Abstract
An endoluminal device including a prosthesis and at least one indicator member affixed to the prosthesis that can be remotely monitored to indicate a change in pressure or morphology of the prosthesis. The indicator member may be an optical fiber, a strain gauge, or a first material having a first magnetic resonance imaging (MRI) susceptibility value that contrasts with a second MRI susceptibility value of a second material that comprises one or more remaining members of the prosthesis. A prosthesis monitoring system includes an endoluminal device as well as a subcutaneous electronics package and external electronics. Methods of detecting endoleaks or changes in morphology involve implanting an endoluminal device with the indicator and detecting information from the indicator.
