摘要：
Systems and methods are disclosed for reinforcing ischemic tissue of a heart. A reinforcing element is initially positioned within a lumen of a delivery needle. The delivery needle is urged into the ischemic tissue and the reinforcing element is urged out of the needle into the ischemic tissue. The reinforcing element may be embodied as a coiled, undulating, or arcuate spring and may include a shape-memory material. A bioabsorbable material may maintain the reinforcing element in a deformed state. The reinforcing element may be tensioned as it is positioned within the myocardium in order to provide a cinching force by means of a cord lock selectively releasing the reinforcing element. The reinforcing element may be embodied as a number of spiral portions secured to a hub and urged outwardly by rotation of the hub.
