Tissue grasping devices and related methods

A tissue fixation kit, the kit comprising:

• a delivery catheter;
• and
• a tissue fixation system couplable to the delivery catheter at a distal end of the delivery catheter, the tissue fixation system configured for intravascular delivery and for heart valve tissue treatment, wherein the tissue fixation system includes:
• a center portion defining a longitudinal axis,
• a distal element pivotally moveable relative the longitudinal axis, and
• a gripper formed of a shape-memory material, wherein at least a portion of the gripper is configured to move relative to the distal element to capture native valve leaflet tissue therebetween, wherein the gripper includes:
• a bend configured to flex to allow the gripper to move relative to the distal element,
• a furcated section having an opening defined therein, the opening including:
• a first end portion having a first maximum cross-dimension defined at a widest location within the first end portion, and
• a second end portion having a second maximum cross-dimension defined at a widest location within the second end portion,
• wherein the first maximum cross-dimension is different than the second maximum cross-dimension.
