  • Patent number: 12653673
    Abstract: The present disclosure relates to repair devices for repair of regurgitant mitral valves. A repair device includes a body having a perimeter defining an upper side and a lower side. An annular groove is disposed along a posterior section of the perimeter of the device and is configured to receive posterior rim tissue of a mitral valve annulus. First and second anchors extend from the body in an anterior direction. The first and second anchors are configured to engage with respective commissures of the mitral valve to assist in securing the repair device in position. The repair device is structured to minimize or eliminate imparting or transmitting radially outward forces along an anterior section so as to avoid imparting forces to the septum to avoid hindering the function of the aortic valve and the left ventricular outflow tract.

  • Patent number: 12642586
    Abstract: A transapical removal device that can be deployed in a catheter procedure to capture for removal or alteration a mitral valve clip or heart tissue, such as the anterior leaflet of the mitral valve, and methods of use are disclosed. The removal device includes a delivery catheter configured to be deployed near a mitral valve using a guide catheter. The delivery catheter has a snare head at the distal end, which assumes a collapsed state during movement of the delivery catheter through the guide catheter and deployed state for capturing a mitral valve clip or anterior leaflet. The snare head has one or more ablation delivery catheters configured to ablate tissue surrounding the pre-positioned mitral valve clip or anterior leaflet. In some arrangements within the scope of the present disclosure, the removal device includes a deployment mechanism for deploying a new transcatheter valve into the mitral valve.

  • Patent number: 12582522
    Abstract: A mitral valve clip includes a stud, a lock, and two arms. The stud includes a shank, and the lock includes a frame relative to which the stud is translatable and into which the shank extends. The lock is able to prevent movement of the stud relative to the lock in at least one direction by locking engagement of the shank. The two arms are connected to the lock and the stud such that an angle between the arms depends on a location of the stud relative to the lock. The locking engagement of the shank that prevents movement of the stud relative to the lock in the at least one direction is only possible when the angle between the arms is below a predefined locking threshold.

  • Publication number: 20250375296
    Abstract: An implantable fixation device includes fixation elements and gripping elements for fixating tissue. A stud is coupled to the fixation elements and is configured such that movement of the stud moves the fixation elements within a range of positions. A binding plate is configured to engage the stud to arrest its movement and to disengage the stud to allow its movement. A biasing element engages the binding plate and biases the binding plate into engagement with the stud. A harness with a single foot is engaged to the binding plate is configured such that tensioning the harness moves the binding plate in opposition to the bias of the biasing element so as to release the binding plate from the stud. Releasing tension on the harness returns the binding plate into engagement with the stud and secures the fixation elements in one position within the range of positions.
