Intended Use

The Brainlab Elements Trajectory Planning software is intra- and postoperative image-based planning and review of either open or minimally invasive neurosurgical and neurological procedures. Its use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate for the placement of instruments/devices and where the position of the instrument/device can be identified relative to images of the anatomy. This includes, but is not limited to, the following cranial procedures (including frame-based stereotaxy and frame alternative-based stereotaxy): - Catheter placement - Depth electrode placement (SEEG procedures) - Lead placement and detection (DBS procedures) - Probe placement - Cranial biopsies

Device Story

Software for pre-, intra-, and postoperative image-based planning/review of neurosurgical procedures. Inputs: DICOM anatomical images (axial, coronal, sagittal). Processing: Co-registration, segmentation, trajectory definition, and automatic lead detection in post-operative CT images. Outputs: DICOM data, coordinates, and measurements (e.g., stereotactic arc settings). Used in clinical settings by neurosurgeons/clinicians via touchscreen, mouse, or keyboard. Facilitates surgical planning by visualizing anatomy and instrument paths; assists in DBS lead localization. Benefits: Improved accuracy for stereotactic instrument placement; supports frame-based and frame-alternative procedures.

Clinical Evidence

Clinical claims supported by literature review and post-market data. Software verification testing confirmed all specifications met acceptance criteria. Summative usability testing concluded no critical errors leading to hazardous situations for patients or users.

Technological Characteristics

Software-based medical device for image processing and planning. Operates on standard hardware (laptop/workstation) with touchscreen/mouse/keyboard input. Supports DICOM data import/export via network or removable media. Features include multi-modal image co-registration, segmentation, and automated lead detection. No specific hardware materials or sterilization methods applicable as it is a software-only device.

Indications for Use

Indicated for patients undergoing neurosurgical or neurological procedures where stereotactic surgery is appropriate for instrument/device placement, including catheter, depth electrode (SEEG), lead (DBS), probe placement, and cranial biopsies.

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.

## 1. Indication for Use

The Brainlab Elements Trajectory Planning software is intended for pre-, intra- and postoperative image-based planning and review of either open or minimally invasive neurosurgical and neurological procedures.

Its use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate for the placement of instruments/devices and where the position of the instrument/ device can be identified relative to images of the anatomy.

This includes, but is not limited to, the following Cranial procedures (including frame-based

stereotaxy and frame alternative-based stereotaxy):

- Catheter placement
- · Depth electrode placement (SEEG procedures)
- · Lead placement and detection (DBS procedures)
- Probe placement
- Cranial biopsies

## 2. Device Description

Trajectory planning is a software device which is used for the processing and viewing of anatomical images (for example: axial, coronal and sagittal reconstructions, etc.) and corresponding planning contents (for example: co registrations, segmentations, trajectories, etc.). The device is also used for the creation of coordinates and measurements that can be used as input data for surgical intervention (e.g. stereotactic arc settings).

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

The software is used in three different configurations:

- 1. Trajectory (Element): allows the creation of trajectories
- 2. Stereotaxy (Element); allows the creation of trajectories and supports also frame based procedures
- Lead Localization (Element): allows the creation of trajectories and automatic detection of ဒေ.
က leads in post-operative images

The software takes (DICOM) data as input and provides (DICOM) data as outputs. This data can be transferred by removable memory devices like USB sticks or via network.

The user interaction can be done with a touchscreen and/or with a mouse, optionally combined with a keyboard on a laptop which fulfill minimum requirements.

#### 3. Substantial Equivalence

The Subject Device is similar to the predicate device in terms of:

- Support of frame based procedures including stereotactic localization and arc settings । calculation
- -Trajectory planning on multi-modal co-reqistration images
- Multiple views for reconstructed medical images -
- -Visualization for supplemental information like segmented structure and fiber tracts
- Definition and usage of AC/PC coordinate system for Trajectory Planning -

The Subiect Device differs from the predicate device in terms of:

- Additional indications included for SEEG procedures, DBS procedures, Probe placement -
- -Spine and ENT indications
- Additional stereotactic hardware support (Elekta Vantage) -
- Predicate device was split into multiple medical software modules -
- -Addition of automatic lead detection in CT images
- User Interfaces -

### 4. Performance Data

#### Software Verification

Software verification testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices,"

Software verification was carried out for all the specifications and all tests met the acceptance criteria. In addition to the verification activities, the risk analysis shows that all relevant hazards have been taken into consideration, that risk control is complete and that the corresponding measures are in place.

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

# Usability

Data from the Summative Usability test concluded that there is no indication that the use of the device could lead to critical errors resulting in a hazardous situation for patient or user.

# Clinical Evaluation

Clinical claims were supported via data from literature and post market data collected.

# 5. Conclusion

The comparison of the Subject Device with the predicate device shows that the device has similar functionality, intended use, technological characteristics, and typical users as the predicate device. Verification and validation activities ensured that the design specifications are met and that the Subject Device substantially equivalent to the predicate device.
