Methods and apparatuses relate to treating vessels that have developed an aneurysm or vessels that are expected to develop an aneurysm (e.g., aortic aneurysm). The device may include a conduit having one or more coupling members that serve to couple the conduit and the vessel together. The conduit and coupling member(s) may cooperate to apply an inward radial force (e.g., physical pulling of the vessel wall inward) on the vessel wall, substantially preventing vessel enlargement. In some embodiments, coupling members are disposed at a midpoint region between opposite ends of the conduit, such as regularly along the length of the conduit. When deployed, the device reduces the risk of excessive vessel enlargement which may otherwise lead to undesirable rupture or dissection of the vessel.
