Intended Use

The intended use of the Micromate™ device is to function as a remote-operated positioning and guidance system during interventional procedures. Positioning is done in a remote controlled manner; planning of the position/angulation is done based on 2D/3D patient data (CT, cone-beam CT, fluoroscopy) by external planning software - for example using an external navigation system, or planning software coming with the used imaging device. Also, verification of the correct position and orientation of the tool prior to/during/after the intervention is done by means of these external devices. The Micromate™ system is then acting as a guideway during the manual insertion of the interventional tool - usually a needle type device, and the like- through a third-party needle guide, manufactured by Exact MM (K101689): P/N E2183 (Device Cover with 11G-14G needle guide) or P/N E2184 (Device Cover with 15G-21G needle guide). During operation, the device is covered with a sterile drape, which is part of the P/N E2183 and E2184. An additional third-party Control Unit Drape is available, also manufactured by Exact MM (K101689): P/N 11718EU (Handheld Device Cover). Applications include, but are not limited to, interventions like biopsy procedures, tumor ablation, nerve blocking, electrode placement, etc.

Device Story

Micromate™ is a remote-operated robotic positioning and guidance system for percutaneous surgical interventions. It consists of a targeting platform, handheld control unit, positioning arm, and power/network unit. The system aligns a needle guide to a surgical plan defined by external 2D/3D imaging (CT, cone-beam CT, fluoroscopy) and navigation software. The surgeon performs gross positioning manually, followed by automatic or joystick-controlled fine alignment. Once aligned, the surgeon manually advances the needle or electrode through the guide while the system maintains the trajectory. Used in clinical settings, the device is covered by sterile drapes and interfaces with third-party needle guides. It benefits patients by providing precise, stable instrument guidance during procedures like biopsies, tumor ablations, and electrode placements, reducing potential manual error while keeping the physician in control of the final surgical gesture.

Clinical Evidence

Clinical performance data was obtained using the Micromate™ system in combination with the Philips Allura Xper FD20 X-ray system. Accuracy metrics reported: 95% CI for alignment accuracy between 0.00 mm to 1.14 mm and 0.25 degrees to 1.70 degrees from the surgical plan. Average accuracy of alignment to the trajectory on Entry Point view was 0.43 ± 0.5 mm, with an average angular deviation of 0.79 ± 0.41 degrees. Mechanical accuracy in air was <1 mm (0.03 mm relative, 0.2 mm absolute).

To the right of the "i" are the words "INTERVENTIONAL" in bold, black letters, with the word "systems" in a smaller font and a lighter color below it.

The system comprises the following main components:

- . Tarqeting Platform, a robotic positioning unit that aligns to the surgical plan and holds the surgical instruments through an end-effector acting as a tool-guide adapter.
- . Control Unit, a handheld device that allows the automatic or manual control of the Targeting Platform movement and can communicate with an external planning and navigation station.
- . Positioning Arm, a multi-functional arm that is used to gross-position the Targeting Platform in such a way the trajectory is reachable.
- . Strain Relief Box, which distributes power and data through the Micromate™ system.
- . Power and Network Unit, which connects the system to power and allows an optional direct point-to-point connection to an external planning and navigation station for input of real-time navigation data.
- . Sterile Drapes for the Control Unit and Targeting Platform (this one containing also needle guides) for instrument guidance.
- . Connecting Cables
- A cart for transport and storage .

The system can be mounted to different bed/table through specific adapter accessories and all components are covered with a sterile drape during use. Third-party needle or tool guides are connected to the Targeting Platform end-effector through a customized mechanical interface that preserves the sterile barrier.

Micromate™ is not patient contacting.

- The intended use of the Micromate™ device is to function as a remote-10. Intended Use: operated positioning and quidance system during interventional procedures. Positioning is done in a remote controlled manner; planning of the position/angulation is done based on 2D/3D patient data (CT, cone-beam CT, fluoroscopy) by external planning software - for example using an external navigation system, or planning software coming with the used imaging device. Also, verification of the correct position and orientation of the tool prior
to/during/after the intervention is done by means of these external devices.

