No
The description focuses on stereotaxic technology, infrared tracking, and real-time display of measurements based on anatomical landmarks, which are standard computer-assisted surgery techniques and do not inherently involve AI/ML. There is no mention of learning, training data, or algorithms that adapt or improve over time.
No
The device aids the surgeon in surgical procedures and instrument/implant positioning by providing information, but it does not directly treat or diagnose a disease.
No
The device provides real-time support and information to the surgeon during orthopedic surgical procedures for instrument and implant positioning, rather than diagnosing a patient's condition.
No
The device description explicitly lists hardware components including infrared cameras, a computer, a monitor, interface devices (keyboard, foot pedal, mouse), and manual reusable surgical instruments, in addition to the software.
Based on the provided information, the iMNS Medacta Navigation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- iMNS Medacta Navigation System Function: The description clearly states that the system is used during surgical procedures to assist the surgeon with instrument and implant positioning based on anatomical landmarks and intra-operative data. It uses an infrared camera to track markers on the patient's bones and instruments.
- No Specimen Analysis: There is no mention of the system analyzing any biological specimens taken from the patient. Its function is entirely focused on real-time spatial tracking and guidance during surgery.
Therefore, the iMNS Medacta Navigation System falls under the category of a surgical navigation system or computer-assisted surgery device, not an In Vitro Diagnostic device.

Device Description
The iMNS Medacta Navigation System is a device for computer aided navigation of surgical instruments used in total knee replacement surgery. The system works on the common principle of stereotaxic technology in which passive markers are securely mounted on the patient's bones and an infrared camera is used to monitor the spatial location of those marker and and information is used to locate the anatomical landmarks such as centers of rotation of the femur head, knee and ankle intraoperatively. These measurements are displayed on a computer screen in real time. The instruments are then outfitted with the passive markers to improve the positioning of the cutting guides. The information from the system with the "navigated" instruments assists the surgeon in optimally conducting the bone resections and positioning of the orthopedic surgical implants. The surgeon maintains control of the surgery and makes any decisions required with regard to bone resections and implant positioning but the iMNS Medacta Navigation System provides real time support and information throughout the surgery.
The iMNS Medacta Navigation System consists of the following key components:
- An acquisition system composed of two infrared cameras equipped with infrared light emitting diodes (LED) to track the position of the passive markers,
- A computer running the proprietary Medacta software and a monitor,
- Interface devices of a keyboard, foot pedal and optional mouse to control the system, and
- Manual reusable surgical instruments.
The software application called Evolis Global Femur First is designed to work with Medacta's Evolis Total Knee System, cleared under K081023. The manual reusable surgical instruments include instruments specifically designed for navigated surgery and other standard surgical instruments needed to conduct total knee replacement.
