member is rotatable over a length of the elongated bendable member to transfer torque from the first end to the rotator when an axis of rotation of the first end is not aligned with the axis of rotation of the rotator.

17. The prosthetic heart valve rotator tool of claim 16 wherein the elongated bendable member comprises a wire assembly having a plurality of strands.

18. The prosthetic heart valve rotator tool of claim 17 and further comprising a covering member over the wire assembly from proximate the first end to proximate the second end.

19. The prosthetic heart valve rotator tool of claim 18 wherein the covering member is rotatable with the wire assembly.

20. The prosthetic heart valve rotator tool of claim 17 and further comprising a tubular member enclosing a plurality of turns of the wire assembly.

21. The prosthetic heart valve rotator tool of claim 16 and further comprising an operator actuated member secured to the first end.

22. The prosthetic heart valve rotator tool of claim 16 and further comprising a collar rotatable about and slidable along the elongated bendable member.

24. A prosthetic heart valve rotator tool comprising:

a rotator adapted to engage a prosthetic heart valve and selectively rotate the prosthetic heart valve;

an elongated bendable member having a first end and a second end secured to the rotator, wherein the elongated bendable member is rotatable over a length of the elongated bendable member from the first end to the rotator with rotation of the first end to transfer torque to the rotator when an axis of rotation of the first end is not aligned with an axis of rotation of the rotator; and

a collar coupled to the elongated bendable member, the collar being rotatable about the elongated bendable member and slidable along the elongated bendable member independent of a position of the collar along the elongated bendable member within a limited extent from a first position proximate the first end to a second position proximate the second end.
