An implantable prosthetic device for connection to a fluid flow pathway of a patient, the device comprising a biocompatible microporous wall that surrounds an interior space which constitutes a lumen that extends along a longitudinal axis and is adapted for the accommodating fluid flow therethrough, and plural remotely detectable components formed integrally within secondary lumina (216) in said wall to move therewith said secondary lumens (216) formed by extrusion and each extending in a line parallel to said -longitudinal axis, such that said plural remotely detectable components are remotely detectable as lines that move relative to each other with pulsatile motion of the wall as blood flows through the lumen for indicating patency of the lumen. <IMAGE> |
