  • Publication number: 20190254825
    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: 20180318084
    Abstract: Apparatus and methods to reduce ventricular volume are disclosed. The device takes the form of a transventricular anchor, which presses a portion of the ventricular wall inward, thereby reducing the available volume of the ventricle. The anchor is deployed using a curved introducer that may be inserted into one ventricle, through the septum and into the opposite ventricle. Barbs or protrusions along the anchor body combined with a mechanical stop and a sealing member hold the device in place once deployed.

  • Publication number: 20180193148
    Abstract: Devices, systems, and methods for treating a heart of a patient may make use of structures which limit a size of a chamber of the heart, such as by deploying one or more tensile member to bring a wall of the heart and a septum of the heart into contact. A plurality of tension members may help exclude scar tissue and provide a more effective remaining ventricle chamber. The implant may be deployed during beating of the heart, often in a minimally invasive or less-invasive manner. Trauma to the tissues of the heart may be inhibited by selectively approximating tissues while a pressure within the heart is temporarily reduced. Three-dimensional implant locating devices and systems facilitate beneficial heart chamber volumetric shape remodeling.

  • Publication number: 20170165070
    Abstract: A method for reducing left ventricular volume, which comprises identifying infracted 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.
