Abstract:
A combination tool for crimping a stent onto a catheter and the stent, the combination comprising: the tool having a cylindrical body having a gripping end and a collet end, wherein the cylindrical body at the collet end transitions into a plurality of segmented jaws that are flared outward to receive the stent therein; external threads disposed on the cylindrical body in between the collet end and the gripping end; a collar rotatably mounted on the cylindrical body having an internal threaded opening engaging the external threads on the body and a front inside diameter of the internal threaded opening engages the plurality of segmented jaws; wherein advancing the collar along the threads translates the front inside diameter over the segmented jaws to converge the segmented jaws into a closed state; and a groove formed along a length of each jaw engaging the stent, wherein when the plurality of segmented jaws are in the closed state, the grooves collectively form a cylindrical cavity leading to an opening at the collet end of the cylindrical body; whereby closing the segmented jaws onto the stent mounted on the catheter, when the stent and catheter are situated within the cavity, crimps the stent onto the catheter.
