Abstract

A conduit for creating a passage from a right atrium to a left atrium, through a mitral valve into the left ventricle, and to provide a passage from the left ventricle into the aortic valve. The conduit includes an elongate tubular member having a shaft with a proximal section and a distal loop section at a distal end of the proximal section. The distal loop section includes a proximal curve, a distal curve, a generally straight segment extending between the curves, and a distal tip. The shaft in the distal loop section curves back on itself so that proximal curve is formed by a part of the shaft that is closer along the length of the shaft to the distal tip. The shapes of the proximal and distal curves are selected to direct the distal tip into the mitral valve after it has crossed the inter-atrial septum from the right atrium to the left atrium of the heart, and to orient the distal opening of the distal tip towards the aortic valve when the proximal curve is in the mitral valve and the distal tip is in the left ventricle.
