Lateral spinous process spacer with deployable wings

An implant for positioning between adjacent spinous processes comprising:

• an elongate body having a longitudinal axis, the elongate body including a leading end portion and a trailing end portion, wherein the trailing end portion includes a flange configured and dimensioned to contact at least one of the adjacent spinous processes;
• one or more tabs attached to the leading end portion;
• and
• a gear barrel insert extending through the trailing end portion, wherein the one or more tabs are actuatable by the rotatable gear barrel insert such that when the gear barrel insert is rotated, the tabs extend outwardly from the leading end portion.

An implant for positioning between adjacent spinous processes comprising:

• an elongate body having a longitudinal axis, the elongate body including a leading end portion, a trailing end portion, and a central support portion disposed between the leading and trailing end portions, wherein the trailing end portion extends from a proximal end to a distal end, and the trailing end portion includes a flange proximate to the distal end;
• one or more tabs attached to the leading end portion;
• and
• a gear barrel insert extending through the trailing end portion, wherein the one or more tabs are actuatable by the rotatable gear barrel insert such that when the gear barrel insert is rotated, the tabs extend outwardly from the leading end portion,
• wherein the one or more tabs have a first position where the one or more tabs are generally recessed within the leading end portion and the implant is configured to facilitate lateral insertion between the adjacent spinous processes,
• wherein the one or more tabs have a second position where the one or more tabs extend outwardly, and the adjacent spinous processes are maintained between the one or more tabs of the leading end portion and the flange of the trailing end portion, thereby limiting movement of the implant along the longitudinal axis.
