Abstract:
An endovascular aneurysm occlusion device comprising:a catheter including an outer tubular member having a proximal end, a distal end and a lumen extending therethrough, said catheter also including an inner tubular member having a proximal end, a distal end and a lumen extending therethrough, said inner tubular member being coaxially disposed within the lumen of the outer tubular member; a balloon assembly including an outer balloon having an outer wall defining an interior region and an inner balloon having an outer wall defining an interior region, said inner balloon being disposed within the interior region of the outer balloon; said balloon assembly also including a valve assembly, said valve assembly extending through the wall of the outer balloon and an adjacent portion of the wall of the inner balloon, said valve assembly having a passageway therethrough and a valve means disposed in the passageway, the distal end of the outer and inner tubular members of the catheter extends into the passageway, said valve means being operative to permit the passage of the catheter through the valve assembly but preventing the flow of fluid through said valve assembly when the catheter is withdrawn from said valve assembly; and, a hub having a first lumen and a second lumen, each lumen extending through a hub connector, said hub being mounted to the proximal end of the outer tubular member and the proximal end of the inner tubular member such that the first lumen of the hub is in fluid communication with the lumen of the outer tubular member and the second lumen of the hub is in fluid communication with the lumen of the inner tubular member.
