Bone tissue fixation device and method

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.

         113 . 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 securing member configured to secure the first and second concave portions to the body, said securing member is integrated into the body as a unitary unit.   
     
     
         114 . The fusion member of  claim 113 , is further configured to be set in a lock position by a compression force when secured to the first and second spinous processes. 
     
     
         115 . The fusion member of  claim 113 , 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. 
     
     
         116 . The fusion member of  claim 115 , said cage further comprising a plurality of apertures adapted to provide contact area between fusion material and the first and second spinous processes. 
     
     
         117 . The fusion member of  claim 113 , wherein one or more protrusions are integrated into the first concave portion as a unitary unit. 
     
     
         118 . The fusion member of  claim 113 , wherein one or more protrusions are integrated into the second concave portion as a unitary unit. 
     
     
         119 . 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 is further configured to be set in a lock position by a compression force when secured to the first and second spinous processes.   
     
     
         120 . The fusion member of  claim 119 , further comprises a securing member configured to secure the first and second concave portions to the body, said securing member is integrated into the body as a unitary unit. 
     
     
         121 . The fusion member of  claim 119 , 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. 
     
     
         122 . The fusion member of  claim 121 , said cage further comprising a plurality of apertures adapted to provide contact area between fusion material and the first and second spinous processes. 
     
     
         123 . The fusion member of  claim 119 , wherein one or more protrusions are integrated into the first concave portion as a unitary unit. 
     
     
         124 . The fusion member of  claim 119 , wherein one or more protrusions are integrated into the second concave portion as a unitary unit.
