  • Aortic balloon catheter assembly for indirect infusion of the coronary arteries
    Patent number: 5167628
    Abstract: A method and apparatus for indirectly infusing the coronary arteries involves insertion of a relatively large tubular member into the left ventricle to maintain blood flow from the left ventricle into the aorta. An isolated chamber within a segment of the aorta encompassing the opening to the coronary arteries is formed by inflating a pair of doughnut-shaped balloons attached at opposite ends of the tubular member. A catheter extends axially through the tubular member and includes a passage for infusing a treatment material into the isolated chamber. The treatment material is subsequently drawn into the coronary arteries which form the only exit from the isolated chamber.

  • Arterial catheter means
    Patent number: 4705507
    Abstract: An arterial catheter of the multi-lumen type having an inflatable balloon portion to wedge the catheter in place against the arterial wall. Multi-infusions are allowed through the segmented multi-lumens. This catheter is so designed to allow blood to flow in the arterial system with the catheter in place. During diastolic phases, the blood flow will be closed off with movable plastic valves.
