Intended Use
Modus Nav is intended as a planning and intraoperative guidance system to enable open and percutaneous computer assisted surgery. The system is indicated for medical conditions requiring neurosurgical cranial procedures where the use of computer assisted planning and surgery may be appropriate. The system can be used for intra-operative guidance where a reference to a rigid anatomical structure can be identified. The user should consult the "Accuracy Characterization" section of the User Manual to assess if the accuracy of the system is suitable for their needs.
Device Description
The subject device, Modus Nav, is a modified version of its predicate, BrightMatter Guide with SurfaceTrace Registration. The system is a surgical planning and image guided surgical system that enables open or percutaneous computer-assisted cranial surgery. The system uses optical 3D tracking technology to display the location and orientation of tracked (also known as navigated) surgical instruments relative to the pre-operative scan images of the patient. The system consists of a software application installed on a computer, tracked surgical instruments, and accessories to enable the tracking of those instruments. The planning functionality of the device is provided by an already cleared device called BrightMatter Plan 1.6.0 (K180394). The remaining functionality of the system can be broadly grouped into data preparation, registration and visualization of surqical tools. Data preparation and registration is performed during the initial stages of a surgical procedure and visualization of the tools is performed as needed during the surgical procedure. General use of the system as an image guided surgical tool is composed of the following key steps: - . Equipment setup - . Plan selection and data preparation - Patient registration . - . Tool localization and visualization An optical Tracking Camera provides the position and orientation of the tools with respect to the tracking origin. The navigated surgical tools are tracked using singleuse passive reflective markers (K033621) that are attached to the surgical tools prior to each surqical procedure. An external display can be used by the surgical staff if needed, given that the Tracking Camera mounted on a cart maintains a line of sight between the Cranial Reference and the Tracked Surqical Tools. Both the User Cart (also known as Navigation Cart) and Auxiliary Carts are placed outside the sterile field. The primary purpose of this 510(k) submission is to introduce new navigated tools such as the Short Pointer, Shunt Stylet, and the corresponding Calibration Device. It also introduces new software features to support the navigation of these tools, the ability to navigate with Synaptive's Trackable Suction tools, and minor workflow improvements to facilitate the surgical procedure.
More Information

No
The summary describes a traditional image-guided surgical system using optical tracking and pre-operative images. There is no mention of AI, ML, or related concepts like deep learning, neural networks, or automated image analysis beyond basic processing verified with known datasets. The focus is on tool tracking, registration, and visualization.

No.
The device is a planning and intraoperative guidance system, which assists in surgery by tracking instruments and visualizing them relative to patient images. It does not directly provide therapy or treatment to the patient.

No

Explanation: The device is described as a "planning and intraoperative guidance system" for computer-assisted surgery, which displays the location and orientation of surgical instruments relative to pre-operative scan images. Its purpose is to guide surgical procedures, not to diagnose medical conditions.

No

The device description explicitly states that the system consists of a software application installed on a computer, tracked surgical instruments, and accessories to enable the tracking of those instruments. It also mentions an optical Tracking Camera and single-use passive reflective markers, which are hardware components.

Based on the provided text, the Modus Nav device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use clearly states that the device is a "planning and intraoperative guidance system to enable open and percutaneous computer assisted surgery." It is used during surgical procedures to guide instruments based on pre-operative images.
  • Device Description: The description reinforces this by stating it's a "surgical planning and image guided surgical system" that uses optical tracking to display the location of surgical instruments relative to patient images.
  • Lack of IVD Characteristics: An IVD is typically used to examine specimens (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The Modus Nav device does not perform any such analysis of biological specimens. It is a surgical navigation tool used in vivo (within the body) during surgery.

Therefore, the Modus Nav device falls under the category of a surgical guidance system, not an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Nonclinical performance testing was conducted including:

  • Software verification testing (system, sub-system, functional block, and compatibility testing)
  • Testing of resolved anomalies
  • Algorithm pipeline verification: Automated performance verification of the core data processing facility of the software (known as 'algorithm pipeline'). Uses known data sets and expert review of output generated by the pipeline at various stages of processing. Performance verified using known data sets or 'truth data sets' to evaluate image processing pipeline and its outputs.
  • System Requirements Verification: Biocompatibility, Cleaning Validation, Sterilization Validation, Medical Electrical System Safety, Electromagnetic Compatibility
  • System Validation: User acceptance testing by intended user group in a simulated use environment; Human Factors Validation.
  • Accuracy Characterization: System accuracy was characterized using an accuracy measurement phantom of similar volume to an adult head. The values of the ground truth data from the accuracy phantom were obtained using a Coordinate Measurement Machine (CMM). Testing was conducted with all tracked tools calculating positional and angular error for both registration methods: Surface Trace Registration and Touch Point Registration. Testing confirmed that the Modus Nav system is accurate to within 2 mm and 2 degrees of the physical tip of the tracked tool. This is equivalent to the predicate device.
  • Latency Testing: The video latency of the subject device and the predicate device were compared and deemed to be equivalent.

Clinical testing was not considered necessary as this technology is not new.

Data preparation and registration is performed during the initial stages of a surgical procedure and visualization of the tools is performed as needed during the surgical procedure.

General use of the system as an image guided surgical tool is composed of the following key steps:

  • . Equipment setup
  • . Plan selection and data preparation
  • Patient registration .
  • . Tool localization and visualization

An optical Tracking Camera provides the position and orientation of the tools with respect to the tracking origin.

devices is to track surgical instruments using an optical 3D tracking system and to show the location and orientation of these instruments relative to the pre-operative scan images of the patient during cranial procedures. The primary difference between Modus Nav and the predicate device is enhanced functionality through the introduction of new hardware involving tracked instruments, and minor workflow improvements.

Main advantages compared to the predicate device are:

  • . Minor improvements to usability introduced as a result of user acceptance testing, human factors testing and field feedback.
  • . Ability to track new instrumentation for enhanced functionality.

There are no known disadvantages.

Modus Nav remains substantially unchanged from the predicate with respect to its intended use and performance claims.

The Biocompatibility test results indicate that Modus Nav can be considered safe and suitable for the intended use and is as safe and effective as the predicate device.

The following performance testing was also conducted on Modus Nav:

  • Accuracy Characterization: .
    System accuracy was characterized using an accuracy measurement phantom of similar volume to an adult head. The values of the ground truth data from the accuracy phantom were obtained using a Coordinate Measurement Machine (CMM). Testing was conducted with all tracked tools calculating positional and angular error for both registration methods: Surface Trace Registration and Touch Point Registration. Testing confirmed that the Modus Nav system is accurate to within 2 mm and 2 degrees of the physical tip of the tracked tool. This is equivalent to the predicate device.

  • . Latency Testing:
    The video latency of the subject device and the predicate device were compared and deemed to be equivalent.

All nonclinical testing described in this section successfully passed, demonstrating that the Modus Nav system is safe and effective for its intended use and substantially equivalent to its predicate device.

Clinical Testing

This technology is not new; therefore, a clinical study was not considered necessary prior to release. The substantial equivalence of the device is supported by the nonclinical testing.

Conclusion

Modus Nav has been shown through comparison and performance testing to be substantially equivalent to the identified predicate device. Any technological differences do not raise new questions of safety and effectiveness.
