Fugitive plasticizer balloon surface treatment for enhanced stent securement

摘要

In an assembly of a balloon mounted on a catheter and a stent mounted over the deflated balloon, the balloon is provided with a fugitive plasticizer before the stent is crimped over the balloon. The fugitive plasticizer can soften the balloon surface so that molding of the balloon surface to conform to the crimped stent occurs. The fugitive plasticizer is removed before the assembly is used.
