1. A fixation system for engaging tissue of a patient comprising:
an implantable fixation device comprising:
a first arm and a second arm,
a first proximal element moveable relative to the first arm between a first position and a second position,
a second proximal element moveable relative to the second arm between a first position and a second position, and
a coupling member; and
a delivery device comprising:
a catheter having a proximal end portion and a distal end portion, the catheter defining at least one lumen extending between the proximal end portion and the distal end portion,
a shaft extending through the at least one lumen and releasably coupled to the coupling member, the shaft having a lumen and a first opening intersecting the lumen,
an actuator rod moveably disposed within the lumen of the shaft such that when the actuator rod is in a first position, the actuator rod at least partially occludes the first opening, and when the actuator rod is in a second position, the first opening of the shaft is unobstructed by the actuator rod, and
a first proximal element actuator extending through the at least one lumen of the catheter, the first proximal element actuator having a first end portion, a second end portion, and an intermediate portion between the first end portion and the second end portion, the first proximal element actuator coupled to the first proximal element at the intermediate portion of the first proximal element actuator and actuatable to move the first proximal element between the first position and the second position;
wherein the second end portion of the first proximal element actuator is coupled to the shaft, and further wherein the second end portion of the first proximal element actuator comprises a first catch element configured to be received within the first opening in the shaft when the actuator rod is in the second position and to directly engage the actuator rod when the actuator rod is in the first position so as to prevent the second end portion of the first proximal element from being removed from the first opening in the shaft.
