Abstract: A system including a delivery apparatus, a crimping device, and a loading assembly. The crimping device includes a housing disposed over a distal end portion of the delivery apparatus for receiving a radially expandable and compressible prosthetic heart valve. The housing includes a funnel segment, a pusher member, and an actuator releasably coupled to the pusher member. Movement of the actuator causes the pusher member to advance the prosthetic heart valve through the funnel segment for radially compressing at least a portion of the prosthetic heart valve. Compression of the prosthetic heart valve facilitates secure attachment of the prosthetic heart valve to the delivery apparatus. The loading assembly can include an additional funnel member for fully crimping and loading the prosthetic heart valve into the delivery apparatus for advancement through a patient's vasculature.
