Abstract
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.
