The device assists in surgical procedures by providing navigation and burring capabilities but does not directly treat a disease or condition; rather, it aids the surgeon in performing the therapeutic procedure.
No
The Navio system assists in surgical procedures by providing navigation and burring capabilities. It aids in planning and executing the surgical implant location and controls the bur's cutting engagement based on its proximity to the target surface. It does not diagnose medical conditions.
No
The device description explicitly states that the NAVIO system is a "computer-assisted orthopedic surgical navigation and surgical burring system" and includes hardware components such as a passive infrared tracking camera, a surgical drill motor and bur, and a handpiece. The software controls the cutting engagement of the surgical bur, but it is integrated with and controls physical hardware.
Based on the provided information, the Navio system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the system is "intended to assist the surgeon in providing software-defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures." It is used during surgery to guide the surgeon's actions.
- Device Description: The description details a computer-assisted surgical navigation and burring system that interacts directly with the patient's anatomy during the procedure.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information for diagnosis, monitoring, or screening. The Navio system does not perform any such analysis of biological specimens.
The Navio system is a surgical navigation and execution system used in vivo (within the living body) to assist with orthopedic procedures.

Device Description
The NAVIO system is a computer-assisted orthopedic surgical navigation and surgical burring system. The system uses established technologies of navigation, via a passive infrared tracking camera, to aid the surgeon in establishing a bone surface model for the target surgery and in planning the surgical implant location, based on intraoperativelydefined bone landmarks and known geometry of the surgical implant. The NAVIO system then aids the surgeon in executing the surgical plan by using a standard off-theshelf surgical drill motor and bur (Anspach eMax2 Plus System, cleared via K080802), which has been adapted using a tracking system.
The surgical bur is inserted into a handpiece, which allows the bur to move within the handpiece. The NAVIO system software controls the cutting engagement of the surgical bur based on its proximity to the planned target surface. The cutting control is achieved in two ways:
- Exposure control adjusts the bur's exposure with respect to a guard. If the surgeon encroaches on a portion of bone that is not to be cut, the NAVIO system retracts the bur inside the guard, disabling cutting.
- Speed control regulates the signal going to the drill motor controller itself and will limit the speed of the drill if the target surface is approached. This mode of operation is useful in shaping surfaces of the condyle as well as placing post holes and fixation features for femoral and tibial cut guides.
Additionally, the surgeon can disable both controls and operate the NAVIO system handpiece as a standard navigated surgical drill. The surgeon must press on a footpedal to activate the surgical bur and enable cutting in all modes.

Device Description
The NAVIO system is a computer-assisted orthopedic surgical navigation and surgical burring system. The system uses established technologies of navigation, via a passive infrared tracking camera, to aid the surgeon in establishing a bone surface model for the target surgery and in planning the surgical implant location, based on intraoperativelydefined bone landmarks and known geometry of the surgical implant. The NAVIO system then aids the surgeon in executing the surgical plan by using a standard off-theshelf surgical drill motor and bur (Anspach eMax2 Plus System, cleared via K080802), which has been adapted using a tracking system.
The surgical bur is inserted into a handpiece, which allows the bur to move within the handpiece. The NAVIO system software controls the cutting engagement of the surgical bur based on its proximity to the planned target surface. The cutting control is achieved in two ways:
- Exposure control adjusts the bur's exposure with respect to a guard. If the surgeon encroaches on a portion of bone that is not to be cut, the NAVIO system retracts the bur inside the guard, disabling cutting.
- . Speed control regulates the signal going to the drill motor controller itself and will limit the speed of the drill if the target surface is approached. This mode of operation is useful in shaping surfaces of the condyle as well as placing post holes and fixation features for femoral and tibial cut guides.
Additionally, the surgeon can disable both controls and operate the NAVIO system handpiece as a standard navigated surgical drill. The surgeon must press on a footpedal to activate the surgical bur and enable cutting in all modes.

