Abstract
A multi-catheter emboli containment system is disclosed in which a treatment chamber within a blood vessel is formed by at least two occlusion balloons on opposite sides of a stenotic lesion, thereby preventing emboli migration during the treatment procedure. Irrigation and aspiration are provided to remove emboli and debris from the chamber. The irrigation and aspiration can be provided through separate catheters, or, the catheters used to create the chamber, together with the catheter used to provide therapy to the stenosis can be used. The catheters are all sized so as to be concentric, slidably disposed with respect to one another, and able to be delivered into blood vessels less than 25 mm in diameter or even smaller.
