Systems and methods for robotically preparing a disc space are provided for implantation of an intervertebral prosthetic disc. The system includes three-dimensional modeling to identify positions of vertebrae adjacent a surgical site and a disc selection interface in a computing system to allow the surgeon to select an intervertebral disc prosthesis for implantation. A bone cutting interface allows the surgeon to determine a bone cutting pattern tailored to both the three-dimensional positions of the vertebrae and the selected intervertebral disc. A robot controls a cutting device or guides a cutting device to cut the vertebral bone in the bone cutting pattern.

A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.

Disclosed is a standalone anterior lumbar interbody spacer that includes a lumbar spacer body and lumbar plate with a unique locking system to rigidly couple the spacer body and plate via a spring loaded lock tab.

This disclosure includes an expansion driver for adjusting expandable implants, the expansion driver including: a first driver having a first gear disposed at a first end thereof; and a second driver having a second gear disposed at a first end of the second driver; and a handle operably connected to the first driver and the second driver, the handle having at least one bevel gear rotatably attached thereto, the at least one bevel gear engaging each of the first gear and the second gear; wherein upon a rotation of the handle a torque is applied to at least one of the first driver or the second driver.

A spinal jack adapted for installation between first and second vertebral processes, including first and second inter-expandable jack halves arranged between retracted and expanded positions. Each of the jack halves further includes gripping portions adapted for engaging the vertebral processes. A worm gear mechanism provides for expanding or retracting the jack halves in order to establish a corrected adjusted orientation between the processes and includes each of stationary rotatable slave gears along with support stems with integrated worm gear interfaces for expanding the jack halves relative to each other.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

The disclosure provides an implant including first and second interconnected elongated articulating portions with vertebral contacting outer surfaces. The first and second interconnected elongated articulating portions have a first configuration for insertion into a disc space and a second configuration upon deployment in the disc space. In a first configuration the axes of the first and second interconnected elongated articulating portions are substantially axially aligned with each other and in a second configuration the axes of the portions are axially unaligned with each other. The first and second interconnected elongated articulating portions are configured to be deployed in situ from the first configuration to the second configuration by both pivoting. The implant is expandable in the height direction between the vertebral contacting outer surfaces while the implant is inside the disc space by sliding a portion of at least one of the first and second elongated articulating portions.

A bone fusion method, system and device for insertion between bones that are to be fused together in order to replace degenerated discs and/or bones, for example, the vertebrae of a spinal column. The bone fusion device comprises a frame and one or more extendable plates that are able to be angled, rotatable, adjustable, and have top profiles designed to correct and/or match the replaced discs/bones. The bone fusion device is able to be inserted between or replace the vertebrae by using a minimally invasive procedure wherein the dimensions and/or other characteristics of the bone fusion device are selectable based on the type of minimally invasive procedure.

An implantable prosthesis that includes a biased coiling member and a conforming coiling member. The biased coiling member may be biased to curve from a substantially linear configuration to a nonlinear configuration. The conforming coiling member may be engaged with and curved by the biased coiling member from the substantially linear configuration to the nonlinear configuration. The biased coiling member may define a longitudinal axis when in the substantially linear configuration. The biased coiling member and the conforming coiling member may move relative to each other along the longitudinal axis. The prosthesis may be implanted in a surgical procedure that minimizes incision sizes and may be considered less invasive than typical implant procedures, especially spinal implant procedures.
