Intraosseous Device Including Sensing Obturator
Summary
The USPTO granted Patent US12599405B2 to Bard Access Systems, Inc. covering an intraosseous access system with a driver, needle, and sensor-equipped obturator. The system detects modality changes via an electrical impedance sensor including a passive RFID chip. The patent contains 10 claims and covers the device's control logic that modifies driver operation upon detecting changes.
What changed
The USPTO issued Patent US12599405B2 to Bard Access Systems, Inc. for an intraosseous access system featuring a driver with control logic, a needle assembly, and an obturator with an electrical impedance sensor. The sensor includes a passive RFID chip that activates upon detecting a change in modality, allowing the driver to modify its operation accordingly.
Healthcare and medical device companies developing or using intraosseous access devices should review this patent for freedom-to-operate considerations. The patent's claims covering sensor-based modality detection and RFID-enabled obturators may affect product development strategies and could require licensing negotiations with Bard Access Systems.
What to do next
- Monitor patent landscape for competing technologies
- Review patent claims for potential licensing or design-around opportunities

Abstract
An intraosseous access system includes a driver, a needle, and an obturator positioned in the needle to prevent entry of bodily tissues into the lumen. The driver includes control logic configured to modify operation of the driver upon an indication that a change in modality is detected. The obturator includes a sensor such as an electrical impedance sensor. The electrical impedance sensor can include a passive RFID chip configured to activate when the change in modality is detected.
