Stent-graft and method for detecting a change in pressure differential across the stent-graft
WO 2003096936 A3
Abstract
An endoluminal device (20) for deployment in a body lumen includes a radially expandable stent (30), a graft attached to the stent, and a plurality of indicator members (50) 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 (70) 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.
