Patents by Inventor Gerhard Rivera

Gerhard Rivera has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20260183123
    Abstract: An implant removal tool designed for efficient and precise removal of an acetabular cup or similar implants is disclosed. The tool includes an outer shaft and an internal shaft configured to move relative to the outer shaft. The internal shaft is operably connected to a cutting assembly comprising multiple inwardly curving, wedge-shaped blades. The blades transition from a retracted position to a closed position, forming a semicircular cutting path slightly larger than the outer diameter of the implant. This configuration allows for controlled rotation of the blades around the implant's outer surface, effectively severing surrounding bone while minimizing damage to adjacent bone and soft tissues. The tool may include interchangeable components to accommodate implants of varying sizes, ensuring adaptability across surgical scenarios. Additional features, such as a helical thread mechanism or drill compatibility, enhance usability and precision during revision surgeries.
