Abstract: An endograft device includes: an expandable tubular body having an inner side and an outer side of a surrounding wall, the tubular body encloses a lumen, having a first open end and a second open end. A sheath pocket having a pocket wall longitudinally disposed along the tubular body, enclosing a channel. The sheath pocket having an input port disposed proximal to the first open end, and an output port disposed proximal to the second open end. The input port faces towards the first open end to provide an entrance to the sheath pocket. An expandable lining of wire framework, is inserted longitudinally into the lumen such that the lining of wire framework after expansion exerts an outward pressure against the inner side of the surrounding wall and against the pocket wall of the sheath pocket to naturally shut seal both the input port and the output port.
