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 method for forming a coronary artery bypass within a chest of a patient, the chest having a sternum and a plurality of ribs, each rib being separated from an adjacent rib by an intercostal space, the method comprising the steps of:

creating at least one opening in the patient'"'"'s chest through at least one intercostal space;

forming one of an arterial blood source and a graft;

connecting one of the arterial blood source and the graft to a location in a coronary artery downstream from an occlusion therein with at least one tool introduced through one of the at least one opening.

2. The method of claim 1, comprising the step of creating an incision in the coronary artery using a cutting instrument.

3. The method of claim 2, wherein the step of creating an incision comprises passing at least a distal end of a cutting tool through one of the at least one percutaneous penetration.

4. The method of claim 1, wherein the step of forming one of an arterial blood source and a graft comprises introducing at least a distal end of a cutting tool through one of the at least one opening and transecting an artery to form a free end.

5. The method of claim 4, the artery is one of the left internal mammary artery, the right internal mammary artery end the gastroepiploic artery.

6. The method of claim 1, wherein the step of forming one of an arterial blood source and a graft comprises providing a graft harvested from the patient from a location outside the thorax of the patient and introducing the graft through one of the at least one opening.

7. The method of claim 6, wherein the graft is a vein or artery harvested from the patient.

8. The method of claim 7, wherein the graft is one of the saphenous vein or the radial artery.

9. The method of claim 6, wherein the graft is connected on one end to the aorta and on the other end to the coronary artery.

10. The method of claim 1, wherein the step of forming one of an arterial blood source and a graft comprises providing a synthetic graft and introducing the synthetic graft through one of the at least one opening.

11. The method of claim 1, wherein the coronary artery is one of the left anterior descending coronary artery, the diagonal coronary artery, the circumflex artery/obtuse marginal artery, the ramus intermedius coronary artery, the right coronary artery and the posterior descending artery.

12. The method of claim 1, wherein the connecting step comprises introducing at least a distal end of an anastomosing instrument through one of the at least one opening.

13. The method of claim 1, wherein the ribs and sternum remain intact during each of the steps.

14. The method of claim 1, wherein at least one step is performed while viewing the at least one step through a viewing scope passed at least partially through one of the at least one opening.
