1. A crimping device for crimping a radially expandable and compressible prosthetic valve, comprising:
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,
wherein 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;
wherein the crimping loop comprises a plurality of non-overlapping coiled rings arranged side-by-side along a longitudinal axis of the prosthetic valve positioned within the loop portion.
