Abstract
In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.
Core Innovation
The core invention is an orthopedic implant having an external frame defining an exterior surface, where the external frame is defined by a plurality of planar truss units arranged in a series with an angle relative to one another to form an enclosure having substantially vertical walls defined by the planar truss units, with the planar truss units arranged in a vertical direction from a bottom surface of the implant toward a top surface of the implant. The implant includes an internal web structure at least partially enclosed by the external frame and configured to interface with bone tissue.
The internal web structure comprises a space truss having two or more planar truss units with a plurality of struts joined at nodes, where the space truss includes planar truss units forming one or more polyhedron truss units. At least one polyhedron truss unit of the web structure passes into a central portion of the implant, thereby establishing a space-truss arrangement within the implant while maintaining interface with bone tissue.
The disclosed implant arrangement includes polyhedron truss unit center regions and void regions as part of the space truss. In one embodiment, the center portion of the polyhedron truss units has a void region in their center that does not include any additional members extending there through, while at least one polyhedron truss unit passes into a central portion of the implant.
Claims Coverage
The document includes three independent claims. Across these claims, the inventive features focus on an implant with an external frame formed by planar truss units, an internal bone-interface space truss formed by planar truss units joined at nodes to create polyhedron truss units, and a central portion behavior including passage of at least one polyhedron truss unit into the implant center and, in one claim, an internal void region without additional members extending through.
External frame enclosure defined by planar truss units
An implant for interfacing with a bone structure comprising an external frame defining an exterior surface of the implant, wherein the external frame is defined by a plurality of planar truss units arranged in a series with an angle relative to one another forming an enclosure having substantially vertical walls defined by the planar truss units with the planar truss units arranged in a vertical direction from a bottom surface of the implant toward a top surface of the implant.
Internal space truss of planar truss units joined at nodes forming polyhedron truss units
An implant further including an internal web structure at least partially enclosed by the external frame configured to interface with bone tissue, the internal web structure comprising a space truss comprising two or more planar truss units having a plurality of struts joined at nodes, wherein the space truss comprises planar truss units forming one or more polyhedron truss units.
Polyhedron truss unit passing into central portion
An implant wherein at least one polyhedron truss unit of the web structure passes into a central portion of the implant.
Void region in center portion of polyhedron truss units without additional members extending through
An implant wherein the internal web structure comprises a space truss comprising a plurality of polyhedron truss units, wherein the center portion of the polyhedron truss units have a void region in their center that does not include any additional members extending there through, and wherein at least one polyhedron truss unit of the web structure passes into a central portion of the implant.
Accessing a space and inserting an implant with a planar-truss external frame and central polyhedron truss unit
A method comprising accessing a space proximate a bone structure comprising bone tissue and inserting an implant into the space, wherein the implant comprises an external frame defined by planar truss units arranged in a series with an angle relative to one another forming an enclosure having substantially vertical walls, and an internal web structure with a space truss of planar truss units joined at nodes forming polyhedron truss units, wherein at least one polyhedron truss unit of the web structure passes into a central portion of the implant.
The claim coverage is centered on combining an external frame enclosure defined by angular planar truss units producing substantially vertical walls, an internal bone-interface space truss made from planar truss units with struts joined at nodes and forming polyhedron truss units, and a central-region feature in which at least one polyhedron truss unit passes into the implant’s central portion, with one claim further requiring a void region in the center of polyhedron truss units without additional members extending through.
