Heart failure is a significant problem, and carries substantial mortality. According to studies, left ventricular (LV) remodeling contributes independently to heart failure progression. Prevention and reversal of LV remodeling are correlated with decreased risk of death and heart failure events. IK-5001 is an implantable device to be used in subjects with recent myocardial infarction (MI). The IK-5001 device has been shown to directly halt the remodeling process that occurs following acute MI. IK-5001 replaces the damaged extracellular matrix (ECM) that has degraded during infarction, supports the damaged myocardial tissue, prevents local dyskinesis, and decreases wall stress. Because of its minimal interaction with the myocardium, its mechanism of action, its lack of specific pharmacologic activity and its elimination behavior, IK-5001 is a medical device in concurrence with the Global Harmonization Task Force's harmonized definition for medical devices.
