Abstract
A catheter with a tissue property sensor provides for localization of myocardial infarction (MI) by utilizing one or more differences between properties of infarcted myocardial tissue and properties of normal myocardial tissue. The tissue property sensor is to be placed on endocardial wall or epicardial wall during catheterization to sense at least one tissue property allowing for detection of MI. In one embodiment, the tissue property sensor includes a contractility sensor and senses a tissue property in various locations on endocardial wall or epicardial wall and detects substantial changes in the tissue property that indicate a boundary between infarcted tissue and normal tissue.
