Smart bone cement injection device

Several problems arise during mini-invasive bone cement injection procedures like vertebroplasty, cementoplasty, kyphoplasty or vertebral augmentation: - cement leaking outside vertebral body at the beginning of operation; - errors due to haste before cement hardens; - practitioner exposed to X-ray from continuous imaging.

We developed a smart device specifically designed to control cement viscosity precisely during mini-invasive bone cement injection procedures: cement can be thickened at the beginning to reach practitioner's ideal consistency before injection. Injection duration is also precisely controlled and standard cement hardening time can be increased up to three times. Thus it provides a lower risk of cement leakage outside vertebral body. To maintain ideal viscosity of the cement, the device automatically adjusts its temperature. Our system includes reusable console and injector, consumable syringe, pipes and trocars (in contact with cement and patient), and is compatible with all commercially available cements, low or high viscosity. If requested, the device can be adapted to a specific cement. This new system is telemanipulated, thanks to remote control, the practitioner can stand or sit, unexposed to X-ray, close to the imaging device console and control all devices.
