DEVICE: Curve Navigation 17700 (04056481142520)

An assembly of electromechanical devices used during orthopaedic computer assisted surgery (CAS) as a functional extension of the surgeon for precise procedural movement and placement (navigation) during the procedure (e.g., placement of a pedicle screw in spinal surgery). It is computer-based and typically consists of, e.g., an operator's console and a video camera used to track the instrumentation. The input to the computer is usually by means of an existing CT or MRI scan that is used as a template. The system tracks the instrumentation by reading the location points giving a three-dimensional (3-D) picture of the instrument's position/angulation. It can also be used as a training aid.

A mobile assembly of electrically-powered devices intended to provide a physician with both electromagnetic (EM) and optical tools to track manual surgical instruments and locate target anatomical structures with respect to pre-acquired images (e.g., CT/MRI scan) or real-time data [e.g., endoscopic, ultrasound (US)] during computer assisted surgery (CAS). It consists of a workstation with controls/display, an EM field generator, a camera, and sensors/spatial markers for attachment to the patient and instruments for position/movement tracking. It is used for multiple procedures (e.g., craniotomy) in various fields [e.g., ear/nose/throat (ENT), craniomaxillofacial (CMF) surgery].
