  • Publication number: 20210169651
    Abstract: A valve fixation device may comprise a unitary elongate member that is biased towards a closed configuration wherein at least a pair of tissue engaging surfaces of the elongate member are held adjacent to each other by a bias force. The bias force is at least equal to a valve leaflet grasping force, enabling the fixation device to grasp and retain leaflets as part of cardiac treatment. A delivery tool including a spreader may independently translate the tissue engaging surfaces to enable cardiac leaflets to be captured and retained by and/or between the tissue engaging surfaces. The valve fixation device may include at least two arms, each of which may be independently controlled to grasp and capture opposing leaflets of a valve, such as the anterior and posterior leaflets of a mitral valve, to reduce the size of the valve opening and improve cardiac performance.
