  • Patent number: 7131447
    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.

  • Patent number: 6783511
    Abstract: A device for delivering oxygenated blood and occluding the ascending aorta is provided. The device has a blood flow lumen with a movable portion. The movable portion is movable from a position contained within a body of the device to a position which extends outwardly from the device. The movable portion is made of a tube of flexible material and everts when moving to the extended position.

  • Patent number: 6699231
    Abstract: Organs and other tissue structures are isolated and perfused with a therapeutic agent. Isolation is effected by endovascularly positioning catheters having occlusion balloons within the arteries or other blood vessels which supply blood to the organ. Similarly, blood flow from the organ back to the patient's circulatory system is blocked by endovascularly positioning one or more catheters carrying occlusion members within the veins or other blood vessels leading from the organ. The therapeutic agent may then be perfused through the organ in either an antegrade or retrograde fashion using the endovascularly positioned catheters while maintaining isolation.

  • Patent number: 5536251
    Abstract: The invention provides devices and methods for thoracoscopically arresting the heart and establishing cardiopulmonary bypass, thus facilitating a variety of less-invasive surgical procedures on and within the heart and great vessels of the thorax. In one embodiment, the invention provides a thoracoscopic system for arresting a patient's heart including a clamp configured for introduction into the patient's thoracic cavity through a percutaneous intercostal penetration in the patient's chest. The clamp is positionable about the patient's ascending aorta between the coronary arteries and the brachiocephalic artery. The clamp is coupled to the distal end of an elongated handle means for manipulating the clamp from a location outside of the patient's thoracic cavity. A means for actuating the clamp is coupled to the proximal end of the handle means. When actuated, the clamp blocks blood flow through the ascending aorta.
