Trans-catheter ventricular reconstruction structures, methods, and systems for treatment of congestive heart failure and other conditions
First Claim
1. A method for treating a heart within a patient, the heart having first and second chambers with a septum therebetween, the second chamber having an exterior wall, the method comprising:
- advancing a first elongate shaft from outside the patient into the heart along a first path so that a distal end of the first shaft is disposed in the first chamber;
advancing a second elongate shaft along a second path from outside the heart, through the exterior wall and through the septum so that a distal end of the second shaft is disposed in the first chamber;
joining the first path to the second path by coupling the distal end of the first shaft with the distal end of the second shaft within the first chamber of the heart;
advancing a first anchor and an elongate tension member into the heart along the joined paths, wherein the tension member is advanced into the first chamber and the tension member extends from the first anchor in the first chamber, through the septum, through the second chamber, and through the exterior wall with an end portion of the tension member being disposed outside the heart;
coupling a second anchor to the tension member end portion outside the heart; and
applying tension between the anchors with the tension member so that the anchors urge the septum and the external wall to engage.

Abstract
Embodiments described herein include devices, systems, and methods for reducing the distance between two locations in tissue. In one embodiment, an anchor may reside within the right ventricle in engagement with the septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along a surface of the heart. Perforating the exterior wall and the septum from an epicardial approach can provide control over the reshaping of the ventricular chamber. Guiding deployment of the implant from along the epicardial access path and another access path into and through the right ventricle provides control over the movement of the anchor within the ventricle. The joined epicardial pathway and right atrial pathway allows the tension member to be advanced into the heart through the right atrium and pulled into engagement along the epicardial access path.

21. A method for treating a heart within a patient having congestive heart failure, the heart having first and second chambers with a septum therebetween, the second chamber having an exterior wall, the method comprising:
-
advancing a first elongate shaft from outside the patient into the heart along a first path so that a distal end of the first shaft is disposed in the first chamber; forming a second path by advancing a second elongate shaft from outside the heart, through the exterior wall and through the septum so that a distal end of the second shaft is disposed in the second chamber; coupling the distal end of the first elongate shaft with the distal end of the second elongate shaft within the second chamber of the heart so as to join the first path to the second path; advancing a tension member and a first anchor of an implant distally into the first chamber of the heart along the first path, wherein the tension member is advanced distally from the chamber by pulling a distal end of the tension member along the second path so that the tension member extends from the first anchor in the first chamber, through the septum, through the second chamber, and through the exterior wall to the distal end of the tension member outside the heart; coupling a second anchor to the tension member outside the heart; and applying tension between the anchors with the tension member so that the septum engages the wall such that the congestive heart failure is mitigated.

22. A method for treating a heart within a patient having congestive heart failure, the heart having first and second chambers with a septum therebetween, the second chamber having an exterior wall, the method comprising:
-
advancing a first elongate shaft from outside the patient into the heart along a first path so that a distal end of the first shaft is disposed in the first chamber; forming a second path by advancing a second elongate shaft from outside the heart, through the exterior wall and through the septum so that a distal end of the second shaft is disposed in the second chamber; coupling the distal end of the first elongate shaft with the distal end of the second elongate shaft within the second chamber of the heart so as to join the first path to the second path; advancing a first anchor distally into the first chamber of the heart along the second path and within the first chamber along the first path, wherein the tension member trails proximally from the anchor as the anchor is advanced distally so as to extend from the first anchor in the first chamber, through the septum, through the second chamber, and through the exterior wall to a proximal end of the tension member disposed outside the heart; coupling a second anchor to the tension member outside the heart; and applying tension between the anchors with the tension member so that the septum engages the wall.
