Abstract

Medical devices, systems, and methods reduce the distance between two locations in tissue in a minimally invasive manner, often for treatment of congestive heart failure. In one embodiment, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular 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 an epicardial surface of the heart. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter. Delivering the anchor over the guidewire may provide improved control in the delivery and placement of the anchor within the right ventricle.
