A crimping device for crimping a stent onto the inflation balloon of a stent delivery catheter. The device forms a crimp which creates regions of high frictional resistence between the stent and the inflation balloon. In one form, the crimp comprises a plurality of spaced grooves running the longitudinal length of the stent. In another form, the crimp is composed of a plurality of radial indentations spaced along the body of the stent. The device including an inner hub housing a plurality of radially spaced crimping jaws and an outer hub enclosing the jaws.
