Methods and systems for performing thoracoscopic cardiac bypass and other procedures
First Claim
1. A system for facilitating a closed chest surgical procedure on or around the exterior of a patient'"'"'s heart comprising:
- a scope for viewing the interior of the patient'"'"'s chest cavity which can be inserted through a small opening in the patient'"'"'s chest;
means for occluding the patient'"'"'s ascending aorta at a location between the patient'"'"'s coronary arteries and the brachiocephalic artery;
a cardiopulmonary bypass system, including means to direct oxygenated blood into the patient'"'"'s arterial system downstream from the occluded ascending aorta;
means for inducing cardioplegia; and
surgical tools for operating on and around the external surface of the heart.

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.
