1. A ligating device comprising:
a capsule having an interior;
a clamp assembly including a plurality of clamps, each clamp including a first arm having a first free end and a second arm having a second free end, wherein the clamp assembly includes a compacted state in which the plurality of clamps are compressed within the capsule and a deployed state in which at least the free ends of the plurality of clamps are positioned outside of the interior of the capsule, wherein the first free end is closer to the second free end in the compacted state as compared to the deployed state;
a push rod releasably secured to the clamp assembly, wherein the push rod is configured to move the clamp assembly relative to the capsule; and
a delivery rod releasably secured to the capsule, wherein the delivery rod is configured to move the capsule relative to the clamp assembly,
wherein the capsule includes an open proximal end such that the clamp assembly transitions from the compacted state to the deployed state by deploying out of the open proximal end, and wherein the push rod and the delivery rod extend proximally through the open proximal end.
