Abstract
A blood flow path is formed from a heart chamber to a coronary vessel. The coronary vessel has a predetermined diameter. A hollow conduit is selected having a vessel portion and a myocardial portion. The vessel portion has an open leading end sized to be inserted into the coronary vessel. The myocardial portion has an open leading end and the myocardium portion is sized to extend through a thickness of the heart wall. The conduit is selected with the vessel portion sized to be inserted within the vessel without dilating the vessel to such a degree that the vessel is incapable of further dilation in response to blood flow in the vessel. The myocardial portion is placed in the heart wall with the open leading end of the myocardial portion protruding into the heart chamber. The leading end of the vessel portion is placed in the coronary vessel. The vessel is secured to the vessel portion by urging the vessel against the vessel portion at a point of attachment spaced from the open leading end of the vessel portion.
