A specialist surgical instrument, the 10 1/4" Parsonnet Aorta Clamp – Jaw 1 1/4" is mostly used for aortic occlusion during cardiothoracic procedures, including coronary artery bypass grafting (CABG), aortic valve replacements, and repairs of aortic aneurysms. The 1 1/4-inch jaw size of the clamp guarantees accurate control of the aorta and other major arteries, providing safe vascular occlusion with the least amount of damage possible.
