    • The invention provides an endovascular device (20) for partitioning the ascending aorta and a system for arresting the heart to facilitate the performance of procedures such as heart valve replacement or coronary artery bypass grafting without the need for a thoracotomy. According to the invention, an endovascular device (20) for partitioning a patient's ascending aorta comprises a flexible shaft (22) having a distal end (24), a proximal end (26), and a first inner lumen (29) therebetween with an opening (31) at the distal end (24). The shaft (22) may have a preshaped distal portion (32) with a curvature generally corresponding to the curvature of the patient's aortic arch. Expandable means (28) are disposed near the distal end (24) of the shaft (22) proximal to the opening (31) in the first inner lumen (20) for occluding the ascending aorta so as to block substantially all blood flow therethrough for a plurality of cardiac cycles. Means (90) for delivering cardioplegic fluid may be connected to the proximal end (26) of the device to infuse cardioplegic fluid into the coronary arteries for arresting the heart. The endovascular device of the invention is readily positionable in the ascending aorta, resists displacement caused by systolic blood flow, and maintains axial alignment with the center of the ascending aorta and aortic valve.

    • The invention provides a system and method for establishing cardiopulmonary bypass and performing an interventional procedure in a patient's heart or great vessel with a minimum of arterial and venous penetrations. In one embodiment, a bypass cannula (180) configured for introduction into a patient's artery includes a blood flow lumen (188) which may be connected to a cardiopulmonary bypass system (92,94,96,100). A catheter shaft (202) is coupled to the bypass cannula, usually within the blood flow lumen, and has a member (216) at its distal end for performing an interventional procedure within the heart or great vessel. In a particular embodiment, the catheter shaft has an expandable member such as an inflatable balloon disposed near its distal for occluding the ascending aorta so as to substantially block all blood flow therethrough for a plurality of cardiac cycles. The catheter shaft has an inner lumen (212) through which cardio-plegic fluid may be delivered upstream of the occluding member to infuse cardio-plegic fluid into the coronary arteries for arresting the heart. The blood flow lumen in the bypass cannula is connected to a cardiopulmonary bypass system, which receives deoxygenated blood from the patient's venous system, oxygenates the blood, and delivers the oxygenated blood to the patient's arterial system through the blood flow lumen.
    • 本发明提供一种用于建立心肺分流术并在患者的心脏或大血管中进行介入手术的系统和方法,其具有最小的动脉和静脉穿刺。 在一个实施例中,配置用于引入到患者动脉中的旁路插管(180)包括可以连接到体外循环系统(92,94,96,100)的血流腔(188)。 导管轴(202)通常在血流腔内联接到旁路插管,并且在其远端具有用于在心脏或大容器内进行介入手术的构件(216)。 在特定实施例中,导管轴具有可膨胀构件,例如设置在其远端附近的可膨胀气囊,用于闭塞升主动脉,以便基本上阻挡通过其中的所有血液流过多个心动周期。 导管轴具有内腔(212),心脏 - 皮肤液体可以通过该内腔(212)被输送到阻塞构件的上游,以将心脏 - 止血液注入冠状动脉以阻止心脏。 旁路插管中的血流腔连接到心肺旁路系统,其接收来自患者静脉系统的脱氧血液,使血液充氧,并通过血流腔将氧合血液输送到患者的动脉系统。

    • A catheter system and devices for achieving total cardiopulmonary bypass during heart surgery are provided. The venous perfusion catheter has first and second balloons occluding the inferior and superior vena cava thereby precluding blood flow into the right atrium. An arterial perfusion catheter is inserted, advanced and positioned in the ascending aorta cephalid of the junction of the coronary arteries with the aortic root. A second flexible arterial cannula is mounted in sliding relationship with the first flexible cannula and carries an inflatable balloon adjacent its distal end to provide for occlusion of the ascending aorta. A first flexible cannula has a first lumen and an arterial venting orifice communicating with the first lumen defining a single flow path for the passage of cardioplegia solution to arrest the heart or for the evacuation of blood from the aortic root. A third lumen extends axially through the first flexible arterial cannula and communicates with a multiplicity of openings in the distal tip for suctioning blood from the left ventricle. The second flexible cannula of the arterial perfusion catheter has a first cavity extending axially therethrough that communicates with an opening at its distal tip to permit the passage of blood delivered by the cardiopulmonary bypass pump into arterial circulation. Both the venous and arterial perfusion catheters have a plurality of radially and oppositely spaced steering lumens and a plurality of steering cables fixed to the distal ends to achieve omnidirectional articulation.
