Claim 15:
16. A nasal implant delivery tool comprising:
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 between a plurality of locking positions;
a plurality of locking structures configured to releasably lock the outer handle from moving relative to the inner handle at the plurality of locking positions;
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 move distally relative to the inner handle to cause the push rod to move the nasal implant from the loading chamber, through the central lumen, and out the distal opening of the needle,
wherein the outer handle is configured to move proximally relative to the inner handle to expose the loading chamber for receiving the nasal implant, and
wherein the plurality of locking positions include:
a primed locking position where the plurality of locking structures lock the outer handle from moving distally relative to the inner handle and causing the push rod to move the nasal implant out the distal opening of the needle, and
a pre-loaded locking position where the plurality of locking structures lock the outer handle from moving proximally relative to the inner handle to expose the loading chamber for receiving the nasal implant,

a first button on the outer handle configured to disengage the plurality of locking structures to allow the outer handle to move distally relative to the inner handle and cause the push rod to move the nasal implant out the distal opening of the needle; and
a second button on the outer handle configured to disengage the plurality of locking structures to allow the outer handle to move proximally relative to the inner handle to expose the loading chamber for receiving the nasal implant.
