1. A method of reducing a stent in cross-section comprising the steps of:
providing an apparatus for reducing the size of a stent comprising a plurality of movable dies arranged to form a chamber whose size may be varied by moving the dies, the chamber having a length from a first end of the chamber to a second end of the chamber, the dies configurable to provide the chamber with at least a first region and a second region, the cross-section of the first region being different than the cross-section of the second region;
disposing a stent in the chamber;
reducing the size of the chamber so as to shape a first portion of the stent with a first geometric shape and a second portion of the stent with a second geometric shape of a different geometry from the first geometric shape.
