Abstract:
1. An implant device for implantation between spinous processes of adjacent vertebrae, the implant device comprising: an implant body for being inserted between spinous processes of adjacent vertebrae; the body comprising a first member having generally opposite first and second end portions and a seat portion therebetween, wherein the seat portion is configured to engage a spinous process of a vertebra, wherein an arm of the first member extends from the first end portion of the first member; a tool engagement portion of the first member at the second end portion of the first member; a second member having generally opposite first and second end portions and a seat portion therebetween, wherein the seat portion is configured to engage a spinous process of an adjacent vertebra, wherein an arm of the second member extends from the first end portion of the second member; a tool engagement portion of the second member at the second end portion of the second member; and an adjustable connection at the first end portions of the first and second members allowing the implant body to be engaged with a tool at the tool engagement portions at the second end portions of the first and second members and shifted between a compact orientation, wherein the arm of the first member is engaged with the arm of the second member, and an extended orientation, wherein the arms of the first and second members are shifted to extend away from each other, wherein the second end portions, including the respective tool engagement portions thereof, of each of the first and second members is enlarged relative to the corresponding seat portions so that the arms at the first end portions, the intermediate seat portions, and the enlarged second end portions cooperate to form a generally U-shaped saddle configuration for each of the first and second members, and the implant body is configured to be inserted between the spinous processes along a lateral direction of insertion, wherein the seat portions each face the lateral direction in the compact orientation and wherein when the first and second arms are shifted to extend away from each other, the first and second seat portions face opposite one another in respective upward and downward directions generally orthogonal to the lateral direction of insertion.
