Title: Collet type crimping tool

Abstract: A sterile tool for crimping a stent onto a balloon catheter is disclosed. The stent crimping tool includes two major components, a cylindrical body having external threads and a rotating collar with internal threads engaging the external threads. The collet end of the cylindrical body is split into segmented jaws that are biased to flare outward in an open state. A stent loaded onto a balloon catheter and situated inside the open segmented jaws can undergo a crimping operation when the collar is rotated and advances toward the flared open segmented jaws. When the collar engages the segmented jaws, the jaws are forced to converge and close onto the stent-catheter assembly thereby crimping the stent onto the balloon catheter.
