1. A device for crimping a prosthetic heart valve from a radially expanded arrangement to a compressed arrangement, the device comprising:
a delivery sheath defining a lumen configured to slidingly receive a delivery device with the prosthetic heart valve coupled thereto and a distal portion of the delivery sheath defining an opening, wherein the delivery sheath is configured to be transluminally advanced in situ within a patient's vasculature to a treatment site within a patient's heart and wherein the distal portion is configured for positioning at the treatment site; and
a loading cone coupled to a proximal end of the delivery sheath, the loading cone defining an opening in fluid communication with the lumen, wherein the loading cone is configured to receive the prosthetic heart valve when coupled to the delivery device in the radially expanded arrangement and compress the prosthetic heart valve into the compressed arrangement as the prosthetic heart valve and the delivery device are advanced distally through the loading cone, and
wherein grooves extend along an interior surface of the loading cone.
