Patent ID: 8506474

Claim:
A method for reducing a volume of a heart, the method comprising: from a posterior approach, inserting a curved hollow tube through a posterior left ventricle wall into a left ventricle and through a septum into a right ventricle so that a curved lumen of the hollow tube extends from outside the heart and posterior of the heart, through the left ventricle wall, and then curves through the septum and opens into the right ventricle; deploying an anchor connected to a ratchet mechanism through the hollow tube by advancing the anchor within the curved lumen from outside the heart, through the left ventricle wall and the septum, and into the right ventricle; removing the hollow tube so that the ratchet mechanism extends from the deployed anchor, through the ventricle wall and the septum, and outside the patient; securing the anchor against the septum inside the right ventricle by securing a locking mechanism to the ratchet mechanism, and by advancing the locking mechanism along the ratchet mechanism toward the anchor; and locking the locking mechanism against the left ventricle wall so that a volume of the left ventricle of the heart is reduced.
