ABSTRACT:
A stent mounting device and method of using the device comprising a disposable device for holding a stent, into which a delivery system such as a balloon catheter can be inserted, and the stent crimped onto the delivery system, after which the delivery system and mounted stent are removed from the device. A stent is carried in a channel formed by four corner segments of four co-axillay arranged spaced blocks. Two adjacent blocks are elastically mounted in each of two parallel, opposed, cooperating actuators. The corner segments form an elongated channel sized to retain a conventional stent. Two elastic rods are placed between opposite blocks in opposite actuators. When the actuators are pressed together the rods are deformed to provide pressure transverse to the line of pressure, so that the cross sectional area of the channel is decreased in both directions, crimping the stent uniformly onto a delivery system.
