Disclosed herein are bifurcated endoprosthetic devices, systems, and methods for treating human vasculature diseases. In various embodiments, the bifurcated endoprosthesis includes a trunk portion and a plurality of legs, where the legs are constrained such that they remain aligned with each other. In some examples, legs and bifurcations of an endoprosthetic device may be formed by cutting a tubular graft component in a longitudinal central region along a portion less than an entire periphery thereof and then folding the tubular graft component along an uncut portion defining a bifurcation to define two legs. In some such examples, a folded tubular graft component may be connected with a tubular trunk component to form a bifurcated endoprosthetic device. 本文公开了用于治疗人类脉管系统疾病的分叉式内置假体设备、系统和方法。在各种实施例中，分叉式内置假体包括主干部分和多个腿部，其中腿部被约束成使得它们保持彼此对准。在一些示例中，内置假体设备的腿部和分叉部可通过在纵向中心区域中沿着小于其整个周缘的一部分切割管状移植物部件，然后沿着未切割部分折叠管状移植物部件以限定两个腿部来形成，其中未切割部分限定分叉部。在一些这样的示例中，折叠的管状移植物部件可以与管状主干部件连接，以形成分叉式内置假体设备。
