1. An implant delivery device comprising:
an outer housing having a longitudinal axis;
a dampener assembly that controls implantation speed, where the dampener assembly comprises a dampener housing axially fixed relative to the outer housing, where the dampener housing comprises a vent having a predetermined configuration;
a shuttle assembly having an activated state and a fired state, where the shuttle assembly comprises a shuttle slidably positioned within the outer housing and having a first position, a second position and a third position;
a pusher wire axially and rotationally fixed to the shuttle at a proximal end such that a distal end of the pusher wire protrudes away from the shuttle along the longitudinal axis in a distal direction; and
a needle assembly,
wherein the predetermined configuration of the vent directly controls the implantation speed;
wherein the shuttle comprises a first latch surface defining a first angle that is less than 90 degrees when measured relative to the longitudinal axis, wherein the first latch surface is slidably engaged with a second latch surface on an activation member; and
wherein a downward pivoting movement of the activation member causes the sliding movement of the shuttle from the first position to the second position in a proximal direction, and once the second latch surface disengages from the first latch surface, the shuttle moves from the second position to the third position in a distal direction such that the third position is located distally of the first position.
