Method and device for treating dysfunctional cardiac tissue

A method for reducing a volume of a heart, the method comprising:

• cutting a subxiphoid incision to create an opening to access the ventricles of the heart;
• inserting a curved hollow tube through a left ventricle wall into the left ventricle, through a septum, through the right ventricle, and through a right ventricle wall so that a curved lumen of the hollow tube extends from outside the heart through the left ventricle wall, then curves through the septum and right ventricle wall, and opens back outside of the heart;
• 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, the septum, and the right ventricle wall to the outside of the heart;
• securing the anchor against an outer surface of the right ventricle wall 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 outer left ventricle wall so that a volume of the left ventricle of the heart is reduced.

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 path 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 using the hollow tube by advancing the anchor along the curved path from outside the heart, through the left ventricle wall and the septum, and into the right ventricle;
• removing the hollow tube;
• 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.
