Intended Use
The NeuroMate Stereotactic System is intended to be used in a stereotactic neurosuroical operating room for the spatial positioning and onlentation of an instrument holder or tool guide to be used by the surgeon to manually guide standard neurosurgical instruments. The NeuroMate Stereotactic System, the BRW Stereotactic System and the Compass Stereotactic System are intended for the sterectactic spatial positioning and onlentation of an instrument or tool guide to be used by a surgeon to manually guide standard neurosurgical instruments.
Device Description
The NeuroMate Stereotactic System is a computer controlled image-quided electromechanical multijointed arm. NeuroMate is intended to be used in a stereotactic neurosuroical operating room for the spatial positioning and onlentation of an instrument holder or tool guide to be used by the surgeon to manually guide standard neurosurgical instruments (Figure 1). NeuroMate assists the surgeon in its operating tasks by providing a stable, accurate, and reproducible mechanical guidance for surgical instruments, while not directly entering in contact with the patient's head. The instrument holder's sterectactic soatial positioning and orientation are determined by the neurosurgeon using an "external" (i.e., not provided by IMMI Inc.) imaging software for stereotactic planning and specific to the intended clinical application. The NeuroMate Stereotactic System acts like a motorized stereotactic frame driven by the external imaging software supported by a PC or a computer workstation providing visualization of anatomical structures and brain targets specific for the intended application (e.g., 3-D image databases from CT, MR, DSA, PET, SPECT), Following a carefully prepared stereotactic treatment plan, at the neurosumeon request. the NeuroMate Stereotactic System slowly moves and subsequently nointains an instrument holder proximal to the patient's head: NeuroMate automatically and accurately insure the correct stereotactic angular and spatial positioning of surgical instruments, thereby reducing potential human errors. During most of the duration of a neurosurgical procedure, NeuroMate is motionless and the instrument holder rigidly holds the surgical instrument chosen by the neurosurgeon prior to initiating stereotactic surgery. Only when changing spatial position and/or orientation does NeuroMate actually move. Finally, NeuroMate must be used in conjunction with a stereotactic head ring. The device operates from a 110V supply, with all of its structure grounded; the device is equipped with a double-insulation 110V/220V transformer. Its main components are: - electronic and PC circuit boards powered by switching power supplies: . - an electromechanical 5-axis multiliointed arm displaced by 24V DC motors: . - a RS-232 computer interface enabling communications with external 4 computers or workstations which operate the external imaging software driving the NeuroMate Stereotactic System. The NeuroMate Stereotactic System's controller has been specifically developed for surgical applications. It includes several functions at the mechanical and software levels, which, in case of dysfunction, quarantee the patient safety and the medical staff safety. NeuroMate Stereotactic System's controller is a "distributed controller" comprising the following elements: - an axis controller for each joint: . - a main controller module coordinating NeuroMate's motion; it performs the . necessary transformations between the Cartesian space and joint space; - a field bus linking the main controller to the axis controllers; . - a supervisor module performing all functions related to user interface, and . generating the motion orders for the NeuroMate Stereotactic System to navigate in Cartesian space.

No
The description focuses on the device being a computer-controlled, image-guided electromechanical arm for spatial positioning based on external imaging software and surgeon input. There is no mention of AI, ML, training data, or algorithms that learn or adapt.

No.
The device is a Stereotactic System that assists the surgeon in spatial positioning and orientation of surgical instruments, but does not directly deliver therapy itself or make contact with the patient's head for therapeutic purposes.

No
The device is described as a system for spatial positioning and orientation of surgical instruments in neurosurgery, assisting the surgeon in guiding instruments. It does not perform any diagnostic function.

No

The device description explicitly states it is an "electromechanical multijointed arm" with "24V DC motors" and other hardware components, clearly indicating it is not software-only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
  • NeuroMate's Function: The NeuroMate Stereotactic System is a surgical guidance system. It assists the surgeon in positioning and orienting surgical instruments during neurosurgical procedures. It does not analyze biological specimens.
  • Intended Use: The intended use clearly states its purpose is for "spatial positioning and orientation of an instrument holder or tool guide to be used by the surgeon to manually guide standard neurosurgical instruments." This is a surgical assistance function, not an in vitro diagnostic function.
  • Device Description: The description details a robotic arm that positions surgical instruments based on imaging data. It does not mention any components or processes related to analyzing biological samples.

Therefore, the NeuroMate Stereotactic System falls under the category of a surgical device or a medical device for surgical guidance, not an In Vitro Diagnostic.

Description of the test set, sample size, data source, and annotation protocol

A cohort of 45 patients (16 females; 29 males) with a mean age of 42 years (range 8-75) underwent various stereotactic procedures with the assistance of NeuroMate. The procedures were as follows: biopsy (11 cases), cystemostomy (4 cases), turnoral cyst (1 case), Parkinson (17 cases), electro-encephalogram stimulation for the treatment of acute epilepsy (12 cases).
The stereotactic approaches used included single oblique, double oblique, frontal, lateral, and parietal trajectories corresponding to standard accesses around the patient's head.

Overall performances
Overall performances of the NeuroMate Stereotactic System were assessed as a result of different testing sequences designed to:

position an instrument in any required stereotactic spatial position corresponding to predetermined entry and a target points, as determined by the neurosurgeon.

A cohort of 45 patients (16 females; 29 males) with a mean age of 42 years (range 8-75) underwent various stereotactic procedures with the assistance of NeuroMate. The procedures were as follows: biopsy (11 cases), cystemostomy (4 cases), turnoral cyst (1 case), Parkinson (17 cases), electro-encephalogram stimulation for the treatment of acute epilepsy (12 cases).

The stereotactic approaches used included single oblique, double oblique, frontal, lateral, and parietal trajectories corresponding to standard accesses around the patient's head. In all cases, NeuroMate performed as intended and successfully positioned the instrument holder at the required stereotactic spatial and angular position.

As a result of these clinical tests, the benefits of using the NeuroMate Stereotactic System for the positioning of an instrument holder can be summarized as follows:

  • NeuroMate can access any part of the patient's head for single or multiple . traiectories without the mechanical limitations encountered in the use of frames;
  • the choice of optimal trajectories adapted to anatomical, functional, and surgical ● considerations is facilitated by the accessibility provided by NeuroMate;
  • NeuroMate was successful in directly positioning its instrument holder at the . appropriate stereotactic location in 75% of the cases; following readjustment judged clinically necessary by X-ray control in-situ, the requested positioning was achieved in every case (100%);
  • NeuroMate's simulation capabilities, particularly when bi-planar X-rays are . available in the Operating Room, can significantly enhance the clinical effectiveness of the instrument holder positioning: deviations between requested positioning and clinically optimal positioning were
