No
The device description explicitly lists hardware components such as a mobile navigation platform with touch screens, a camera, a computer, and physical instruments (guide arm, aiming device, navigational pointer). While software is a key component, it is part of a larger system that includes hardware.
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 perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description of CAS-One IR clearly states its purpose is to assist in planning, navigation, and verification during CT-guided interventional procedures. It is a stereotactic accessory used to guide instruments (needles, probes) within the patient's body based on imaging data.
- Lack of Sample Analysis: There is no mention of the device analyzing biological samples or performing any tests on materials taken from the body. Its function is entirely focused on guiding instruments within the body.
Therefore, CAS-One IR falls under the category of a surgical or interventional guidance system, not an In Vitro Diagnostic device.
No
The provided input states "Control Plan Authorized (PCCP) and relevant text: Not Found," indicating no mention of PCCP authorization.
Intended Use / Indications for Use
CAS-One IR is a user controlled, stereotactic accessory intended to assist in planning, navigation and manual advancement of one or more instruments, as well as in verification of instrument position and performance during Computed Tomography (CT) guided procedures.
In planning, the desired needle configuration and performance is defined relative to the target anatomy.
In navigation, the instrument position is displayed relative to the patient and guidance for needle alignment is provided while respiratory levels are monitored.

Substantial Equivalence Discussion
Both the Subject Device and the Predicate Device have the same Intended Use. The Subject Device is an updated version of the Predicate Device. The differences between the Subject and Predicate Device are: Incremental improvements to the hardware (updated mainboard, GPU, and touchscreens on the platform; mechanical improvements to the pointer, aiming device, and quide arm), and Software Changes (update Operating System, increments, addition of segmentation functions for tumor and ablation area)
The subject device introduces seven new software functions which are considered to have the same technological characteristics as the predicate device because similar software functions are included in the predicate device.
The subject device has three different technological characteristics compared to the predicate device: Segmentation of organs and liver lesions, Instrument Detection, AblaSure® Ablation Assessment (for liver lesions). All three different technological characteristics are related to Software Functions.
Software Validation has been carried out for all functions. Specific Non-Clinical Performance Testing has been carried out for the segmentation algorithms. The instructions for use include warnings for the limitations of the segmentation algorithms.
It has been demonstrated that the technological differences do not adversely affect the safety and effectiveness of the subject device. No questions for safety and effectiveness were raised. Therefore, we can conclude that no technological differences, that may adversely affect the safety and effectiveness, have been identified between the subject and predicate device.
Conclusion - Substantial Equivalence Discussion:
The subject device is substantially equivalent to the predicate device with regard to intended use, safety, and effectiveness. This conclusion is based upon a comparison of intended use, technological characteristics, and non-clinical performance testing.
VII. PERFORMANCE DATA
The following performance data were provided in support of the substantial equivalence determination.
Biocompatibility Testing
Not Applicable. The subject device has similar material properties, and it was evaluated there is no effect to the biocompatibility properties of the subject device.
Electrical safety and electromagnetic compatibility (EMC)
The subject device was tested for electrical safety (ANSI AAMI ES60601-1) and electromagnetic compatibility (ANSI AAMI IEC 60601-1-2).
11
Mechanical and Acoustic Testing
Not Applicable to the subject device.
Software Verification and Validation Testing
Software verification and validation testing were provided to demonstrate safety and effectiveness of the subject device. Software validation and documentation was prepared according to the "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" (May 11, 2005).
This includes a hazard analysis, and the potential hazards have been classified as a moderate level of concern similar to the predicate device.
Algorithm validation
Test protocols were systematically executed to assess the performance of the algorithmic validation procedures involved comparisons with ground truth data annotated by personnel considered expert in the domain.
The segmentation algorithms of organs, hepatic veins, and lesions were validated by comparing the mean DICE coefficient with state-of-the-art algorithms. Defined acceptance criteria for mean DICE (Liver: 0.9, Tumor: 0.8, Effective Treatment Volume: 0.8, Kidney: 0.85, Lung: 0.9) and mean centerline DICE (Liver-Vessels: 0.6) were passed.
For instrument detection algorithms, the reliability was gauged by analysing the pround truth positions and the positions identified by the algorithm.
These validation efforts provide a robust foundation for asserting the accuracy and effectiveness of the algorithms in the context of their application in medical settings.
Animal Study
Animal performance testing was not required to demonstrate safety and effectiveness of the device.
Clinical Studies
Clinical testing was not required to demonstrate the safety and effectiveness of the device. This conclusion is based upon a comparison of intended use, technological characteristics, and non-clinical performance data (Software Verification and Validation Testing, and Internal Test Standards).
