an inner handle including a loading chamber configured to receive a nasal implant;
an outer handle configured to move axially relative to the inner handle;
a needle extending distally from the inner handle, the needle having a central lumen and a distal opening; and
a push rod configured to move the nasal implant from the loading chamber, through the central lumen, and out the distal opening of the needle, wherein the push rod is coupled to the outer handle such that the push rod moves axially relative to the inner handle when the outer handle is moved axially relative to the inner handle,
wherein the outer handle is configured to sheath the inner handle,
wherein the outer handle is configured to move distally relative to the inner handle to cover the loading chamber, and
wherein the outer handle is configured to move proximally relative to the inner handle to expose the loading chamber for receiving the nasal implant.
