摘要
A device for steering J-tip guidewire through true lumen of artery to puncture site where an occlusion abuts artery wall and stylet wire in lumen of J-tip guidewire provides axis for screwing it between intimal and medial layers of artery wall and stiffens it sufficiently to transform J-tip to loop that dissects a false lumen between intimal and medial layers around occlusion to its end where tamping balloons push aside intimal layer and occlusion so false lumen and true lumen coincide allowing intimal layer to be safely pierced by stylet wire allowing blood flow through previously occluded artery segment.
