Today’s Patent – Total Joint Replacement Infection Control Devices and Methods

The said invention (US12257154B2) was invented by Brian C. de Beaubien, Brian Bowman, Benjamin Arnold Erika Lin, Kristen Pena, Tina John, and patented by USPTO on July 19^th, 2024. Currently, it stands assigned to the Osteal Therapeutics Inc.

This invention provides an orthopedic system for delivering therapeutic agents, such as antibiotics, into a bone’s intramedullary canal or joint. It includes one or more elongate stems with internal channels and radial protrusions that anchor into bone while allowing fluid to exit through strategically placed outlet holes. A coupling member connects multiple stems (e.g., femur and tibia) and includes an inlet for agent delivery. The coupling can be fixed or adjustable to fit patient anatomy.

The system may feature pumps for agent infusion or fluid removal, and may integrate with joint implants like femoral heads or acetabular cups. Components may include threaded, snap-fit, or flanged connectors, and the stems may be partially hollow or selectively bone-contacting to optimize delivery. Methods include positioning the stems, adjusting spacing, and delivering agents through internal channels to target areas.
