Abstract
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.
Claims21
A method for reducing left ventricular volume in a congestive heart failure heart, the method comprising the steps of:
- a. identifying infarcted tissue during open chest surgery;
- b. reducing left ventricle volume while preserving the ventricular apex;
- and
- c. realigning the ventricular apex;
- wherein said realigning step comprises closing of a lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle.
A method for performing minimally invasive left ventricular volume reduction in a congestive heart failure heart, the method comprising the steps of:
- a. perforating the septum of the heart by inserting a catheter through a right ventricle;
- b. identifying infarcted tissue on the septum;
- c. advancing the catheter through the infarcted tissue of the septum;
- d. identifying infracted tissue on the left ventricular wall;
- and
- e. bringing together the infracted tissue closer to each other and thereby minimizing the volume of the left ventricle.
A system for resizing a left ventricle of a heart, comprising:
- a. a catheter inserted into the left ventricle via a puncture in the septum of the heart;
- b. a first fixation member positioned on an external surface wall of said left ventricle;
- c. a second fixation member positioned on a surface of said septum external of said left ventricle,
- wherein said catheter connects said first and second fixation members and wherein tension applied on said catheter causes said second fixation member to pull said external surface wall of said left ventricle towards said septum to close off a lower or apical portion of said left ventricle.
