When performing cardiothoracic and vascular surgeries that call for aortic occlusion, such as aortic aneurysm repairs, aortic valve replacements, and coronary artery bypass grafting (CABG), the 10 3/4" Cooley Aorta Clamp (Standard) is a highly effective surgical tool that offers excellent control over the aorta and other major vessels during surgery, allowing for temporary occlusion without needlessly damaging the vessel walls.
