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.

Claims

1. A system of instruments for performing a procedure on a patient'"'"'s heart comprising:

an occluding member having an expanded shape configured for occluding the patient'"'"'s ascending aorta at a location between the patient'"'"'s coronary arteries and the brachiocephalic artery, the occluding member being a catheter having an expandable member, the catheter being sized and configured for advancement through the patient'"'"'s aorta until the expandable member is disposed between the ostia of the coronary arteries and the brachiocephalic artery, the expandable member being shaped and dimensioned so that the patient'"'"'s ascending aorta is occluded when the expandable member is in an expanded condition;

an anastomosis device for securing a graft to the patient'"'"'s coronary artery downstream from a blockage in the coronary artery, the anastomosis device being configured for introduction into the patient through a percutaneous penetration in the patient'"'"'s chest extending between adjacent ribs; and

means for arresting the patient'"'"'s heart.

2. The system of claim 1 further comprising an arterial return device having a lumen in communication with an outlet, the outlet being positionable in the arterial system downstream of the expandable member, and the lumen being configured to deliver oxygenated blood to the aorta downstream of the expandable member when the heart is arrested.

3. The system of claim 2 wherein the outlet of the arterial return device is independently positionable relative to the occluding member.

4. The system of claim 2 further comprising a venous cannula positionable in a vein for removing venous blood from the patient.

5. The system of claim 4 further comprising an oxygenator having an inlet and an outlet, the inlet being coupled to the venous cannula and the outlet being coupled to the lumen of the arterial return device.

6. The system of claim 1 wherein the means for arresting the heart comprises a delivery lumen which extends through the catheter and is configured to deliver cardioplegic fluid distal to the expandable member so as to arrest the heart.

7. A system of instruments for performing a procedure on a patient'"'"'s heart comprising:

an occluding member having an expanded shape configured for occluding the patient'"'"'s ascending aorta at a location between the patient'"'"'s coronary arteries and the brachiocephalic artery, the occluding member being a catheter having an expandable member, the catheter being sized and configured for advancement through the patient'"'"'s aorta until the expandable member is disposed between the ostia of the coronary arteries and the brachiocephalic artery, the expandable member being shaped and dimensioned so that the patient'"'"'s ascending aorta is occluded when the expandable member is in an expanded condition;

an anastomosis device for securing a graft to the patient'"'"'s coronary artery downstream from a blockage in the coronary artery, the anastomosis device being configured for introduction into the patient through a percutaneous penetration in the patient'"'"'s chest extending between adjacent ribs;

means for arresting the patient'"'"'s heart; and

an arterial return device having a lumen in communication with an outlet, the outlet being positionable in the arterial system downstream of the expandable member, the lumen being configured to deliver oxygenated blood to the aorta downstream of the expandable member when the heart is arrested.
