Abstract: A self-drilling bone fusion screw apparatus is disclosed which includes at least first and second sliding boxes. A first screw member having a tapered end and a threaded body is disposed within the first sliding box, and a second screw member having a tapered end and a threaded body disposed within the second sliding box. An adjuster adjusts the height of the sliding boxes. The screw members are screwed into vertebral bodies in order to fuse the vertebral bodies together. A plurality of the self-drilling bone fusion screw apparatuses may be attached together and/or integrated via a plate or cage. Also disclosed is a cervical facet staple that includes a curved staple base and at least two prongs attached to the bottom surface of the curved staple base. [cite: The patent text provided by the user includes this information in the "Abstract" field.]

Plain-Language Overview of Independent Claims:

  • Independent Claim 1: This claim describes a self-drilling bone fusion screw apparatus. It consists of a first and a second sliding box, along with an adjuster to change their height. Inside each sliding box is a screw member with a tapered end and a threaded body. The claim specifies that these screws are inserted into vertebral bodies to achieve fusion.
  • Independent Claim 12: This claim also describes a self-drilling bone fusion screw apparatus. It features a single box containing two screw members, each with a tapered end and a threaded body, laterally aligned within the box. Additionally, the box has multiple ridges along its sides.
  • Independent Claim 14: This claim presents another self-drilling bone fusion screw apparatus. It includes a first box with a laterally aligned screw member (tapered end, threaded body), a second box with a laterally aligned screw member (tapered end, threaded body), and an attachment member that connects the first and second boxes.
  • Independent Claim 19: This claim describes a tool assembly designed to manipulate the self-drilling bone fusion screw apparatuses. It comprises a handle, a gripper with prongs that works with the handle, and a screw guide held by the prongs. The screw guide's purpose is to control the direction of the self-drilling screws as they are inserted into a vertebral body.
  • Independent Claim 23: This claim defines a cervical facet staple. It has a curved staple base, at least two prongs attached to the bottom surface of this base, and an insertion member located on the top surface of the curved staple base.
  • Independent Claim 26: This claim describes an impaction tool specifically for a cervical facet staple. It includes a handle, a stem connected to the handle, several wings for contacting the cervical facet staple, and an insertion member that couples the cervical facet staple to the tool.
  • Independent Claim 29: This claim details a lumbar facet staple. It consists of a pair of rotating arms, at least two prongs attached to the inner surfaces of these arms, multiple spurs on one of the rotating arms, and a ratchet also attached to one of the rotating arms. The rotating arms and prongs are designed to close to staple a lumbar facet joint.

Regarding CAFC 2026 dockets for patent 9005293, the provided search results indicate general CAFC activity in 2026, including decisions on obviousness, patent eligibility, and various appeals. However, none of the provided search results specifically mention US patent 9,005,293 in relation to any CAFC dockets for 2026. Therefore, I cannot authoritatively state whether there is any specific CAFC litigation involving this patent in 2026. The patent information on Google Patents (which is part of the provided text) notes "PTAB case IPR2025-01598 filed (Pending - Instituted) litigation Critical", but this is a PTAB case, not a CAFC docket, and is for 2025, not 2026.
