1. A prosthesis for monitoring a characteristic of flow, said prosthesis comprising:

  • a first tubular prosthesis having proximal and distal ends; and

    a lumen extending therebetween;

    a second tubular prosthesis having a lumen extending therethrough,a non-optical sensor for detecting a characteristic of fluid flowing through the lumen of the first tubular prosthesis; and

    a layer of material provided over the sensor, sealingly coupling the sensor to a surface of the first tubular prosthesis without embedding the sensor within the first tubular prosthesis, wherein the sensor is insulated from contact with fluid flowing through the lumen;

    wherein the second tubular prosthesis is coaxially mounted to the first tubular prosthesis such that the non-optical sensor is not interposed between the first and second tubular prosthesis.
