  • Patent number: 11793643
    Abstract: Apparatus and methods to reduce ventricular volume are disclosed. The device takes the form of a transventricular anchor assembly, which presses a portion of the ventricular wall inward, thereby reducing the available volume of the ventricle. The anchor assembly 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 a tension member of the anchor assembly combined with a mechanical stop and a sealing member hold the device in place once deployed.

  • Patent number: 11744615
    Abstract: A method for performing a therapeutic intervention in a pericardial space of a heart includes delivering a catheter into a right atrium of the heart and steering the catheter so that a distal end of the catheter is positioned adjacent an access site in the right atrium. The distal end of the catheter is anchored in a heart wall of the right atrium adjacent the access site and the heart wall is inverted to separate an exterior surface of the inverted heart wall from contact with parietal pericardial tissue. The inverted heart wall is penetrated to provide access to the pericardial space around the heart. A device is delivered through the penetrating in the inverted heart wall to perform the therapeutic intervention in the pericardial space.

  • Patent number: 11540822
    Abstract: A heart tissue gripping device may include a body portion, an elongate shaft, and a tissue gripping member that is attached to the distal end of the elongate shaft. The tissue gripping member being may be positioned adjacent a heart surface by insertion through an incision in the body. The tissue gripping member may releasably attach to tissue of the heart surface to facilitate a surgical instrument in performing one or more procedures. A coupling of the tissue gripping member may releasably attach the surgical device to the tissue gripping member to allow the device to access the tissue of the heart surface.

  • Patent number: 11419723
    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.

  • Patent number: 11399942
    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.

  • Patent number: 11273040
    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.

  • Publication number: 20200289268
    Abstract: According to one embodiment, a heart anchor tensioning device includes a main body and an elongate shaft. A tension member or tether may be inserted through a lumen of the elongate shaft to allow the shaft to be advanced over the tension member and within a body while the main body is positioned outside of the body. The device also includes an anchor coupling mechanism that is configured to engage a heart anchor and move the heart anchor into engagement with a first wall of the heart. The anchor coupling mechanism is able to lock the heart anchor to inhibit proximal movement of the heart anchor along the tension member. The device further includes a tension indicating mechanism that provides an indication of a force being applied to the heart anchor by the device.
