An assembly is provided which can crimp or compress an intraluminal device or measure the radial strength of an intraluminal device. The device includes a first disk and a second disk for imparting movement to a number of spaced apart moving elements attached to linear sliders on the first disk. In one configuration, rotational movement is imparted to the second disk which causes the tips of the moving elements to move is a linear direction toward the center of the opening formed by the elements thereby closing in on the device. In another configuration, rotational movement is imparted to the first disk and the tips move along an arcuate path from the perimeter of the opening toward the center of the opening.
