A coaxial catheter system for containment of distal embolization is described. Utilizing a novel 0.014” hypotube with a distal elastomeric occlusion balloon, the PercuSurge GuardWire functions as a guidewire while trapping distal embolization resulting from more proximal intervention. The particulate debris is evacuated with a single operator exchange aspiration catheter (Export catheter) prior to deflation of the distal occlusion balloon. This animal study confirmed the feasibility of concept. The system was easily delivered through tortuous coronary anatomy. The GuardWire served as an adequate rail for delivery of dilatation balloons and a multitude of stents. There was no evidence of deep wall damage from low‐pressure inflation and apposition of the distal occlusion balloon. Cathet. Cardiovasc. Intervent. 47:243–250, 1999. © 1999 Wiley‐Liss, Inc.
