摘要： A method and device that addresses the problem of an incompetent aortic valve by using a simple cardioplegia catheter that can deliver cardioplegia solution to the coronary arteries through the usual aortic cannulation site even in the presence of aortic valve incompetence. The device includes a cardioplegia cannula (32) with an additional lumen containing a nitinol wire (34) inside it that allows advancement of a folded nitinol umbrella (36) with a non-porous membrane or a compressed nitinol ring that covers the aortic valve when opened. During installation, after puncture of the aorta by the coaxial needle and removal of the coaxial needle but before installation of the cardioplegia solution through the central lumen of the catheter, the nitinol umbrella (in folded position) or nitinol ring (in compressed position) is advanced through the second lumen into the aorta just above the aortic valve. The nitinol umbrella is unfolded using the nitinol wire to expose the inverted umbrella configuration with attached membrane and is then advanced as a unit with the cardioplegia catheter until the nitinol umbrella covers the aortic valve at its deployed position.

摘要： A percutaneously inserted bistable heart valve prosthesis is folded inside a catheter for transseptal delivery to the patient's heart for implantation. The heart valve has an annular ring, a body member having a plurality of legs, each leg connecting at one end to the annular ring, claws that are adjustable from a first position to a second position by application of external force so as to allow ingress of surrounding heart tissue into the claws in the second position, and leaflet membranes connected to the annular ring, the body member and/or the legs, the leaflet membranes having a first position for blocking blood flow therethrough and a second position for allowing blood flow therethrough. The heart valve is designed such that upon removal of the external force the claws elastically revert to the first position so as to grip the heart tissue positioned within the claws, thereby holding the heart valve in place. The body member and claws may be integrated into a one-piece design. The heart valve may be used as a prosthesis for the mitral valve, aortic valve, pulmonary valve, or tricuspid valve by adapting the annular ring to fit in a respective mitral, aortic, pulmonary, or tricuspid valve opening of the heart.
