  • Patent number: 8728026
    Abstract: Devices and methods for their use in increasing the aortic valve flow of a stenotic aortic valve are provided. The subject devices include an aortic valve isolation element and an aortic valve flushing element. The aortic valve isolation element is made up of a ventricular side aortic valve occlusion element, coronary ostia occlusion elements and an ascending aorta occlusion element. The aortic valve flushing element is made up of a dissolution fluid introducing element and a fluid removal element. In practicing the subject methods, a stenotic aortic valve is first isolated. Next, the isolated valve is flushed with a dissolution fluid, e.g., an acidic dissolution fluid, for a period of time sufficient for the aortic valve flow of the treated valve to be increased. In certain embodiments, the valve is also contacted with a dissolution fluid attenuating fluid, e.g., a buffer, during the flushing step in order to limit the contact of non-valve tissue with the dissolution fluid.
