Abstract
A system and method for treating a vessel is provided. A catheter system includes an inner elongated element and an outer elongated element positioned coaxially with respect to the inner elongated element. A proximal occlusion element is positioned at and is flush with the distal end of the outer elongated element. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end. One or both of proximal occlusion element and distal occlusion element is a compliant balloon, configured to form a funnel shape upon proximal movement of the outer elongated element and/or the inner elongated element.