UKR and PFA Overview
In the UKR and PFA applications, the NAVIO system uses established technologies to prepare bone for attachment of implant components. The NAVIO system uses intraoperative data collection (image-free or non-CT data generation) to create a model of the patient's femur and/or tibia, depending on the procedure being performed, and allows the surgeon to prepare a surgical plan. The NAVIO system uses pre-defined boundaries generated during the planning process to control the motion of the surgical bur and limit the amount of bone removed in order to shape the condyles, tibial plateau, or patellofemoral joint in preparation for placement of the surgical implant.
TKA Overview
Similar to the UKR and PFA applications, the TKA application uses intraoperative data collection to create a model of the patient's femur and tibia and allows the surgeon to prepare a surgical plan. In the TKA application, the NAVIO system is used to plan the location of the femur and tibia implants, as well as cut guides and position the features used to secure the cut guides in place. The NAVIO system controls the cutting action of the bur during placement of the femur and tibia cut guides. The surgeon finishes the preparation of the bone surface using standard surgical saws, guided by the slots in the cut guides. Cutting action of the saw is not controlled by the NAVIO system. The surgeon follows the implant manufacturer's recommended procedure to remove bone and place the implant, just as if the cut guide had been placed manually. The manual instrumentation technique established by each implant's manufacturer is used to prepare the remainder of the bone surface to receive the total knee implant components.
One of the enhancements to the TKA application software is the addition of a Bur All feature that enables the surgeon to prepare bone for the attachment of total knee implant components. Using the same method of bone removal as the UKR and PFA applications, the NAVIO system controls the bur either by retracting the bur in a guard (Exposure Control) or by controlling the speed of the bur (Speed Control) as the target surface is approached. The Bur All feature also provides a way for a surgeon that performed bulk bone removal using a standard surgical saw to refine the bone model and make additional fine cuts to clean up the bone surface to receive the implant.
The following diagram shows the primary workflow steps in each application: UKR, PFA, and TKA. The three procedures are mutually independent and cannot be planned or completed in parallel. Note: The workflows for UKR and PFA procedures have not changed from the predicate device, cleared via K160537.

Discussion of Similarities and Differences
The NAVIO system presented in this 510(k) submission is substantially equivalent to the predicate NAVIO, K160537. The intended use, indications for use, and the general functionality of the NAVIO system are unchanged from the previously submitted device.
This submission supports the following updates to the NAVIO system:
- the addition of the Smith & Nephew LEGION Total Knee System CR/PS and GENESIS II Total Knee System CR/PS to the list of supported implants,
- . updates to the NAVIO TKA instrument kit and components, and
- feature enhancements to the NAVIO system Total Knee Application software. ●
The implant product codes supported by the subject device are consistent with the predicate device. The LEGION Total Knee System CR/PS and GENESIS II Total Knee System are cemented implants that share the product code JWH, a currently supported NAVIO product code. These implants have been successfully imported and appropriately validated for use with the NAVIO system.
The NAVIO TKA instrument kit was updated to include two new components: a new femur drill guide to support the LEGION-GENESIS II CR/PS implants and a new Twin Peg Tibia Cut Guide.
Feature enhancements were made to the NAVIO TKA application software. The NAVIO system TKA workflow, described in K160537, has been updated to improve usability of the application, simplify the user interface to remove features that were not being utilized, and to introduce new features. One of the primary features that is being introduced is the option to use the NAVIO handpiece to bur away all bone necessary to accurately place a total knee implant component; this functionality is similar to the UKR and PFA applications.
The established technologies that are used by the NAVIO system to prepare bone for attachment of implant components or for the attachment of the TKA femur and tibia cutting guides are unchanged.

Conclusions
The NAVIO system described in this submission has the same intended use and the same technological characteristics as the NAVIO system, most recently cleared per K160537. The differences in the methodology of bone removal between the previously cleared NAVIO system (K160537) and the additional supported total knee implant systems, as well as updated instrumentation, and software feature enhancements, do not raise any new questions of safety or effectiveness.
The key determining factor is whether NAVIO control can be applied accurately to accomplish the desired cutting in accordance with the plan without exceeding the predefined limits. The accuracy verification testing performed indicates that the total knee implant placement accuracy using Bur All method of bone removal is acceptable and similar to the implant placement accuracy required for unicondylar and patellofemoral implant placement. Additionally, placement of the LEGION CR/PS and GENESIS II CR/PS Total Knee Implant systems using the NAVIO TKA cut guides (including the new Tibia Twin Peg cut guides) is acceptable and similar to the placement accuracy presented in the previous 510(k). Usability validation testing demonstrated that surgeon users were able to perform a TKA procedure on cadaver in a simulated operating room environment safely and effectively using the NAVIO system with TKA application.
The NAVIO system presented in this 510(k) premarket notification demonstrates that the updated NAVIO system, with these additional supported total knee implants, instrument tray and component changes, and software feature enhancements, continues to be as safe and effective as the predicate NAVIO system (K121936, K140596, K143668, K152574, and K160537).
