Indications for Use

The Fiagon Navigation System is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. The Fiagon Navigation System is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure in the field of ENT surgery, such as the paranasal sinuses, mastoid anatomy, can be identified relative to a CT or MR based model of the anatomy. Example procedures include, but are not limited to: ENT Procedures; Transphenoidal access procedures. Intranasal procedures. Sinus procedures, such as Maxillary antrostomies, Ethmoidectomies, Sphenoidotomies/Sphenoid explorations, Turbinate resections, and Frontal sinusotomies. ENT related anterior skull base procedures

Device Story

Fiagon Navigation System provides real-time intraoperative visualization of surgical instruments relative to patient anatomy. System utilizes electromagnetic tracking; field generator creates electromagnetic field; localizer elements integrated into patient reference localizer and surgical instruments (e.g., FlexPointer, FinePointer) track position within field. Preoperative DICOM images (CT, CBCT, MR) imported via CD, USB, or LAN. Registration procedure aligns intraoperative patient position with preoperative scan via fiducial markers, anatomical landmarks, or surface matching. Navigation unit processes spatial data; displays instrument position superimposed on image data at 15-45 Hz update rate. Used in OR by surgeons to guide ENT procedures; provides visual feedback for precise anatomical localization. Benefits include improved surgical accuracy and navigation in complex ENT anatomy.

Clinical Evidence

Bench testing only. Evaluated device precision, accuracy, and electromagnetic field distortion detection. Mean bench accuracy of 0.9 mm (SD 0.34 mm). Reported mean clinical accuracy of 1.79 mm (SD 0.4 mm). Results demonstrate performance within range of predicate devices (1.64-2.8 mm clinical accuracy).

Technological Characteristics

Electromagnetic tracking system. Components: navigation unit, field generator (headrest), patient reference localizer, and instruments (stainless steel, medical grade adhesive). Connectivity via LAN/USB/CD. Software-based navigation. Operates on 110-240Vac. No specific algorithm architecture stated; uses spatial coordinate transformation for image-to-patient registration.

Indications for Use

Indicated for patients undergoing ENT stereotactic surgery where rigid anatomical structures (e.g., paranasal sinuses, mastoid) can be referenced to CT/MR image models. Applicable for open or percutaneous procedures including transphenoidal, intranasal, sinus, and anterior skull base surgeries.

#### 5. Device Description

The Fiagon Navigation System displays the position instruments in preoperative scans (e.g., CT, MRI, fluoroscopy) utilizing electromagnetic tracking technology. The position of the instrument with integrated sensor and the patient equipped with localizers are localized within an electromagnetic field generated by a field generator. The principle of navigation is based on electromagnetic spatial measuring of localizer element in a generated electromagnetic field.

The display of navigation information requires an image-to-patient registration procedure. During registration procedure, the navigation system determines the coordinate transformation between the intraoperative position of the patient and the position of the preoperative scan by fiducial marker, anatomical landmark or surface matching,

Thereafter the spatial position of the instrument is displayed superimposed to the image data. The navigation information is updated with a rate of 15 to 45 Hz.

### Device Design

The components of the navigation system are

- 1. Navigation unit with Navigation software. It has interfaces for screen, mouse and the components 2 - 4.
- 2. Navigation sensor (Headrest with field generator)
- 3. Navigation instrument,
- 4. Patient reference localizer (with fixation material) :

The navigation unit, is connected to a medical monitor. The unit runs the navigation software. Preoperative radiological images of the patient (DICOM CT, CBCT, MR) is imported to the system by means of CD-ROM, USB storage media or LAN network and displayed in appropriate way (defined by the software)

The navigation unit compromises as well the spatial measuring device electronics. This has connections to the field generating device (navigation sensor), the patient localizer and the navigation instrument.

Patient reference localizer and navigation instrument are tracked within the generated field by localizer elements integrated in the devices.

The patient reference localizer is fixed to the patients anatomy and references it, while the instrument is tracked in relation to the patient localizer and thus to the patient's anatomy.

#### 6. Intended Use

The Fiagon Navigation System is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. The Fiagon Navigation System is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure in the field of ENT surgery, such as the paranasal sinuses, mastoid anatomy, can be identified relative to a CT or MR based model of the anatomy.

Example procedures include, but are not limited to:

ENT Procedures; Transphenoidal access procedures. Intranasal procedures. Sinus procedures, such as Maxillary antrostomies, Ethmoidectomies, Sphenoidotomies/Sphenoid explorations, Turbinate resections, and Frontal sinusotomies. ENT related anterior skull base procedures

### 7. Comparison of Technological Characteristics

The substantial equivalence of the Fiagon Navigation System to the predicates is shown by similarity in intended use, indications for use, materials, and performance. The Fiagon Navigation System and its predicates utilize:

- . Electromagnetic tracking technology for navigation
- Anatomical or fiducial reference points on the patient's anatomy for intraoperative . registration to the image-based model of the anatomy
- . CT or MR image sets as reference images for the image-based model

The primary difference between the Fiagon Navigation System and its predicates is that the Fiagon System includes the option of navigating flexible-tip instruments by mounting the instrument localizer in the tip of the instrument. Since tracking a localizer in the tip of the instrument provides similar navigation accuracy as tracking the tip of a rigid instrument via a localizer mounted to the instrument handle, this difference does not raise new issues of safety and effectiveness.

{4}------------------------------------------------

#### 8. Performance Data

Testing was performed in order to determine device precision and accuracy and the electromagnetic field distortion detection mechanism. The following nonclinical tests were performed to determine substantial equivalence:

Bench testing was conducted to determine the device accuracy and the performance of the electromagnetic field distortion mechanism.

A mean bench accuracy of 0.9 mm (Standard deviation 0.34 mm) was measured which compares to the values 0.8 mm to 1.0 mm reported for the predicate devices.

Results showed that the device detected field distortions under normal conditions before the induced error became larger than 0.9 mm which compares to a value of 1.0 mm reported for the predicate device.

Reported mean clinical accuracy was 1.79 mm (Standard deviation 0.4 mm) which compares to the reported mean clinical accuracy of the predicate devices in the range of 1.64 mm to 2.8 mm.

The results supports the claim of substantial equivalence to the predicate devices.

#### 9. Conclusion

Based on the indications for use, technological characteristics, performance testing, and comparison to the predicates, the Fiagon Navigation System has been shown to be substantially equivalent to the predicate devices identified in this submission, and does not present any new issues of safety or effectiveness.
