    Abstract: Device and methods are provided for less invasive surgical treatment of cardiac valves whereby the need for a gross thoracotomy or median sternotomy is eliminated. In one aspect of this invention, a delivery system (10) for a cardiac valve prosthesis such as an annuloplasty ring (90) or prosthetic valve (262) includes an elongated handle (28) configured to extend into the heart through an intercostal space from outside of the chest cavity, and a prosthesis holder (100) attached to the handle for releasably holding a prosthesis. The prosthesis holder (100) is attached to the handle (28) in such a way that the holder (100), prosthesis (90) and handle (28) have a profile with a height smaller than the width of an intercostal space when the adjacent ribs are unrectrated, preferably less than about 30 mm. In a further aspect, the invention provides a method for repairing or replacing a heart valve which includes the steps of introducing a prosthesis (262) through an intercostal space and through a penetration in a wall of the heart, and securing the prosthesis (262) to an interior wall of the heart, wherein each step is carried out without cutting, removing, or significantly retracting the ribs or sternum.

    Abstract: A catheter system is provided for accessing the coronary ostia (176, 180) transluminal from a peripheral arterial access site, such as the femoral artery, and for inducing cardioplegia arrest by direct infusion of cardioplegia solution into the coronary arteries. In a first embodiment, the catheter system is in the form of a single perfusion catheter (20) with multiple distal branches (24, 26, 28) for engaging the coronary ostia (176, 180). In a second embodiment, multiple perfusion catheters (82, 84) are delivered to the coronary ostia (176, 180) through a single arterial cannula (104). In a third embodiment, multiple perfusion catheters (112, 114, 116) are delivered to the coronary ostia (176, 180) through a single guiding catheter (126). In a fourth embodiment, multiple catheters (140, 142, 144) are delivered to the coronary ostia (176, 180) through a single guiding catheter (130) which has distal exit ports (134, 136, 138) that are arranged to direct the perfusion catheters into the coronary ostia (176, 180). In each embodiment, the catheters (20) are equipped with an occlusion means (30, 50) at the distal end of the catheter (20) for closing the coronary ostia (176, 180), and isolating the coronary arteries from the systemic blood flow.

    Abstract: A venting catheter, system and method, are provided for withdrawing blood and other fluids from a patient's heart to facilitate decompressing the heart during cardioplegia arrest and cardiopulmonary bypass, without the need for a thoracotomy and without puncturing the aorta, pulmonary artery, or heart itself. The venting catheter (602) is configured to be introduced into a peripheral vein and intra-luminal advanced through the right side of the heart and into the pulmonary artery. The venting catheter includes a lumen (610) configured to withdraw blood at a rate of at least about 50 ml/min at a pressure of no less than about -350 mmHg. A flow directing means (615) is provided to facilitate guiding the catheter into the pulmonary artery by being carried by blood flow through the heart. The cardiac venting system may include, in addition to the cardiac venting catheter, a cardiopulmonary bypass system to maintain circulation of oxygenated blood, and means for arresting the patient's heart.

    Abstract: This invention is a system for inducing cardio-plegia arrest and performing an endovascular procedure within the heart or blood vessels of a patient. An endo-aortic partitioning catheter (10) has an inflatable balloon (11) which occludes the ascending aorta (12) when inflated. Cardio-plegia fluid may be infused through a lumen of the endo-aortic partitioning catheter (39) to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass. One or more endovascular devices (500) are introduced through an internal lumen (40) of the endo-aortic partitioning catheter (30) to perform a diagnostic or therapeutic endovascular procedure within the heart or blood vessels of the patient. Surgical procedures such as coronary artery bypass surgery or heart valve replacement may be performed in conjunction with the endovascular procedure while the heart is stopped. Embodiments of the system are described for performing, e.g., fiberoptic angioscopy of structures within the heart and its blood vessels, and valvuloplasty for correction of valvular stenosis.
