No
The description focuses on stereotaxic technology, infrared tracking, and real-time display of measurements based on anatomical landmarks. There is no mention of AI, ML, or related concepts like training data, algorithms, or performance metrics typically associated with AI/ML systems.
No.
The device provides real-time information and support to the surgeon for precise instrument and implant positioning during surgery, rather than directly treating a disease or condition. It is a navigational aid, not a therapeutic agent itself.
No
Explanation: The device provides real-time information and assistance to surgeons during orthopedic surgical procedures (like total knee replacement) to aid in instrument and implant positioning and bone resections. It does not diagnose medical conditions.
No
The device description explicitly lists hardware components beyond just a computer running software, including infrared cameras, interface devices (keyboard, foot pedal, mouse), and manual reusable surgical instruments.
Based on the provided information, the iMNS Medacta Navigation System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the system is used to support the surgeon during specific orthopedic surgical procedures by providing information on bone resections, instrument, and implant positioning. This is an in vivo application, meaning it is used within a living organism (the patient) during surgery.
- Device Description: The description details a system that uses infrared cameras and passive markers attached to the patient's bones to track spatial location and assist the surgeon in real-time during surgery. This is a surgical navigation system, not a device that analyzes biological samples in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, urine, etc.), performing tests on these samples, or providing diagnostic information based on such analysis.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The iMNS Medacta Navigation System does not fit this definition. It is a surgical tool that provides real-time guidance during a surgical procedure.

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 markers. This 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 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 GMK v4.2.2 is designed to work with Medacta's GMK Total Knee System, cleared under K090988. The manual reusable surgical instruments include instruments specifically designed for navigated surgery and other standard surgical instruments needed to conduct total knee replacement.

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 kev 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 GMK v4.2.2 is designed to work with Medacta's GMK Total Knee System, cleared under K090988. The manual reusable surgical instruments include instruments specifically designed for navigated surgery and other standard surgical instruments needed to conduct total knee replacement.
Indications for Use:
The iMNS Medacta Navigation System is intended to be used to support the surgeon during specific orthopedic surgical procedures by providing information on bone resections, instrument and implant positioning during joint replacement.
The iMNS Medacta Navigation System provides computer assistance to the surgeon based on anatomical landmarks and other specific data obtained intra-operatively that are used to place surgical instruments.

Performance Testing
No performance standards applicable to this device have been adopted under Section 514 of the Food, Drug and Cosmetic Act. Performance testing of the iMNS Medacta Navigation System was conducted in accordance with design controls, international standards and FDA guidance documents.
Comparison to Predicate Device
The indications for use of the modified system remain the same as the original 510(k) K083872.
The iMNS Medacta Navigation System v4.2.2 is identical to the predicate device, iMNS Medacta Navigation System v4.0 in the following aspects: Intended Use/Indications for Use, design features, operating principle, type of optical tracking system, graphical user interface, control switch, passive locators, navigated surgery process, sterility, and biocompatibility aspects.

The main difference between the iMNS Medacta Navigation System v4.2.2 and the predicate device is the software application. Previously there was only one software application, Evolis Global Femur First version 4.0 (K083872) and the second software application is GMK version 4.2.2 which is the subject of this 510(k).
The manual reusable surgical instruments have changed to those required by the non-navigated GMK Total Knee System. Additionally, there are separate micrometric positioners that are specific to GMK included with the instruments for use with navigated knee surgery and the iMNS Medacta Navigation System. These manual surgical instruments are made of the same type of materials as those in the original submission and handled the same as other reusable manual orthopedic instruments for non-navigated surgery.
The iMNS Medacta Navigation System was tested as part of design verification and validation to written protocols with pre-defined acceptance criteria. The testing met all acceptance criteria. This new software version has been completely verified and validated like an initial software release. The verification and validation activities are summarized in the below.
