1. An apparatus for use in a coronary artery bypass procedure at a coronary vessel disposed lying at an exterior of a heart wall, the apparatus comprising;a hollows blood flow conduit having a first end sized for being inserted into and retained within the cart wall of a heart chamber containing oxygenated blood with said first end sized to span a thickness of the heart wall with an opening of the first end in blood-flow communication with blood contained within the chamber, said first end having sufficient radial rigidity to resist collapse of said first end in response to contraction of said heart; the conduit having a second end sized for being inserted within the coronary vessel with an opening of the second end in blood flow communication with a lumen of the coronary vessel, said second end having an open cell structure within said vessel; and the conduit defining a blood flow path between the openings of the first and second ends.
