  • Publication number: 20200229806
    Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.

  • Patent number: 10653427
    Abstract: System for fixation of leaflets of a heart valve including an implantable fixation device including a first distal element and a second distal element, a first proximal element moveable relative to the first distal element between a first position and a second position, and a second proximal element moveable relative to the second distal element between a first position and a second position. The system further includes a delivery device including a catheter having a proximal end portion and a distal end portion, the implantable fixation device releasably coupled to the distal end portion of the catheter, the catheter defining at least one lumen extending between the proximal end portion and the distal end portion.
