  • Patent number: 6641610
    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.

  • Publication number: 20030055371
    Abstract: Left ventricular conduits and related methods are disclosed for achieving bypass of a partially or completely occluded coronary artery. More broadly, conduits for allowing communication of bodily fluids from one portion of a patient's body to another and related methods are disclosed, including conduits for forming a blood flow path from a chamber of the heart to a vessel or from one vessel to another. In other embodiments, the conduits achieve a coronary artery bypass by allowing blood communication between the left ventricle and the coronary artery or between a proximal portion of the coronary artery and a distal portion of the coronary artery. The conduits may be placed completely through the heart wall or extend only partially therein. Conduits may take on a variety of configurations for allowing the control of blood flow therethrough, including curved or tapered shapes.