Applications include, but are not limited to, interventions like biopsy procedures, tumor ablation, nerve blocking, electrode placement, etc.

- 11. Indications for use: The Micromate™ device is a user-controlled electromechanical arm with a needle guide. It is intended to assist the surgeon in the positioning of a needle or electrode where both computed tomography (CT) and fluoroscopic imaging can be used for target trajectory planning and intraoperative tracking. The needle or electrode is then manually advanced by the surgeon. Trajectory planning is made with software that is not part of the Micromate™ device
- 12. Clinical Use: Depending on the used operating table, the user selects a specific table adapter and attaches it to the table (a Table Top Adapter for C-arm couchtops, a Standard Baseplate and respective adapters for a CT-table or Fluoro-CT table, Side-Rail Adapters for side-rails on any table). All adapters are equipped with a starburst connector, to which the multi-functional Positioning Arm is connected. The Positioning Arm is equipped with one starburst adapter at the bottom and a spoon adapter at the top, to which the Targeting Platform is connected with a counterpart. A Strain Relief Box (for power distribution and cable management) and the Control Unit for handheld remote control of the Targeting Platform are connected to a siderail. Both the Targeting Platform and the Control unit are connected to the Strain Relief Box with cables. The Strain Relief Box is then connected to a Power and Network Unit, responsible for the power and data input into the system, respectively through a power cord that is connected to the mains outlet and a network cable that can be plugged into an external planning or navigation station. An end-effector is connected to the Targeting Platform and the assembly (comprised of the Targeting Platform carrying and Endeffector and the Positioning Arm) are covered with a sterile drape. A sterile disposable needle guide is connected to the End-effector interface with the sterile drape in place. The Control Unit can optionally be covered with the respective sterile drape. The Targeting Platform is gross-positioning within the region of interest, by locking the Positioning Arm when the Targeting Platform is in the desired position. Planning of the tool position/orientation as well as validation of the correctness of the tool position must be performed with an external planning or navigation station. The Targeting Platform is remotely controlled using the Control Unit for fine positioning and to align the needle guide axis to the surgical plan. The surgical instruments are then inserted manually by the user into the needle guide and advanced to the planned target. For procedures requiring the placement of multiple instruments, each instrument can be released from the needle guide after placement and the alignment to additional planned surgical trajectories performed similarly.

- Biocompatibility: The Micromate™ is not in contact with the patient. At any time, when in 13. use, a third-party sterile drape is to be placed between the patient and the system. No biocompatibility studies were considered necessary for this device.
- 14. Performance Data: Operating conditions: 10-30°C (50-86°F), 30-70% RH, non-condensing, 0.689 bar-1.019 bar, altitude up to 3000m (9842 ft). Shipping conditions: 0-40°C (32–104°F), 20–80% RH, non-condensing, 0.689 bar–1.019 bar. Storage conditions: 0–30°C (32–86°F), 20–80% RH, non-condensing, 0.689 bar–1.019 bar. Power supply: 30VA, 100-240 VAC, 50/60 Hz.

Sterilization of the sterile accessories has been validated by Exact Medical Manufacturing (K101689), the legal manufacturer of the sterile drapes and needle quides compatible with the Micromate™.

The accuracy of the intervention is adjunct to the capabilities of the operator and depends on the resolution of the imaging device or software, among other factors. As calculated from actual clinical data, the 95% confidence interval (CI) accuracy of Micromate™ in clinical use is between 0.00 mm to 1.14 mm and 0.25 degrees to 1.70 degrees from the surgical plan. This corresponds to an average accuracy of alignment to the trajectory on Entry Point view of 0.43 ± 0.5mm, and an average angular deviation of the needle when being inserted along the trajectory of 0.79 ± 0.41 degrees. Micromate™ has no influence on the accuracy of the needle placement on target in terms of depth, as the instrument is manually delivered and advanced by the physician, under live imaging. All results were obtained in combination with the Philips Allura Xper FD20 X-ray system.

The mechanical accuracy of the Micromate™ system itself is below 1 mm (relative mechanical accuracy 0.03 mm and absolute mechanical accuracy 0.2 mm), as measured by commanding the Targeting Platform to a predetermined location in air.
