Abstract
Some embodiments are directed to a stent graft comprising a first stent graft having a first stent, a first inner graft supported by the first stent, a second inner graft supported by the first stent, and an outer graft. The second inner graft can be spaced apart from the first inner graft so that a portion of the first stent is not covered by the first inner graft or the second inner graft. A first and second portion of the outer graft can be attached to the first stent, the outer graft being unsupported by the stent between the first and second portions so as to form a fillable space between the outer graft, the first inner graft, and the second inner graft. Some embodiments further comprise a second stent graft deployable within the inside of the first stent graft to sealingly cover the uncovered portion of the first stent.
