A system including a stent further including a plurality of conductive struts disposed within a non-conductive body. The stent is configured to exclude an aneurysm within a blood vessel of a person. In addition, the system includes a first electrode and a second electrode. Further, the system includes a controller coupled to the first electrode and second electrode. The controller is configured to measure an impedance between the first electrode and the second electrode and across tissue surrounding the stent to determine if a leak has occurred between the stent and the aneurysm.
