Explanation: The device is described as a "user-controlled positioning system intended to assist in the planning and advancement of an instrument during Computed Tomography (CT) guided percutaneous procedures," which indicates it is a therapeutic/surgical assistance device, not a diagnostic one. It helps with instrument placement, not with diagnosing a condition.
No
The device description explicitly lists hardware components like a robot positioning unit, insertion module assembly, control unit, central computer, and monitor workstation, indicating it is not software-only.
Based on the provided information, the XACT ACE Robotic System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- XACT ACE Robotic System's Function: The XACT ACE Robotic System is a surgical robotic system designed to assist physicians in performing percutaneous procedures under CT guidance. Its primary function is to help with trajectory planning and instrument positioning within the patient's body.
- Lack of Specimen Analysis: The description does not mention the system analyzing any biological specimens. It focuses on guiding instruments for procedures performed directly on the patient.
Therefore, the XACT ACE Robotic System falls under the category of surgical or interventional devices, not IVDs.

Summary of Performance Studies
Performance testing included compatibility testing between the instruments (ablation probes), the Instrument Insertion Kit securing them and the robotic system. According to a predefined protocol -"Needle Properties", the physical characteristics of each probe were first measured including their "Max. Curvature", which defines the maximum, non-vertical force that can be applied without deforming the probe. Then, the robotic system was used to steer each of the probes to a variety of targets while closely monitoring the performance of the Instrument Insertion Kits and the overall accuracy in reaching the targets. This verification test demonstrated that Instrument Insertion Kit efficiently secures the probes and advance them to the target without any physical damage to the probes. Furthermore, all relevant physical characteristics were adequately measured and configured in the robotic system allowing steering to the targets while meeting performance specifications. Then, the XACT ACE Robotic System was validated in a simulated clinical environment, in a CT suite using a specific phantom. This test was performed to verify it steers the compatible listed ablation probes to a variety of targets ("organs" and target depths), while meeting similar performance characteristics (tip-to-target average accuracy) compared to biopsy introducers. All trajectories included several checkpoints and performance was evaluated based on CT images obtained during the procedures. Test results demonstrated that the device meets all of its performance characteristics with no changes to the clinical workflow.

procedures. The system is used for trajectory planning and is intended to assist the physician in positioning of an instrument, such as a needle, where CT imaging is used for target trajectory planning and intraoperative tracking.
Device Description
The XACT ACE Robotic System is a user-controlled positioning system intended to assist in the planning and advancement of instruments during Computed Tomography (CT) guided percutaneous procedures. The system is used for trajectory planning based on CT images and is intended to assist the physician in positioning of an instrument, such as a needle, and reviewing instrument position during advancement to the target. The system quides (i.e., positions and steers) the instrument according to a predefined trajectory. The physician controls advancement of the instrument along the trajectory using a foot pedal. The system also allows for monitoring of motion associated with respiration during the procedure.
The XACT ACE Robotic System comprises the following main components:
- XACT ACE Robot which is placed on the patient and includes the robot positioning unit & the insertion module assembly
- XACT ACE Console which includes a Control Unit, central computer (in the Control Unit) and monitor workstation for user trajectory planning, user interface and review of instrument position.
Technological Characteristics
The XACT ACE Robotic System allows for planning of percutaneous CT-quided procedures and tracking and positioning of the instrument during the procedure.
Both the XACT ACE Robotic System and its previously cleared predicate are designed and intended for planning and positioning of instruments for percutaneous intervention under imaging guidance of CT scanners. The systems position the instrument according to a predefined trajectory following a registration process between the device's coordinate system and real-time CT images. The user advances the instrument through several checkpoints using a foot pedal.
Both systems are comprised of the same components and accessories. Further, the system software for the XACT ACE Robotic System does not introduce any new features or significant changes to existing features. Although there are minor differences between the subject and predicate device, namely supporting use of the device in the positioning of ablation probes, these differences do not raise new or different questions of safety or efficacy.
Performance Data
The performance testing included compatibility testing between the instruments (ablation probes), the Instrument Insertion Kit securing them and the robotic system. According to a predefined protocol -"Needle Properties", the physical characteristics of each probe were first measured including their "Max. Curvature", which defines the maximum, non-vertical force that can be applied without deforming the probe. Then, the robotic system was used to steer each of the probes to a variety of targets while closely monitoring the performance of the Instrument Insertion Kits and the overall accuracy in reaching the targets. This verification test demonstrated that Instrument Insertion Kit

efficiently secures the probes and advance them to the target without any physical damage to the probes. Furthermore, all relevant physical characteristics were adequately measured and configured in the robotic system allowing steering to the targets while meeting performance specifications.
Then, the XACT ACE Robotic System was validated in a simulated clinical environment, in a CT suite using a specific phantom. This test was performed to verify it steers the compatible listed ablation probes to a variety of targets ("organs" and target depths), while meeting similar performance characteristics (tip-to-target average accuracy) compared to biopsy introducers. All trajectories included several checkpoints and performance was evaluated based on CT images obtained during the procedures. Test results demonstrated that the device meets all of its performance characteristics with no changes to the clinical workflow.
Conclusions
The XACT ACE Robotic System has the same intended uses and indications for use, technological characteristics and principles of operation as its predicate device. The limited differences in enabling support of ablation probes in addition to biopsy introducers do not affect the safety or effectiveness of the device. Performance tests demonstrates that the XACT ACE Robotic System is as safe and effective as the predicate device. Thus, the XACT ACE Robotic System is substantially equivalent.
