An apparatus for crimping down a radially expandable stent to a pre-determined profile, the apparatus has at least one set of rollers, each set including a first roller having at least a first groove and a second roller also having at least a first groove, the first groove on the first roller having the same dimensions and corresponding in relative location along the roller with the first groove on the second roller. The first groove on the first roller is aligned with the corresponding first groove on the second roller so that the respective first grooves together define an aperture whereby on rotation of the rollers, a stent advanced toward the rollers is drawn into the aperture thereby crimping down the stent to the pre-determined diameter.
