Assemblies are provided for positioning within a lumen comprising a stent graft； and a sensor positioned on the stent graft. Within certain aspects the sensors are wireless sensors, and include for example one or more fluid pressure sensors, contact sensors, position sensors, pulse pressure sensors, blood volume sensors, blood flow sensors, chemistry sensors (e.g., for blood and/or other fluids), metabolic sensors (e.g., for blood and/or other fluids), mechanical stress sensors and/or temperature sensors.
