  • a handle having a plurality of elongate strands attached thereto, the elongate strands being formed of a flexible material;

    a cylindrical element having a tapered bore extending at least partially therethrough, the tapered bore further having an inner diameter substantially defining the diameter of the stent when crimped onto the balloon catheter;

    whereby the elongate strands extend through the tapered bore and inner diameter and the stent is positioned over the balloon portion of the balloon catheter with the elongate strands positioned around the stent and balloon, the stent is crimped onto the balloon as the handle is used to pull the elongate strands through the tapered bore, which in turn crimps the stent around the balloon portion of the catheter.
