Methods and systems for performing thoracoscopic coronary bypass and other procedures
First Claim
1. A method for cardiac surgical intervention, said method comprising:
- forming at least one percutaneous penetration in the patient'"'"'s chest;
viewing a portion of the heart through a viewing scope disposed through a percutaneous penetration;
preventing blood from flowing from the patient'"'"'s heart through the aorta at a location within the ascending aorta between the brachiocephalic artery and the coronary ostia;
establishing cardiopulmonary bypass; and
performing a surgical procedure on the heart using tools introduced through a percutaneous penetration while viewing at least a portion of the heart through the viewing scope.

Abstract
A method for closed-chest cardiac surgical intervention relies on viewing the cardiac region through a thoracoscope or other viewing scope and endovascularly partitioning the patient'"'"'s arterial system at a location within the ascending aorta The cardiopulmonary bypass and cardioplegia can be induced, and a variety of surgical procedures performed on the stopped heart using percutaneously introduced tools. The method of the present invention will be particularly suitable for forming coronary artery bypass grafts, where an arterial blood source is created using least invasive surgical techniques, and the arterial source is connected to a target location within a coronary artery while the patient is under cardiopulmonary bypass and cardioplegia.
