An endoluminal device for deployment in a body lumen includes a radially expandable stent, a graft attached to the stent, and a plurality of indicator members affixed to the graft and adapted to form a normal pattern in response to a normal pressure differential and an abnormal pattern in response to an abnormal pressure differential across the graft. By forming different patterns at different pressure differentials, the indicator members enable the detection of a change in pressure which could be evidence of a leak. A system for detecting a change in pressure differential includes the endoluminal device and an imaging system for displaying the indicator members. A method for detecting a change in pressure includes the steps of identifying the normal pattern, implanting the device, imaging the indicator members, and comparing the imaged pattern with the normal pattern to determine whether the normal pressure or an abnormal pressure differential exists.
An endoluminal device for deployment in a body lumen, the device comprising:
A system for detecting a change in pressure differential across an implanted endoluminal device between an internal pressure at a radially interior space and an external pressure at a radially exterior space, wherein said device comprises a radially expandable stent and a graft attached to said stent, the system comprising:
A method for detecting a change in pressure differential across an endoluminal device between an internal pressure at a radially interior space and an external pressure at a radially exterior space, wherein said endoluminal device comprises a radially expandable stent, a graft attached to said stent, and a plurality of indicator members affixed to said graft and adapted to form a normal pattern in response to a normal pressure differential between the internal pressure and the external pressure and an abnormal pattern in response to an abnormal pressure differential between the internal pressure and the external pressure, the method comprising:
