An interspinous process spacer and method of implanting same is provided for maintaining separation between adjacent spinous processes of adjacent vertebrae. The spacer has two lateral portions and a medial portion therebetween, the medial portion adapted to reside between the adjacent superior and inferior spinous processes in the deployed configuration and the lateral portions each comprise a superior lateral portion and an inferior lateral portion adapted to reside on the lateral side of the respective superior and inferior spinous process in the deployed configuration to maintain positioning of the interspinous process spacer between the two adjacent vertebrae. The lateral portions each comprise an expandable lateral member.

Expandable interspinous process spacer with lateral support and method for implantation

A spacer for maintaining separation between adjacent spinous processes having a first and second end support, a connecting member, and a central member positioned between the first and second end supports. The spacer is adjustable between a collapsed configuration and an expanded configuration such that when the connection member is pulled to bring the first and second end supports closer together, the central member expands into the expanded configuration to contact and support adjacent spinous processes.
