Intended Use

The GuideWire 0.6 is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. It is indicated for use with the Fiagon Navigation system using electromagnetic navigation. It 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

GuideWire 0.6 is an electromagnetically navigated, flexible surgical instrument; incorporates a sensor at the tip for tracking within a low-energy magnetic field generated by the Fiagon Navigation system. Used in ENT procedures to locate anatomical structures; provides real-time position data displayed on preoperative CT/MRI/fluoroscopy scans. Operated by surgeons to assist in precise navigation during sinus and skull base surgeries. Benefits include improved anatomical localization during minimally invasive or open procedures. Geometrically modified version of predicate instruments.

Clinical Evidence

Bench testing only. Accuracy testing performed on the device compared to the predicate; mean accuracy of 1.27 mm (SD 0.4 mm) vs 1.24 mm (SD 0.44 mm) for the predicate. Functionality and system compatibility verified.

Technological Characteristics

Electromagnetic tracking; flexible instrument with pre-calibrated sensor at tip; compatible with cannulated instruments; reusable; low-energy magnetic field sensing.

Indications for Use

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

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

#### ട്. Device Description

The Fiagon Navigation - FlexPointer 1.5 is a reusable instrument intended to be used with the Fiagon Navigation system. The instrument is an electromagnetically navigated devices that is

- a. Navigated pointing devices (maleable, sensor within the tip)
Each device incorporates a sensor device, which is tracked by the navigation system with in the low-energy magnetic field of a field generator (part of the navigation system)

The navigation software (part of the navigation system) displays the position of the instruments in preoperative scans (e.g., CT, MRI, fluoroscopy)

#### 6. Intended Use

The GuideWire 0.6 is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. It is indicated for use with the Fiagon Navigation system using electromagnetic navigation.

It 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 GuideWire 0.6 to the unmodified devices GuideWire and VenteraPointer is shown by similarity in intended use, indications for use, materials, and performance. All devices utilize:

- · Electromagnetic tracking technology for navigation included in surgical instruments
- flexible instruments enabled for image guidance
- · Instruments with tracking sensor at the instrument tip, precalibrated
- · Compatible to use in combination with verified cannulated instruments

{5}------------------------------------------------

The primary difference between the unmodified devices and the new device is geometrical change of the outer construction of the device (diameter and length). This different does not raise new issues of safety and effectiveness.

#### 8. Performance Data

Testing was performed in order to determine device precision and accuracy. The following nonclinical tests were performed to determine substantial equivalence:

A mean bench accuracy of 1.27 mm (Standard deviation 0.4 mm) was measured for the new device. which compares to the values mean 1.24 mm (Standard deviation 0.44 mm) in an identical test setup.

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

Testing was completed to ensure functionality and compatibility with the Fiagon Navigation system.

#### 9. Conclusion

Based on the indications for use, technological characteristics, performance testing, and comparison to the predicates, the GuideWire 0.6 has been shown to be substantially equivalent to the comparable devices GuideWire and VenteraPointer, and does not present any new issues of safety or effectiveness.
