A stent crimping tool (22) for firmly and uniformly crimping a stent (10) onto a balloon catheter (14) is constructed from a stationary plate (26) and a sliding platform (28) connected to the stationary plate (26) and slidable linearly relative thereto. A closing plate (36) is hinged to the sliding platform (28) so that it at least partially overlies the stationary plate (26) in a down position, and swings away from the stationary plate (26) to an up position, whereby the stent (10) already having been slightly hand crimped onto the balloon cathether (14) is placed on the stationary plate (26) from a lateral position, and the closing plate (36) is moved to the down position to hold the stent (10) between the closing plate (36) and the stationary plate (26) so that an external force on the closing plate (36) as well as translational motion of the closing plate together crimp the stent (10) onto the balloon catheter (14). The surfaces engaging the stent (10) may be covered by elastomeric pads (40, 42) having ridges (44, 46, 48) corresponding in location to respective rings or cylindrical elements (12) of the stent (10). |
