Abstract

A stent compression unit has two rows of radial compression rollers (12) with spherical compression faces (16) of decreasing diameter and separation driven by a motor (36) through worm (26) and gears (30) creating a cavity (2) through which the stent is fed into a catheter. Includes an INDEPENDENT CLAIM for compression surfaces of constant cross section.
