System and method for crimping a prosthetic valve

1. A crimping device for crimping a radially expandable and compressible prosthetic valve, the crimping device comprising:

a coiled wire frame comprising a first end, a second end, a proximal end, a distal end, and a longitudinal opening extending between the proximal end and the distal end;

a first member coupled to the first end of the coiled wire frame; and

a second member coupled to the second end of the coiled wire frame, the second member movable relative to the first member,

wherein

the coiled wire frame has a first state and a second state, the opening of the coiled wire frame having a first diameter in the first state and a second diameter in the second state, the first diameter greater than the second diameter, the first diameter dimensioned to receive a prosthetic valve in an expanded or partially crimped configuration, the second diameter dimensioned to receive the prosthetic valve in a crimped configuration, and

the first member is operably movable relative to the second member to convert the coiled wire frame from the first state to the second state.

2. The crimping device of claim 1 , further comprising a housing, the housing enclosing the coiled wire frame, the first member, and the second member.

3. The crimping device of claim 2 , further comprising a proximal end cap.

4. The crimping device of claim 2 , further comprising a distal loader.

5. The crimping device of claim 1 , further comprising a screw knob, the screw knob operable for moving the first member relative to the second member.

6. A system for crimping a prosthetic valve, the system comprising:

the crimping device of claim 1 in the first state; and

a prosthetic valve in an expanded or partially crimped configuration positioned in the opening in the coiled wire frame.

7. The system of claim 6 , further comprising sterile packaging, the crimping device and prosthetic device disposed in the sterile packaging.

8. A method for crimping radially expandable and compressible prosthetic valve, the method comprising:

reducing a diameter of an opening extending from a proximal end to a distal end of a coiled wire frame in which a prosthetic valve in an expanded or partially crimped configuration is disposed, thereby crimping the prosthetic valve.

9. The method of claim 8 , wherein reducing a diameter of the opening comprises moving a first member relative to a second member, the first member coupled to a first end of the coiled wire frame, and the second member coupled to a second end of the coiled wire frame.

10. The method of claim 9 , wherein moving the first member relative to the second member comprises rotating a screw knob.

11. The method of claim 8 , further comprising positioning the prosthetic valve in the expanded or partially crimped configuration within the opening of the coiled wire frame.

12. The method of claim 11 , wherein positioning the prosthetic valve comprises positioning the prosthetic valve mounted on a delivery catheter, thereby crimping the prosthetic valve onto the delivery catheter.

13. The method of claim 8 , further comprising releasing the crimped prosthetic valve from the coiled wire frame.

14. The method of claim 13 , further comprising retracting the crimped prosthetic valve proximally.

15. The method of claim 13 , further comprising advancing the crimped prosthetic valve through a loader.
