Abstract
A bone implant includes a first surface and a second surface. The first and second surfaces include a bioresorbable material. A third surface includes a biocompatible material disposed between the first and second surfaces. The third surface extends between a first end and a second end. The first and second ends each include an inner surface defining a cavity configured for disposal of a spinous process. The bioresorbable material of the first and second surfaces is a faster resorbing material than the biocompatible material of the third surface. The third surface provides structural integrity of the implant to maintain distraction between spinous processes so that the first and second surfaces fuse with at least a portion of the spine.
Claims20
A bone implant, comprising:
- a first surface and a second surface, the first and second surfaces comprising a bioresorbable material;
- a third surface comprising a biocompatible material disposed between and connected to the first and second surfaces, the third surface extending between a first end and a second end, the first and second ends each including an inner surface defining a cavity configured for disposal of a spinous process;
- wherein the bioresorbable material of the first and second surfaces is a faster resorbing material than the biocompatible material of the third surface;
- and
- wherein the third surface provides structural integrity of the implant to maintain distraction between spinous processes so that the first and second surfaces fuse with at least a portion of the spine.
A bone implant, comprising:
- a first layer including an upper surface and a lower surface, the first layer comprising a bioresorbable material;
- a second layer comprising a biocompatible material attached to the lower surface of the first layer, the second layer extending between a first end and a second end, the first and second ends each including an inner surface defining a cavity configured for disposal of a spinous process;
- wherein the bioresorbable material of the first layer is a faster resorbing material than the biocompatible material of the second layer;
- and
- wherein the second layer provides structural integrity of the implant to maintain distraction between spinous processes so that the first layer fuses with at least a portion of the spine.
A bone implant, comprising:
- a first bioresorbable polymer mesh bag and a second bioresorbable polymer mesh bag, the first and second mesh bags each comprising demineralized bone chips disposed therein;
- and
- a surface comprising cortical bone, the surface being disposed between and connected to the first and second mesh bags, the surface extending between a first end and a second end, the first and second ends each including an inner surface defining a cavity configured for disposal of a spinous process,
- wherein the surface provides structural integrity of the implant to maintain distraction between spinous processes so that the demineralized bone chips fuse with at least a portion of the spine.
