Trans-catheter ventricular reconstruction structures, methods, and systems for treatment of congestive heart failure and other conditions
First Claim
1. A method for delivering an anchor to a septal wall of a patient'"'"'s heart, the anchor being coupled at a proximal end of an elongate tension member and being pivotable between an insertion configuration and a deployed configuration, the method comprising:
- inserting a catheter from outside a patient'"'"'s body into the heart so that a distal end of the catheter is disposed in a first chamber of the heart adjacent a proximal side of the septal wall;
inserting a distal end of the elongate tension member within a lumen of the catheter while the anchor is positioned proximally of and outside the patient'"'"'s body;
advancing the elongate tension member and the anchor through the lumen of the catheter with the elongate tension member advanced distally of the anchor and with the anchor in the insertion configuration, the elongate tension member being advanced through the lumen of the catheter so that the distal end of the elongate tension member is disposed within the first chamber;
advancing the distal end of the elongate tension member through a perforation in the septal wall and into a second chamber of the heart;
advancing the elongate tension member through the perforation in the septal wall until the anchor is positioned adjacent the proximal side of the septal wall;
pivoting the anchor from the insertion configuration to the deployed configuration; and
tensioning the elongate tension member to pull the anchor into contact with the proximal side of the septal wall.

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.

8. A method for delivering an anchor to a wall of a heart of a patient, the anchor being coupled at a proximal end of an elongate tension member, the method comprising:
-
coupling a distal end of the elongate tension member with a guidewire, the guidewire having opposing ends that are positioned outside the patient'"'"'s body and an elongate section that traverses through the wall of the heart and through a chamber of the heart; inserting the distal end of the elongate tension member within the patient'"'"'s body while the anchor is positioned outside of the body; advancing the elongate tension member and the anchor through the patient'"'"'s body with the elongate member positioned distally of the anchor; advancing the distal end of the elongate tension member through the wall of the heart; advancing the elongate tension member through the wall until the anchor is positioned within the chamber of the heart adjacent the wall; and tensioning the elongate tension member to pull the anchor into contact with the wall. - View Dependent Claims (9, 10, 11, 12, 13, 14)
