Intended Use
The Navitrack™ System - Total Hip Replacement CT-Free 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
Identically as in the predicate, the Navitrack™ System – Total Hip Replacement CT-Free device consists of a software-driven workstation, an optical tracking system, surgical instruments, and tracking accessories, 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 intraoperatively. 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 kev anatomical references that are used clinically to align and position the THR components. The instruments are schematically represented. The modifications to the predicate are to additionally track the femur and femoral instrumentation similarly as is done for the pelvis, in order to also assist in the placement of the THR components for the femur.

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 for algorithmic learning.

No
The device is an image-guidance system intended to assist in precisely positioning hip replacement components intra-operatively, not to directly treat or diagnose a disease.

No

Explanation: The device is described as assisting in the positioning of hip replacement components by displaying their positions relative to joint alignment axes. It is an image-guidance system for surgical assistance, not a device used to diagnose a medical condition.

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 it includes hardware components beyond just software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Navitrack™ System is a surgical navigation system. It assists surgeons during surgery by providing real-time guidance for positioning implants based on anatomical landmarks. It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states it is a "stereotaxic instrument to assist in the positioning of hip replacement components." This is an intra-operative surgical aid, not a diagnostic test.
  • Device Description: The description details a system with a workstation, tracking system, instruments, and accessories used to track and display the position of surgical components and anatomical structures during surgery.

The device is a surgical guidance system, not a diagnostic tool that analyzes biological samples.

510(K) SUMMARY OF SAFETY AND EFFECTIVENESS Navitrack™ System - Total Hip Replacement CT-Free

ORTHOsoft Inc. Applicant: 75 Queen Street, suite 3300 Montreal, Quebec Canada, H3C 2N6 Tel.: 514 861 4074 Fax: 514 866 2197

Contact Person: Christopher McLean

Date Summary Prepared: September 19, 2003

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

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

Predicate Device:

Navitrack System™ -- Total Hip Replacement CT-Free Cup, from Orthosoft Inc. 510(k) #K030827

Device Description:

Identically as in the predicate, the Navitrack™ System – Total Hip Replacement CT-Free device consists of a software-driven workstation, an optical tracking system, surgical instruments, and tracking accessories, 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 intraoperatively. 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 kev anatomical references that are used clinically to align and position the THR components. The instruments are schematically represented.

The modifications to the predicate are to additionally track the femur and femoral instrumentation similarly as is done for the pelvis, in order to also assist in the placement of the THR components for the femur.

Indications for Use / Intended Use:

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

This is identical to the Navitrack System™ - Total Hip Replacement CT-Free Cup predicate.

Technological Comparisons to the Predicate:

The comparisons showed that the proposed device is substantially equivalent to the predicate, the Navitrack System - Total Hin Replacement CT-Free Cup. It is a modification to the predicate. The fundamental scientific technology of the Navitrack predicate is unchanged. It utilizes the same workstation and tracking technology. The modification consists in extending the capabilities of the predicate to also track the femur and its instrumentation in addition to the pelvis and its instrumentation in the predicate. Similarly as for the pelvis in the predicate, it employs the same method of having the user identify and digitize key landmarks from which the system determines femoral alignment axes relative to which the user can verify the placement of the femoral THR components. The software was correspondingly modified to handle the added capabilities, and the instrument set extended to include femoral instrumentation.

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 in depicting the positioning of the femoral THR component was adequate for its intended use.

Conclusion:

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