No.
The device description and the provided information do not mention the use of AI, DNN, or ML models for any of its functionalities. The software features described are typical image processing, visualization, and navigation tools.
No.
The device assists in diagnostic and interventional procedures by providing planning and guidance, but it does not directly treat or alter a disease state itself.
No
The "Intended Use / Indications for Use" section explicitly states, "The software is not intended for diagnosis." While it assists in diagnostic procedures (like biopsies), it does not perform the diagnosis itself.
No
The device is not a software-only medical device because the device description explicitly lists several hardware components as part of the UroNav 4 System, including an "Electromagnetic Measurement System (EMMS)" with a Field Generator and System Control Unit, a "System Unit" with a CPU, monitor, medical-grade power supply, and mobile cart, and a "Field Generator Stand." While it uses software extensively for image processing and guidance, it is deeply integrated with and relies on these specific hardware components for its primary function of stereotaxic guidance and tracking.
No
The device is described as assisting clinicians with planning and guidance for interventional and/or diagnostic procedures, primarily through image fusion, visualization, and navigation. It is not intended for diagnosis and does not perform in vitro examinations of specimens derived from the human body.
N/A
Intended Use / Indications for Use
UroNav is a stereotaxic medical device intended to assist the clinician with planning and guidance for clinical, interventional and/or diagnostic procedures for biopsy and/or soft tissue ablation. It provides 2D and 3D visualization of Ultrasound (U/S) images and the ability to fuse and register these images with those from other imaging modalities such as Magnetic Resonance (MR). It also provides the ability to display a simulated image of a tracked insertion tool such as a biopsy needle, guidewire, grid plate or probe on a computer monitor screen that shows images of the target organ and the current and the projected future path of the interventional instrument taking into account patient movement. Other software features include patient data management, multi-planar reconstruction, segmentation, image measurements and 2D/3D image registration. UroNav is indicated for medical conditions that require interventional and/or diagnostic procedures of the prostate gland. The software is not intended for diagnosis. The software is not intended to predict ablation volumes or predict ablation success.

Device Description
The system assists physicians in guiding interventional instruments to pre-defined targets, which may be identified pre-procedurally or intra-procedurally using imaging data or relative to a designated position on the patient.
As an image fusion system, UroNav combines pre-procedural imaging, such as Magnetic Resonance Imaging (MRI), with real-time intra-procedural imaging from ultrasound (US) systems. This fusion capability enables precise localization of areas of interest detected in one imaging modality and maps them onto another. The system also facilitates spatial registration between two-dimensional (2D) and three-dimensional (3D) imaging datasets and between imaging data and physical patient space.
The UroNav 4 System includes the following components:
- Electromagnetic Measurement System (EMMS): Comprising a Field Generator, System Control Unit, and System Interface Unit(s) for electromagnetic tracking.
- System Unit: Incorporating a central processing unit (CPU), monitor, medical-grade power supply, mobile cart, and UroNav software.
- Field Generator Stand: Ensuring stability for electromagnetic tracking during procedures.
- Software Features: Patient data management, multiplanar reconstruction, segmentation, image measurement tools, and 3D image registration capabilities.
- Compatible Devices: Compatible with commercially available ultrasound machines, probes, needle guides, biopsy devices, and applicators.
The system reconstructs 3D ultrasound images from live 2D video streams connected to ultrasound systems. Clinicians can select targets and navigate instruments with precision through its interactive interface, which features a keyboard, mouse, and visual display. The UroNav system supports diverse clinical environments, such as hospital operating rooms, outpatient surgery centers, ultrasound suites, and procedure rooms.
The UroNav 4 design ensures compatibility with existing clinical workflows by utilizing commercially available ultrasound machines and accessories.
Additional software functionalities include patient data management, multiplanar reconstruction of images, segmentation tools for enhanced visualization, image measurements, and 3D image registration.
The UroNav 4 System is intended to aid physicians in performing minimally invasive diagnostic and therapeutic procedures by providing real-time image-guided navigation. It is not intended to replace physician judgment.

(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)

UroNav 4 is as safe and effective as its predicate device. Both devices have similar indications for use, technological characteristics, and principles of operation. The minor technological differences between the UroNav and its predicate device raise no new safety or effectiveness issues.
The predicate UroNav System was initially marketed for the placement of fiducial markers. Subsequently, these indications were removed and will not be included in the indications for use of UroNav 4. All other indication for use remain unchanged
The UroNav 4 has the same fundamental technological characteristics as the predicate. A summary of features is as follows:
- Multi-Modality Support: Enables integration of different imaging modalities for comprehensive visualization
- Image 2D/3D Review: Provides capability to review both 2D and 3D images
- 3D Rendering View: Offers three-dimensional visualization of anatomical structures
