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

15. A method for forming an anastomosis between a mammary artery and a coronary artery of a patient, said method comprising:
-
positioning at least one trocar sheath through the patient'"'"'s chest;
introducing a viewing scope through the trocar sheath to view the region around the heart;
collapsing a lung beneath the mammary artery while ventilating the contralateral lung;
transecting the mammary artery using a tool introduced through a trocar sheath while viewing the artery using the viewing scope;
endovascularly partitioning the patient'"'"'s arterial system at a location within the ascending aorta between the brachiocephalic artery and the coronary ostia;
establishing cardiopulmonary bypass;
stopping heart contraction;
collapsing both lungs;
forming an incision in the coronary artery using a cutting tool introduced through a trocar sheath while viewing the artery using the viewing scope while the heart is stopped; and
connecting the transected internal mammary artery to the incision in the coronary artery using a tool introduced through one of the trocar sheaths while viewing the arteries using the viewing scope while the heart is stopped. - View Dependent Claims (16, 17, 18)

19. An improved method for performing coronary bypass in a patient, said method including the steps of creating an arterial blood source and connecting the created arterial blood source to a location in a coronary artery downstream from an occlusion, wherein the improvement comprises performing said steps using percutaneously introduced tools while viewing said steps using a percutaneously introduced viewing scope.
