Abstract
Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to inflatable stent grafts and methods of positioning and deploying such devices within the body of a patient. Some embodiments include inflation devices and methods that allow an inflatable portion of an inflatable stent graft to be inflated from a desired location within the inflatable portion.
