A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.

A method of crimping a prosthetic valve on a delivery catheter having an inflatable balloon includes releasably attaching a holding mechanism to a shaft of the delivery catheter, wherein the holding mechanism is connected to a crimping device, positioning the prosthetic valve in the crimping device, actuating the crimping device to radially crimp the prosthetic valve onto the balloon or onto the shaft of the delivery catheter at a location adjacent the balloon, and removing the holding mechanism from the delivery catheter after crimping the prosthetic valve.

A device for crimping a radially expandable and collapsible prosthetic valve comprises a coiled wire frame having a longitudinal opening extending from a proximal end to a distal end thereof. The opening has a first state and a second state, the opening in the first state having a first diameter dimensioned to receive the prosthetic valve in an expanded or partially crimped configuration therein, and the opening in the second state having a second diameter dimensioned to receive the prosthetic valve in a crimped configuration. The coiled wire frame has a first end coupled to a first member and a second end coupled to a second member. The first member is movable relative to the second member to convert the coiled wire frame from the first state to the second state.

A system for crimping a prosthetic valve can include a radially compressible collet positioned around the prosthetic valve, a housing positioned around the collet, and a pusher at least partially disposed within the housing. The collet can include a first axial end portion, a second axial end portion, and an intermediate portion therebetween. The first axial end portion can have an outer diameter adjacent the intermediate portion that is greater than an outer diameter of the intermediate portion. The second axial end portion can have an outer diameter adjacent the intermediate portion that is greater than the outer diameter of the intermediate portion. The housing can include a housing internal annular ledge configured to slidably engage the second axial end portion of the collet. The pusher can include a pusher internal annular ledge configured to slidably engage the first axial end portion of the collet.
