System and method for crimping a prosthetic heart valve

A method for crimping a prosthetic valve, the method comprising:

• receiving a prosthetic valve pre-assembled within a crimping device in a sterile package, wherein the crimping device comprises a crimping loop, a first member, a second member, and a threaded screw knob, wherein the crimping loop has a first end portion coupled to the first member, a second end portion coupled to the second member, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve;
• removing the crimping device and valve from the sterile package;
• using the crimping device, crimping the valve to a delivery configuration onto a delivery catheter, wherein crimping the valve comprises reducing a diameter of the opening of the crimping loop by rotating the threaded screw knob of the crimping device, wherein rotating the threaded screw knob is effective to apply opposingly directed forces to the first member coupled to the first end portion of the crimping loop and the second member coupled to the second end portion of the crimping loop and move the first member in a direction perpendicular to a longitudinal axis of the prosthetic valve, thereby radially compressing the valve from a partially crimped configuration to the delivery configuration with the valve mounted on the delivery catheter;
• and
• releasing compression on the valve from the crimping device.
