Interspinous process implants and methods of use
First Claim
1. A method, comprising:
- inserting a first implant member into a location of a body including a space between adjacent spinous processes from a first side of the adjacent spinous processes, the first implant member comprising first and second wings and a first spacer disposed between the first and second wings, the first and second wings each having a greater height than the first spacer, wherein the height is measured in the direction from an inferior surface of one of the adjacent spinous processes toward a superior surface of the other of the adjacent spinous processes;
inserting a second implant member into the body from the first side after the first implant member, the second implant member comprising third and fourth wings and a second spacer disposed between the third and fourth wings, the third and fourth wings each having a greater height than the second spacer, wherein the height is measured in the direction from the inferior surface of one of the adjacent spinous processes toward the superior surface of the other of the adjacent spinous processes; and
sliding the second implant member along the first implant member until a central portion of the second implant member is substantially aligned with a central portion of the first implant member.

Abstract
Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

5. A method, comprising:
-
inserting a first implant member into a location of a body including a space between adjacent spinous processes along a path in a direction, the first implant member having a distal end portion larger than a proximal end portion along a dimension; and inserting a second implant member along the path after inserting the first implant member; and moving the second implant member in the direction along the first implant member until substantially aligned with the first implant member, the second implant member having a distal end portion smaller than a proximal end portion along the dimension. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method, comprising:
-
inserting a first implant member into a location of a body including a space between adjacent spinous processes from a first side of the adjacent spinous processes, the first implant member comprising first and second wings and a first spacer disposed between the first and second wings, the first and second wings each having a greater height than the first spacer, wherein the height is measured in the direction from an inferior surface of one of the adjacent spinous processes toward a superior surface of the other of the adjacent spinous processes; movingly mating, from the first side, an interface surface of a second implant member with an interface surface of the first implant member to collectively form an interspinous process implant, the second implant member comprising third and fourth wings and a second spacer disposed between the third and fourth wings, the third and fourth wings each having a greater height than the second spacer, wherein the height is measured in the direction from the inferior surface of one of the adjacent spinous processes toward the superior surface of the other of the adjacent spinous processes; and prior to mating the interface surface of the second implant member with the interface surface of the first implant member, distracting the adjacent spinous processes via the first implant member. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A method for inserting a spinal implant comprising:
-
inserting a first implant member into an interspinous space between adjacent spinous processes from a first lateral side of the adjacent spinous processes; while the first implant member is disposed in the interspinous space, inserting a second implant member into the interspinous space from the first lateral side of the adjacent spinous processes; wherein the inserting the second implant comprises coupling the second implant member to the first implant member while the first implant member is disposed in the interspinous space; wherein, when coupled together, at least one of the first and second implant members cradles one of the adjacent spinous processes. - View Dependent Claims (24, 25)
