Intended Use
The Navitrack™ System - Total Hip Replacement CT-Free Cup 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 equipped with a three-dimensional tracking sub-system. It is intended to assist in precisely positioning hip replacement components intra-operatively by displaying their positions relative to the joint's alignment axes as based on user-identified anatomical landmarks.
Device Description
The Navitrack™ System - Total Hip Replacement CT-Free Cup 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 on to 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 pelvis is displayed to the user in the form of its main alignment axes. The alignment axes are determined and recorded intra-operatively by identifying the key anatomical references that are used clinically to align and position the THR components. The instruments are schematically represented.
More Information

No
The description focuses on computer-controlled image guidance, 3D tracking, and user-identified anatomical landmarks for positioning. There is no mention of AI, ML, or related concepts like training/test sets, performance metrics typically associated with AI/ML models, or complex image processing beyond basic tracking and display.

No.
The device assists in positioning hip replacement components, which is a tool for surgery, not a direct therapeutic intervention itself.

No

The device is described as an image-guidance system intended to assist in positioning hip replacement components during surgery, rather than diagnosing a condition or disease.

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 CT-Free Cup is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
  • Navitrack System's Function: The Navitrack System is a surgical guidance system used intra-operatively to assist in the positioning of hip replacement components. It uses tracking and image guidance based on anatomical landmarks identified on the patient's body during surgery.
  • No Specimen Examination: The system does not examine any specimens (blood, tissue, etc.) from the human body in vitro. Its function is to guide the surgeon's actions during the surgical procedure itself.

Therefore, the Navitrack™ System falls under the category of a surgical guidance or navigation system, not an In Vitro Diagnostic device.

Date Summary Prepared: March 12, 2002

Device Trade Name: Navitrack™ System - Total Hip Replacement CT-Free Cup

Device Classification Name: Stereotaxic Instrument (84 HAW); 21 CFR § 882.4560

Predicate Devices: Navitrack System™ - Total Hip Replacement; from Orthosoft Inc; 510(k) #K022364

Device Description:

The Navitrack™ System - Total Hip Replacement CT-Free Cup 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.

Technological Comparisons to the Predicate:

The comparisons showed that the proposed device is substantially equivalent to the Navitrack System - Total Hip Replacement predicate. It is a modification to the predicate. The fundamental scientific technology of the predicate is unchanged. It utilizes the same workstation and tracking technology. The main difference is in the technique with corresponding changes in the software. Instead of determining the alignment axes from 3-D model representations of the bones of interest that were created from CT-Scan images pre-operatively, in the proposed device the alignment axes are determined by digitizing key anatomical landmarks directly on the bone of interest intraoperatively. The instruments are equivalent incorporating minor modifications in relation to the new proposed technique.

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 as compared to the predicate.

Conclusion:

The information and data provided in this 510(k) Premarket Notification established that the Navitrack "10 System - Total Hip Replacement CT-Free Cup device is substantially equivalent to the Navitrack System™ - Total Hip Replacement predicate.
