International ClassA61M 29/00AbstractAn occlusion catheter for the ascending aorta capable of obstructing the blood flow within the ascending aorta without inserting through the femoral artery. The occlusion catheter is provided with a drug release aperture formed in the region, which is closer to the proximal end of the catheter tube than a balloon on the outer circumference of the distal end and which is to be located in the vicinity of the coronary ostium when the balloon is placed within the ascending aorta. The present occlusion catheter, when inserted directly into the ascending aorta in the vicinity of the heart to obstruct the blood flow therewithin, enables delivery of a cardiac muscle protective drug to the vicinity of the coronary ostium without inserting the occlusion catheter through the femoral artery in the conventional manner.Field of SearchBody inserted tubular conduit structureHaving means inflated in body (e.g., inflatable nozzle, dilator, balloon catheter, occluder, etc.) Having aperture in conduit proximal of inflated means Lumen extending from aperture proximal of inflated means to distal end Lumen extending from proximal end to aperture proximal of inflated means Having means expanding body orifice or canal (e.g., dilator, retaining means, etc.) Body inserted tubular conduit structure (e.g., needles, cannulas, nozzles, trocars, catheters, etc.) Flexible catheter or means (e.g., coupling) used therewith Internal pressure applicator (e.g., dilator) Inserted in vascular system Inflatable or expandible by fluid | |
