Intended Use

Stereotactic spatial positioning and orientation of an instrument holder or tool guide to be used by a surgeon to manually guide standard neurosurgical instruments.

Device Story

Neuromate Frameless Gen II is a computer-controlled, electromechanical, multi-jointed robotic arm used in operating rooms by neurosurgeons. It provides spatial positioning and orientation for neurosurgical instrument holders. Input consists of preoperative 3D imaging data processed via VoXim software; registration is performed using an ultrasound system. The surgeon defines the tool, trajectory, point of access, and orientation on the workstation; the robot then positions the tool holder accordingly. The device ensures stability during manual insertion of instruments by the surgeon. It supports both frame-based (mechanical registration) and frameless (ultrasound registration) modes. Benefits include precise, stable guidance for standard neurosurgical instruments, potentially improving procedural accuracy.

Clinical Evidence

No clinical data submitted. Bench and performance testing only. Device found compliant with IEC 60601-1 (electrical safety) and IEC 60601-1-2 (electromagnetic compatibility).

Technological Characteristics

Electromechanical multi-jointed arm with 5 degrees of freedom. Components: motors, planetary/gear reducers, worm-wheel adjustment system. Absolute digital encoders. Connectivity: workstation-based. Software: VoXim neuromate 6.4. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-4, IEC 62366, ISO 14971, IEC 62304, DICOM 3, ISO 17665-1.

Indications for Use

Indicated for neurosurgeons performing stereotactic spatial positioning and orientation of an instrument holder or tool guide to manually guide standard neurosurgical instruments during neurological surgery on the head.

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.

#### 3. PREDICATE DEVICE(s):

K991081 - Frameless Neuromate - Integrated Surgical Systems Inc

#### DEVICE DESCRIPTION: 4.

A stereotactic system with an electromechanical, multi jointed arm for spatial positioning and orientation of an instrument holder or tool guide. Guidance is based on a preoperative plan developed with three-dimensional imaging software and utilizes ultrasonic registration. The system is intended for use by neurosurgeons to guide standard neurosurgical instruments.

#### 5. INTENDED USE:

Stereotactic spatial positioning and orientation of an instrument holder or tool guide to be used by a surgeon to manually guide standard neurosurgical instruments.

#### 6. COMPARISON TO PREDICATE DEVICE:

## 6.1 Similarities

The neuromate system is a technical update of the cleared Frameless NeuroMate. It has the same intend and is similar in all the following respects:

- the patient benefits .
- the architecture of the product .
- the materials and components used .
- . the construction and method of manufacture
- . the embedded software
- . the planning and imaging software
- the operational modes offered ●
- . the attachments used

## 6.2 Differences

The only areas of difference between the neuromate and the cleared Frameless NeuroMate are:

- a. The new neuromate system is type BF applied part while the cleared Frameless NeuroMate is type B applied part.
- Note: The terms "Type BF applied part" and "Type B applied part" are used in the IEC60601-1 standard (Medical electrical equipment - Part 1: General requirements for basic safety and essential performance) to define the level of electrical isolation of an electrical medical equipment that has a part(s) in contact with a patient under normal use. The electrical isolation is between the patient and an external electrical source. In the IEC60601-1 standard, a "Type BF applied part" has a higher degree of electrical isolation compared to a "Type B applied part".
- b. The neuromate system uses absolute digital encoders to control the position of the axis of the robot arm of the system while the cleared Frameless NeuroMate uses analogical ones.
- c. The image-feedback sensor has been removed from the standard tool-holder, thereby removing the image-feedback functionality of the system

## 6.3 Conclusion

## Except for the above stated changes, the proposed Neuromate is identical in design, intended use, construction and operation to the predicate K991081.

The itemised comparison between the device and its predicate is provided in paragraph 10 (Substantial Equivalence Summary) of this document.

{2}------------------------------------------------

## 7. NONCLINICAL DATA:

Bench and performance testing showed that neuromate performed as designed and intended. The neuromate was tested to and found compliant with the requirements of IEC 60601-1 and IEC 60601-1-2.

Software was developed in compliance with FDA software guidance and IEC 62304.

#### CLINICAL DATA: 8.

No clinical data are submitted.

#### CONCLUSIONS DRAWN FROM TESTING: 9.
Øi

The testing showed that the neuromate performs as designed and intended, and is equivalent in design and performance to the predicate device.
