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 stationary disk and a drive disk for imparting movement to a number of wedges attached to linear sliders on the stationary disk. As rotational movement is imparted by the drive disk to the wedges, the wedges move in a linear direction to form a crimping motion for use in crimping an intravascular intraluminal device onto a catheter or a mandrel. Alternatively, the same motion of the wedges is used to measure the radial strength of an intraluminal device.
