<p>A method and apparatus are disclosed for transsternal access (100) to the ascending aorta, the heart and the cardiovascular system for diagnostic, interventional and surgical procedures. A small incision (102) is made over the sternum and a hole (100) is drilled or punched through the sternum using a non-coring or coring drill, typically between the first rib and the second intercostal space, which places the hole (100) over the location of the ascending aorta. The surgical access (100) may also be made through the suprasternal notch or within the parasternal region. The anterior mediastinum is crossed and the lungs are retracted aside to extend the transsternal access channel and to expose the ascending aorta. A transsternal aortic crossclamp (108) may be inserted through the transsternal access channel to occlude the ascending aorta for performing cardiopulmonary bypass and cardioplegic arrest.</p> |
