1. An endograft valve device, comprising:

  • an endograft body configured for expansion from a collapsed configuration to an expanded configuration within a luminal organ, the endograft body comprising;

    a first portion having a proximal end defining a proximal end aperture and a distal end defining a distal end aperture, the first portion tapering toward the distal end so that the distal end aperture has a relatively smaller cross-sectional area than the proximal end aperture when the valve device is expanded; and

    a valve portion positioned at or near the distal end of the first portion, the valve portion configured to receive fluid flowing through the distal end aperture of the first portion.
