摘要

Disclosed are devices and methods for treatment of aneurysms. In one variation, a device for treating an aneurysm includes a tubular graft comprising a longitudinal channel having a first end and a second end, wherein the longitudinal channel is bifurcated at a bifurcated portion. The device also includes an expandable anchoring member attached to the first end of the longitudinal channel and inflatable chambers on the exterior of the tubular graft. The inflatable chambers are configured to receive a filling medium. At least one of the inflatable chambers is positioned along the longitudinal channel on the side of the bifurcated portion toward the expandable anchoring member and is only partially around the circumference of the longitudinal channel.
