1. An aortic closure device, comprising:
a deployment assembly configured to be inserted in a puncture in an aorta;
a tamper carried by the deployment assembly, the tamper having:
a tamper channel that extends therethrough,
an outer surface,
at least one first cut at a distal end of the tamper and that extends from the outer surface toward the tamper channel, and
at least one second cut at the distal end of the tamper opposite the first cut and that extends from the outer surface toward the tamper channel, wherein the at least one first cut and the least one second cut are configured to permit the distal end of the tamper to flex;
a sealing element captured by the deployment assembly;
a suture assembly that extends through the tamper channel such that the tamper is movable along the suture assembly, the suture assembly being releasably coupled to the sealing element; and
an actuator coupled to the deployment assembly, the actuator having a) a first actuation phase that causes the deployment assembly to release the sealing element therefrom while remaining coupled to the suture assembly, b) a second actuation phase that causes the tamper to move in a distal direction toward contact with the sealing element, and c) a third actuation phase that causes the tamper to move in a proximal direction that is opposite the distal direction to release the suture assembly from the sealing element.
