摘要：
A transvenously deployed myocardial restraint device provides mechanical restraint of a dilated left ventricle and improves heart function. The device includes a delivery wire with a restraining coil that is straightened for percutaneous delivery to the heart and recoiled once positioned in a pericardial space adjacent a ventricular heart wall. Alternatively, a balloon on the end of the delivery wire is delivered similarly to the coil and is then inflated in the pericardial space to restrain the dilated portion of the left ventricle. A trailing end of the coil forms a tether that is anchored to the left ventricular free wall and to the ventricular septum by an intraventricular septal anchor and connected by the tether through the ventricular septum using the same delivery system.
