Abstract
A coronary-bypass method uses a collapsible stent made of a biocompatible material and having an inherent spring bias tending to form the stent into a substantially tubular opened configuration. The stent is disposed in a wall of a patient's heart so that the stent extends between the left ventricle of the heart and a coronary artery. Upon placement, the stent opens and allows blood to flow from the left ventricle into the coronary artery during diastole and is closed by heart contraction during systole.
