Tissue Fixation Device With Improved Tissue Securement

A fixation device comprising:

• a first proximal element having a first end portion, a second end portion, a gridded frame disposed between the first end portion and the second end portion, and a plurality of frictional elements, the gridded frame having a plurality of axial struts and a plurality of transverse struts intersecting the axial struts to define a plurality of openings extending through the first proximal element, and at least some of the frictional elements extending from at least some of the transverse struts, the first proximal element defining a longitudinal axis extending between the first end portion and the second end portion thereof, and the first proximal element being bent in a transverse plane which extends in a direction transverse to the longitudinal axis;
• and
• a first distal element disposed in opposition to the first proximal element and having a first end portion, a second end portion, and a cavity disposed between the first end portion and the second end portion, the cavity being configured to at least partially receive the gridded frame of the first proximal element,
• wherein the first proximal element is moveable relative to the first distal element between a first position and a second position, and, when the first proximal element is in the second position, the gridded frame nests within the cavity of the first distal element.
