  • Publication number: 20130324787
    Abstract: A method for reducing left ventricular volume, which comprises identifying infarcted tissue during open chest surgery; reducing left ventricle volume while preserving the ventricular apex; and realigning the ventricular apex, such that the realigning step comprises closing the lower or apical portion of said ventricle to achieve appropriate functional contractile geometry of said ventricle in a dyskinetic ventricle of a heart.

  • Patent number: 8506474
    Abstract: Various methods and devices are provided for reducing the volume of the ventricles of the heart. In one embodiment, a method for reducing the ventricular volume of a heart chamber is provided including the steps of inserting an anchoring mechanism onto dysfunctional cardiac tissue, deploying one or more anchors into the dysfunctional cardiac tissue, raising the dysfunctional cardiac tissue using the anchors, and securing the anchors to hold the dysfunctional cardiac tissue in place. Further, a device for reducing the volume of the ventricles of a heart chamber is provided where the device has one or more clips for placement on dysfunctional cardiac tissue of a heart, one or more anchors for deployment and securement into the dysfunctional cardiac tissue, and a lifting mechanism for raising the one or more anchors and the dysfunctional cardiac tissue.

  • Patent number: 8491455
    Abstract: Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.

  • Publication number: 20130096579
    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.

  • Publication number: 20130090684
    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.

  • Publication number: 20130090523
    Abstract: Embodiments described herein provide devices, systems, and methods that reduce the distance between two locations in tissue, often for treatment of congestive heart failure. For example, 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. The anchor may be deployed into the heart through a working lumen of a minimally invasive access tool. The minimally invasive access tool may have a plurality of grippers near a distal end of the working lumen. The grippers may engage epicardial tissue of the heart and may be moved radially inwardly relative so as to provide stabilization of the epicardial tissue and/or hemostasis near an access site where the anchor is inserted through the epicardium. The minimally invasive access tool may minimize blood loss from the access site and improve anchor implant processes.

The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a catheter. An anchor force may be applied within a desired range to secure the anchors about the septum and epicardial surface. The anchor force may inhibit migration of the anchors relative to the septum and epicardial surface.

  • Patent number: 8394008
    Abstract: Devices, systems, and methods for treating a heart of a patient may make use of one or more implant structures which limit a size of a chamber of the heart, such as by deploying a tensile member to bring a wall of the heart toward (optionally into contact with) a septum of the heart.
