Abstract
Systems, methods, and kits incorporating a clamp for securing to bone tissue. The clamp includes gripping members to secure the clamp to the bone tissue without the use of screws. The clamp may be used to treat spinal conditions, and may be secured to the spinous process of vertebrae. Systems, methods and kits can incorporate a fusion member configured to fuse between adjacent spinous processes.
Claims28
A system comprising:
- a fusion member configured for insertion between a first spinous process and a second spinous process;
- where the fusion member is H-shaped having two upper and two lower extensions and is secured to the first spinous process between the two upper extensions and the second spinous process between the two lower extensions by one or more protrusions disposed on the inner surface of the upper and lower extensions and oriented inward with respect to each other configured to partially penetrate the first spinous process and the second spinous process;
- and
- where the fusion member further comprises a cage defining a volume for receiving fusion material, said cage defining an opening on a top surface which is configured to be disposed outward with respect to a spine when inserted to receive fusion material, said cage further comprising a plurality of apertures adapted to provide contact area between fusion material and the first and second spinous processes;
- a securement device wherein the securement device is selected from the group consisting of:
- a band, a plate, a pedicle screw, a pedicle screw system, a clamp, a bracket, a wire, a cable, and a prong;
- and
- an adjustment member configured to adjust the circumference of a loop, and wherein the securement device comprises a band that can be configured to form a loop around a first spinous process and a second spinous process.

A fusion member comprising:
- a body comprising a first end and a second end;
- a first concave portion proximal to the first end, wherein the first concave portion is configured to engage a first spinous process;
- and
- a second concave portion proximal to the second end, wherein the second concave portion is configured to engage a second spinous process;
- where the fusion member is secured to the first spinous process and the second spinous process by one or more protrusions disposed on the inner surfaces of the first and second concave portions which are configured to partially penetrate the first spinous process and the second spinous process to provide for attachment to the first and second spinous process and to facilitate stabilization of the fusion member when inserted;
- where the fusion member further comprises a cage defining a volume for receiving fusion material, said cage defining an opening on a top surface which is configured to be disposed outward with respect to a spine when inserted to receive fusion material, said cage further comprising a plurality of apertures adapted to provide contact area between fusion material and the first and second spinous processes.

An interspinous member wherein the interspinous member is configured to engage adjacent spinous processes and comprises:
- a first concave portion configured to engage a first spinous process;
- and
- a second concave portion configured to engage a second spinous process;
- where the interspinous member is secured to the first spinous process and the second spinous process by one or more protrusions configured to partially penetrate the first spinous process and the second spinous process;
- where the interspinous member is configured to promote fusion of the first spinous process and the second spinous process;
- and
- where the fusion member further comprises a cage defining a volume for receiving fusion material, said cage defining an opening on a top surface which is configured to be disposed outward with respect to a spine when inserted to receive fusion material, said cage further comprising a plurality of apertures adapted to provide contact area between fusion material and the first and second spinous processes.
