摘要：
A tool for compressing a stented prosthesis. The tool includes first and second sets of rollers. The first set includes a plurality of rollers arranged to define a first working region having a first working diameter. The second set includes a plurality of rollers arranged to define a second working region having a second working diameter. The sets of rollers are arranged such that the working regions are axially aligned. The first working diameter is greater than the second working diameter. A stented prosthesis traversing the first working region and then the second working region is forced to a compressed state. In some embodiments, the tool includes one or more intermediate sets of rollers between the first and second sets of rollers, with each of the intermediate sets of rollers defining a working region having a working diameter. The respective working diameters progressively decrease in a downstream direction.
