US 2016/0095600 A1 · OVER-THE-WIRE CARDIAC IMPLANT DELIVERY SYSTEM FOR TREATMENT OF CHF AND OTHER CONDITIONS

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.

Dependent claims

1-28. (canceled)

A system for treating a heart of a patient comprising:

a guidewire insertable through a wall of the heart into a chamber of the heart;
a delivery catheter having a first end, a second end, and a lumen extending between the first end and the second end, the delivery catheter being insertable over the guidewire through the wall;
an anchor comprising a lumen configured to receive the guidewire so that the anchor is insertable over the guidewire through the wall via the delivery catheter;
and
a tension member coupled with the anchor to urge the wall against a second wall.
