Abstract

A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis; disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.

Claims

1-18. -18. (canceled)

19. A method comprising:

engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of said handle;

rotating said hub assembly to cause axial translation of said hub assembly and a sheath coupled to said hub assembly;

disengaging said hub assembly from said threaded outer surface by pivoting a thread tooth of said hub assembly out of threaded engagement with said threaded outer surface; and

sliding said hub assembly on said slide shaft to further retract said sheath.

20. The method of claim 19 wherein said disengaging comprises pulling a thumb slider of said hub assembly.

21. The method of claim 20 wherein said pulling comprises sliding a thread tooth press member across said thread tooth.

22. The method of claim 21 wherein said thread tooth press member pivots said thread tooth as said thread tooth press member is slid past a thread tooth pivot support pivotally coupled to said thread tooth.
