A conduit is provided to provide a bypass around a blockage in the coronary artery.
The conduit is adapted to be positioned in the myocardium or heart wall to provide
a passage for blood to flow between a chamber of the heart such as the left ventricle
and the coronary artery, distal to the blockage. The stent is self-expanding or
uses a balloon to expand the stent in the heart wall. Various attachment means
are provided to anchor the stent and prevent its migration.
