Abstract

A method for performing coronary artery bypass relies on viewing the cardiac region through a thoracoscope or other viewing scope and endovascularaly partitioning the patient'"'"'s arterial system at a location within the ascending aorta. The coronary artery bypass procedures are formed under cardiopulmonary bypass and cardioplegia, where an arterial blood source is created using least invasive surgical techniques.

Claims

1. A method for forming a coronary artery bypass graft in a patient, 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;

forming an arterial blood source;

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; and

connecting the arterial blood source to a location in a coronary artery downstream from an occlusion using tools introduced through a percutaneous penetration while viewing the region of the stopped heart through the viewing scope.

2. A method as in claim 1, wherein the viewing scope is introduced through a trocar sheath disposed in a percutaneous penetration.

3. A method as in claim 1, wherein the arterial blood source is formed by transecting an artery.

4. A method as in claim 3, wherein the transected artery is a mammary artery.

5. A method as in claim 1, wherein the arterial blood source is formed by grafting a natural or synthetic blood vessel to the aorta.

6. A method as in claim 1, wherein the arterial system is partitioned by endovascularly advancing a distal end of a catheter to the location within the ascending aorta, and expanding a blocking element on the catheter at said location to inhibit the flow of blood and other fluids past said location.

7. A method as in claim 6, wherein the heart is stopped by anterograde introduction of cardioplegic fluid into the coronary arteries through the catheter.

8. A method as in claim 1, wherein cardiopulmonary bypass is established from the femoral vein to the femoral artery.

9. A method as in claim 1, wherein the arterial blood source is connected to an incision formed in the coronary artery while the heart remains stopped.

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