WebApr 1, 1988 · Distal to the bifurcation, flow reversal in the internal carotid artery typically assumed a linear configuration in the center of the vessel, extending from the superficial to the deep wall. Variations of these patterns were common. On the average, flow reversal occupied 33% of the lumen of the carotid bulb and extended for a distance of 14 mm. WebThe only device available that effects constant passive procedural flow reversal is the Gore NPS. The system achieves reversed flow by means of occluding the CCA and ECA with elastomeric balloons. The system is connected to the contralateral femoral vein via the Gore External Filter, creating an arteriovenous shunt.
