South Carolina Patent of the Month – May 2024

The field of medical devices is constantly evolving to address the intricate needs of patients, particularly in cases of bone degeneration and spinal instability. One notable advancement in this realm comes from DeGen Medical, Inc., who have developed an innovative solution in the form of expandable intervertebral spacers.

These spacers, designed with a meticulous attention to detail, offer a transformative approach to spinal support and alignment. Unlike static spacers that may require multiple trialing and pose risks such as impaction or breakage, DeGen’s expandable intervertebral spacers boast a unique mechanism that allows for in-situ expansion, streamlining the placement process and minimizing potential complications.

At the heart of this invention lies a sophisticated design comprising a main body, driving member, endplates, and an actuation member. The main body, with its precisely crafted openings and curvilinear surfaces, serves as the foundation for the spacer’s functionality. Meanwhile, the driving member, strategically positioned within the interior chamber, plays a pivotal role in facilitating controlled expansion.

What sets DeGen’s expandable intervertebral spacers apart is their simplicity without sacrificing efficacy. The driving member, equipped with a series of steps, enables smooth linear movement upon rotational actuation, effortlessly transitioning the spacer from an unexpanded to an expanded configuration. This mechanism ensures precise control over the expansion process, enhancing safety and reliability during implantation.

The incorporation of endplates further enhances the spacer’s structural integrity and compatibility with the vertebral anatomy. These endplates, meticulously designed with curvilinear surfaces and protrusions, ensure optimal interfacing and stability within the spinal column, minimizing the risk of displacement or malalignment post-implantation.

Beyond their structural ingenuity, DeGen’s expandable intervertebral spacers embody a commitment to patient-centric innovation. By addressing the shortcomings of existing spacer designs, such as complexity in manufacturing and limited space for bone graft material, this invention paves the way for improved clinical outcomes and enhanced patient satisfaction.
