This document describes intralumenal stent graft devices with integrated anchor members that are selectively deployable in situ. The deployment of the anchor members is also reversible, to thereby facilitate retrieval of the stent graft device. These stent graft devices are well-suited for sealing and repairing defects in a body lumen wall. Such defects can include, but are not limited to, aneurysms and lumen wall openings. In some embodiments, the intralumenal stent graft devices provided herein are well-suited for use in the GI tract including the colon. That is the case because the integrated anchor members provide the stent graft devices with a high level of migration resistance, whereby the stent grafts can remain resiliently located in a desired position within the GI tract despite the peristaltic movements of the GI tract.
