1. A fixation device for engaging tissue comprising:
a pair of fixation elements, each fixation element having a first end and a second end opposite the first end, the first ends being moveable between a closed position and an open position;
a pair of gripping elements, each gripping element moveable with a respective fixation element and disposed in opposition to at least a portion of the respective fixation element to capture tissue therebetween; and
a central portion operatively connected to each gripping element at a respective central portion-gripping element interface, the central portion having a distal end, the central portion having a width “W1” proximate the distal end and extending in a direction toward each gripping element, each gripping element being cantilevered to the central portion at its respective central portion-gripping element interface and having a free end opposite its respective central portion-gripping element interface and a length “L1” defined between the respective central portion-gripping element interface and the free end, wherein a ratio of the length to the width L1:W1 is about 3.18:1,
wherein the central portion at least partially defines a gap extending between each gripping element and its respective fixation element and also extending along the length L1 of each gripping element between the free end thereof and the central portion, the gap being configured to receive tissue of a native valve leaflet.
 
11. A fixation device for engaging tissue comprising:
a pair of fixation elements, each fixation element having a first end and a second end opposite the first end, the first ends being moveable between a closed position and an open position;
a pair of gripping elements, each gripping element moveable with a respective fixation element and disposed in opposition to at least a portion of the respective fixation element to capture tissue therebetween; and
a central portion operatively connected to each gripping element at a respective central portion-gripping element interface, the central portion having a distal end defining a reference plane perpendicular to a central axis of the central portion, the central portion having a width “W1” proximate the distal end, each gripping element being cantilevered to the central portion at its respective central portion-gripping element interface and having a free end opposite its respective central portion-gripping element interface and a length “L1” defined between the respective central portion-gripping element interface and the free end, wherein a height “H1” is defined by a vertical dimension between the reference plane and the central portion-gripping element interfaces, and a ratio of the length to the height L1:H1 is about 1.85:1,
wherein the central portion at least partially defines a gap extending between each gripping element and its fixation element and also extending along the length L1 of each gripping element between the free end thereof and the central portion, the gap being configured to receive tissue of a native valve leaflet.
