Transmyocardial implant with induced tissue flap

A method for forming a blood flow path from a heart chamber to a coronary vessel on an exterior surface of a heart wall, the coronary vessel having a predetermined diameter, the method comprising:

• selecting a hollow conduit having a vessel portion and a myocardial portion, the vessel portion having an open leading end sized to be inserted into the coronary vessel, the myocardial portion having an open leading end and the myocardium portion being sized to extend through a thickness of the heart wall;
• selecting said conduit with said vessel portion sized to be inserted within said vessel without dilating said vessel to such a degree that said vessel is incapable of further dilation in response to blood flow in said vessel
• placing the myocardial portion in the heart wall with the open leading end of the myocardial portion protruding into the heart chamber;
• placing the leading end of the vessel portion in the coronary vessel;
• securing said vessel to said vessel portion by urging said vessel against said vessel portion at a point of attachment spaced from said open leading end of said vessel portion.
