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.

Valve designs for left ventricular conduits

A stent suitable for implantation in myocardial tissue to enhance perfusion therein may include a tubular member having first and second ends and a lumen. The first end of the stent may be configured to pierce myocardial tissue and the lumen may be configured to be placed in flow communication with a coronary vessel. The stent may further include a means for retaining the tubular member within the myocardial tissue. A method for implanting the stent may include positioning the first end of the stent at a desired implantation site and applying force to the second end of the stent to implant the stent within the myocardial tissue. The method may further include engaging the means for retaining with the myocardial tissue to retain the stent in position.
