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.
Claims10
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.
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.
