A stent assembly comprises a rotatable sheath (102) and a stent (120). The assembly is crimped or reduced in diameter prior to loading onto a catheter by one or more crimping apparatuses (510). One crimping apparatus comprises a blade (512) having a stepped configuration. A mandrel (520) may be used to support the assembly during crimping. The mandrel may have an expandable region. A protective sheath (550) may be used to protect the stent during crimping and to redirect the crimping forces to desired locations about the assembly.
Le stent (120) est revêtu d'une gaine tournante (102), et avant de le charger sur un cathéter, on le comprime ou on en réduit le diamètre à l'aide d'un ou de plusieurs appareils ad hoc (510) dont l'un d'eux comporte une lame (512) en escalier. On peut utiliser pour tenir le stent pendant sa compression un mandrin (520) pouvant présenter une partie expansible, ainsi qu'une gaine (550) le protégeant pendant sa compression et redirigeant les forces de compression vers des point désirés de sa périphérie.
