A coaxial catheter system for containment of distal embolization is describ
ed, Utilizing a novel 0.014" hypotube with a distal elastomeric occlusion b
alloon, the PercuSurge GuardWire functions as a guidewire while trapping di
stal embolization resulting from more proximal intervention. The particulat
e debris is evacuated with a single operator exchange aspiration catheter (
Export catheter) prior to deflation of the distal occlusion balloon, This a
nimal study confirmed the feasibility of concept, The system was easily del
ivered through tortuous coronary anatomy. The GuardWire served as an adequa
te rail for delivery of dilatation balloons and a multitude of stents, Ther
e was no evidence of deep wall damage from low-pressure inflation and appos
ition of the distal occlusion balloon, Cathet Cardiovasc. Intervent 47:243-
