Controlled endoprosthetic balloon dilation

A medical assembly includes a balloon-expandable endoprosthesis comprising a plurality of annular stent elements flexibly connected to each other via at least one flexible connection, the endoprosthesis deployable from an undeployed state having an undeployed diameter to a deployed state having a deployed diameter. The medical assembly also includes a catheter assembly including a balloon and a cover along the balloon. The endoprosthesis is positioned coaxially about the balloon and the cover. One or more portions of the balloon and the cover reach an intermediate diameter between the undeployed diameter and the deployed diameter, where the portions of the balloon and the cover are inflated by increasing the inflation pressure within the balloon and maintained substantially near the intermediate diameter until the inflation pressure increases by at least one atmospheric pressure, and the yield strength of the covering is overcome. 一种医疗组件包括球囊可扩张的内置假体，该内置假体包括经由至少一个柔性连接件彼此柔性地连接的多个环状支架元件，该内置假体可从具有未展开直径的未展开状态展开到具有
