The description focuses on image processing for 3D model reconstruction and tracking, without mentioning AI or ML algorithms for decision support, analysis, or prediction.
No.
The device is a surgical navigation system intended to assist in the positioning of hip replacement components, not to directly treat a disease or condition.
No
The device is described as a stereotaxic instrument to assist in the positioning of hip replacement components, functioning as an image-guidance system. It is used intra-operatively to guide component placement based on pre-operative imaging. It does not diagnose medical conditions.
No
The device description explicitly states that the system consists of a software-driven workstation, an optical tracking system, surgical instruments, and tracking accessories, indicating the presence of hardware components beyond just software.
Based on the provided information, the Navitrack™ System – Total Hip Replacement is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Navitrack System's Function: The Navitrack System is a surgical navigation system. Its purpose is to assist the surgeon during surgery by providing real-time guidance for positioning hip replacement components based on pre-operative imaging. It does not analyze biological specimens from the patient.
- Intended Use: The intended use clearly states it's a "stereotaxic instrument to assist in the positioning of hip replacement components" and "intended to assist in precisely positioning hip replacement components intra-operatively." This is a surgical aid, not a diagnostic test performed on a sample.
- Device Description: The description details a system involving a workstation, tracking system, instruments, and software for image processing and planning. This aligns with a surgical navigation system, not an IVD.
Therefore, the Navitrack™ System – Total Hip Replacement falls under the category of a surgical guidance or navigation system, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Navitrack™ System - Total Hip Replacement is indicated for use as a stereotaxic instrument to assist in the positioning of hip replacement components. It is a computer controlled image-guidance system that integrates a three-dimensional tracking sub-system and image-processing software. It is intended to assist in precisely positioning hip replacement components intra-operatively by displaying their positions relative to the bone structures of interest that are modeled pre-operatively from radiology images.

Device Description
The Navitrack™ System - Total Hip Replacement device consists of a software-driven workstation, an optical tracking system, surgical instruments, and tracking accessories. It is designed to assist the surgeon in the placement of Total Hip Replacement (THR) components. Tracking devices are incorporated with given surgical instruments, as well as onto fixation bases that attach to the pelvis, such to allow the ability to track and display to the user their respective positions intra-operatively. The bones of interest are displayed to the user as three-dimensional (3D) surface models, while the instruments are schematically represented. Models of the implant are also represented in order to visualize their placement using the instruments. The 3D models of the pelvis are reconstructed pre-operatively from given CT-images using image processing tools provided with the software. The software also provides planning features by allowing the user to determine pre-operatively an ideal location for the implants as based on the models.

Date Summary Prepared: July 19, 2002
Device Trade Name: Navitrack™ System - Total Hip Replacement
Device Classification Name: Stereotaxic Instrument (84 HAW); 21 CFR § 882.4560
Reason for 510(k) Notification: Modifications of indications and technology to a currently cleared device from Orthosoft Inc.
Susbtantial Equivalence Claimed To:
The Navitrack System™ - Optical Option, from Orthosoft Inc. (K002053) The VectorVision® Hip, from BrainLAB AG (K010602)
Device Description:
The Navitrack™ System - Total Hip Replacement device consists of a software-driven workstation, an optical tracking system, surgical instruments, and tracking accessories. It is designed to assist the surgeon in the placement of Total Hip Replacement (THR) components. Tracking devices are incorporated with given surgical instruments, as well as onto fixation bases that attach to the pelvis, such to allow the ability to track and display to the user their respective positions intra-operatively. The bones of interest are displayed to the user as three-dimensional (3D) surface models, while the instruments are schematically represented.

positioning hip replacement components intra-operatively by displaying their positions relative to the bone structures of interest that are modeled pre-operatively from radiology images.
Technological Comparisons to Substantial Equivalent Devices:
The comparisons showed that the proposed product is equivalent to both the Navitrack and the VectorVision Hip predicates in terms of the workstation and the tracking technology. The only significant departures of the proposed product relative to the predicates consisted in the intended use of the proposed device in THR procedures unlike in the Navitrack predicate. However, the VectorVision Hip predicate includes this intended use as well as also being otherwise equivalent.
Performance Data:
Non-clinical tests were performed to assess that no new safety and efficacy issues were raised in the device. They consisted in verifying that the accuracy and performance of the system was adequate to perform as intended.
Conclusion:
The information and data provided in this 510(k) Premarket Notification established that the Navitrack™ System - Total Hip Replacement device is substantially equivalent to the legally marketed predicates: the Navitrack System™ - Optical Option, and the VectorVision® Hip.
