Method and device for percutaneous left ventricular reconstruction

摘要

A method for reducing left ventricular volume, which comprises identifying infarcted tissue during open chest surgery; reducing left ventricle volume while preserving the ventricular apex; and realigning the ventricular apex, such that the realigning step comprises closing the lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle in a dyskinetic ventricle of a heart.

1. A method for reducing a chamber volume in a heart comprising:
applying suction to an epicardium of said chamber to bring opposing walls of said chamber adjacent one another and thereby reduce a size of said chamber, said opposing walls including a first wall and a second wall; and penetrating a needle across said first and second walls of said chamber with said first wall adjacent said second wall; wherein said suction is applied by engaging the epicardium with a suction device so that the epicardium is drawn into the suction device.
