Abstract

Disclosed is a conduit that provides a bypass around a stenosis or occlusion in a coronary artery. The conduit is adapted to be positioned in the myocardium to provide a passage for blood to flow from a heart chamber to a coronary artery, at a site distal to the blockage or stenosis in the coronary artery. The conduit has a one-way valve positioned therein to prevent the backflow of blood from the coronary artery into the heart chamber.
