摘要： A cardioplegia occluder (1) and methods of using the device during cardiac surgery are disclosed. The system typically includes a substantially rigid cannula (3) with an occluder (20) mounted on the distal region of the cannula (14) that expands upon activation to occlude the aorta downstream of an infusion port which delivers cardioplegia solution to arrest the heart. Systems including cutting blades, blade guards, flanges, radiopaque markers and occluder aligners are also disclosed. In use, the distal end of the cannula is inserted through an incision into the aorta, the occluder is expanded and cardioplegia solution is infused upstream of the aorta to arrest the heart. The infusion port can alternately be used to aspirate cardioplegia or embolic debris or other unwanted material from the aorta.

摘要： A method for closed chest cardiac surgical intervention relies on viewing the cardiac region through a thoracoscope (34) or other viewing scope and endovascularly partitioning the patient's arterial system at a location within the ascending aorta. The cardiopulmonary bypass (56) 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.

摘要： A total condensed circuit for cardiopulmonary bypass and cardioplegia are provided, as well as methods of using the same. The total circuit includes a cardiopulmonary bypass portion including tubing and components which together have a substantially short path length and priming volume preferably under 800 ml. Thus, the opportunity for an inflammatory response caused by blood contacting plasticizers is minimized. The bypass circuit includes a shunt which bypasses a blood reservoir of the total circuit. The cardioplegia circuit infuses cardioplegia fluid into blood pulled from an oxygenator of the bypass circuit. According to the method, either or both of heart-lung bypass and cardioplegia can be performed with only minimal or no isotonic priming solution circulated into the patient. In addition, use of the shunt and reservoir together eliminate the possibility of air entering the circulation system upon kinking of the circuit.

摘要： An improved catheter and method for infusing blood to the heart, clamping the aorta and delivering a cardioplegia solution. A single catheter (10, 100) is used having a unique balloon (102, 162, 172) for occluding the aorta (12). In a first embodiment, a single catheter (10) is transthoracically inserted upwardly in the aorta to infuse oxygenated blood into the ascending aorta via an infusion opening (46) terminating at the distal end (32), with cardioplegia solution being delivered via openings (42) defined closely adjacent the balloon (40) on the proximal side of the balloon. In a second and third embodiment, a single catheter (100) is transthoracically and femorally inserted, respectively, inserted into the aorta to infuse blood via openings (102) into the ascending aorta proximate the Brachiocephalie Artery, and deliver cardioplegia solution via the distal opening (104) downward toward the aortic base. A fourth lumen (90, 140) is provided in both catheters for sensing aortic root pressure in combination with a pressure meter (92) to first ascertain if the balloon is sufficiently inflated and properly occluding the aorta, and second to ascertain proper function of the aortic valve during cardioplegia delivery. The balloon (202, 231) is preferably filled with a partitioned resilient material (204) to permit varying diameters of the balloon and occlude body passageways having varying diameters and curvatures, and may be elongated (262) to improve occlusion.

摘要： A method and apparatus for performing coronary perfusion and cardiac reoxygenation that enables accurate control of oxygen levels in blood used for the coronary circulation. Deoxygenation blood and oxygenated blood are collected and oxygen levels are measured by sensors, (420, 425). The deoxygenated and oxygenated blood is then mixed and the mixed blood is measured by another sensor (450). The sensors provide data used to provide real-time oxygen level measurement and adjustment for blood supplied for coronary circulation.

摘要： Systems and methods are disclosed for performing less invasive surgical procedures within the heart. A method for less invasive repair or replacement of a cardiac valve (216) comprises placing an instrument (290) through an intercostal access port (212) and through a penetration in a wall of a vessel in communication with the heart, advancing the instrument (290) into the heart, using the instrument (290) to perform a surgical intervention on a cardiac valve (216) in the heart under visualization through an intercostal access port. The surgeons hands are kept outside of the chest during each step. The surgical intervention may comprise replacing the cardiac valve with a prosthetic valve, wherein the native valve is removed using a tissue removal instrument (206), the native valve annulus is sized with a specialized sizing device (216), a prosthetic valve is introduced through an intercostal access port (212) and through the penetration in the vessel, and the prosthetic valve is secured at the native valve position, all using instruments positioned through intercostal access ports without placing the hands inside the chest. Systems and devices for performing these procedures are also disclosed.

摘要： The invention provides a system and method for performing less-invasive surgical procedures within a body cavity. In a preferred embodiment, the invention provides a system and method for temporarily occluding a blood vessel in an arterial graft in a thoracoscopic coronary artery bypass grafting procedure. The system comprises a clamp (2) and an introducer (1) for introducing the clamp through a percutaneous penetration into the body cavity and applying the clamp to a tissue structure such as a blood vessel. The clamp has a pair of movable jaws (65, 67) coupled to one another, each jaw having a distal portion for engaging the tissue structure and a proximal portion having a camming surface (66, 68). The introducer has a longitudinal shaft (3) with a clamp engaging means (25) slidably coupled to the distal end of the shaft for releasably holding the clamp. A handle (11) is coupled to the proximal end of the shaft. The handle can be manipulated to axially slide the shaft with respect to the clamp engaging means so that the shaft engages the camming surfaces of the clamp to open and close the distal portions of the jaws without releasing the clamp from the introducer.

摘要： The invention provides an endovascular device (20) for partitioning the ascending aorta and a system for arresting the heart to facilitate the performance of precedures 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 (29) 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.
