Enhanced Expandable Fusion Device with Real-time Feedback and Customization
Legal Citation
Summary of the Inventive Concept
An advanced expandable fusion device that integrates sensors for real-time feedback, self-locking mechanisms, and modular design for customized patient fit, enhancing the intervertebral fusion process.
Background and Problem Solved
The original expandable fusion device patent, while effective, has limitations in providing real-time feedback to surgeons, ensuring device stability, and accommodating varying patient anatomies. The new inventive concept addresses these limitations by introducing integrated sensors, self-locking mechanisms, and modular design.
Detailed Description of the Inventive Concept
The enhanced expandable fusion device features a central ramp with an integrated sensor that provides real-time feedback to surgeons during installation, enabling more precise and effective fusion. The device is also equipped with a self-locking mechanism that ensures it remains in place after installation, reducing the risk of device migration. Furthermore, the modular design allows for interchangeable endplates and central ramps, customizing the device to fit different patient anatomies. The device can adjust its width and height in real-time based on the patient's anatomy, ensuring a secure and efficient fusion process.
Novelty and Inventive Step
The new claims introduce the integration of sensors, self-locking mechanisms, and modular design, which are not present in the original patent. These features provide a significant improvement in the intervertebral fusion process, making the new inventive concept novel and non-obvious.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include variations in sensor technology, self-locking mechanisms, and modular design configurations. For example, the sensor could be replaced with a different type of feedback mechanism, or the self-locking mechanism could be modified to accommodate different device geometries.
Potential Commercial Applications and Market
The enhanced expandable fusion device has significant commercial potential in the spinal surgery market, offering improved patient outcomes, reduced surgical time, and increased surgeon confidence. The target industries include medical device manufacturers, hospitals, and orthopedic clinics.
