NAVIAID BALLOON GUIDED COLONOSCOPY (BGC) DEVICE
The NaviAid™ BGC device is an accessory to an endoscope and is intended to ensure positioning of a standard endoscope during endoscopy of the small and large intestine (standard endoscope-i.e., an endoscope that has an instrument channel that is at least 3.7mm diameter and is used for standard endoscopic visualization).
The NaviAid™ BGC Disposable is an on-demand disposable that is inserted through the instrument channel of the endoscope in order to ensure positioning of a standard endoscope during endoscopy of the large or small intestine (standard endoscope - i.e., an endoscope that has an instrument channel that is at least 3.7mm diameter and is used for standard endoscopic visualization). The NaviAid™ BGC system comprises a disposable balloon system and an Air Supply Unit for inflating and deflating the balloon system. The role of the BGC disposable is to facilitate advancement of a standard endoscope into the large and/or small intestine. The NaviAid™ BGC Disposable includes the BGC Balloon and the BGC inflation tube. The balloon is inflated by ambient air. The Air Supply Unit ("ASU") operates and controls the inflation and deflation of the balloon through a footpedal. The balloon is connected to a dedicated inflation tube that runs inside the instrument channel of the endoscope, and is connected at its proximal (user) end to the ASU. The BGC balloon can be advanced ahead of the endoscope tip or pulled back by pushing/pulling action on the BGC inflation tube at its proximal side, outside the patient's body. When the BGC balloon is advanced and then inflated, it functions as a distal anchor, to which the endoscope tip is advanced, and the BGC inflation tube serves as a "guide wire" that leads the endoscope as it is pushed towards the anchoring BGC balloon.
The NaviAid™ BGC device is designed as an accessory to an endoscope to facilitate its positioning in the small and large intestine. The device's performance was evaluated through a series of non-clinical tests to demonstrate its conformance to design specifications and safety requirements.

2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states "Clinical Performance Data: Not Applicable." Therefore, there was no test set involving human subjects. The performance evaluations were conducted through non-clinical, in-vitro testing. The data provenance is internal to Smart Medical Systems Ltd., Israel, as all listed test document numbers appear to be internal company documents (e.g., Doc. No. TP310001).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable, as no clinical test set with human subjects requiring expert ground truth establishment was conducted. The non-clinical tests would have been evaluated against engineering and design specifications by internal company engineers and quality assurance personnel.
4. Adjudication Method for the Test Set
Not applicable, as no clinical test set requiring adjudication was conducted.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was conducted. The document states "Clinical Performance Data: Not Applicable."
6. Standalone Performance (Algorithm Only without Human-in-the-Loop Performance)
Since this is a mechanical accessory device, the concept of "standalone (algorithm only without human-in-the-loop performance)" does not directly apply in the typical AI context. The device itself is designed as an accessory to be used with a human-operated endoscope. Its performance was evaluated in terms of its mechanical, electrical, and material properties. The non-clinical tests listed serve as the "standalone" performance evaluation of the device's technical specifications and safety attributes independent of clinical human performance outcomes.
7. Type of Ground Truth Used
For the non-clinical tests, the ground truth was established by adherence to:
- Engineering and Design Specifications: Each test (e.g., BGC Air Leakage, Component Bond Strength) would have specific quantitative or qualitative criteria defined during the device's design phase.
- International Standards: Compliance with recognized standards like IEC 60601-1, IEC 60601-1-2, IEC 60601-1-4, and ISO 10993 served as the ground truth for safety, electrical, mechanical, software, and biocompatibility aspects.
- Simulated Conditions: The "BGC In-Vitro Validation Test" implies testing in a simulated environment to assess the device's functional performance in a context mimicking its intended use.
8. Sample Size for the Training Set
Not applicable. The NaviAid™ BGC device is a mechanical accessory, not an AI or machine learning algorithm, and therefore does not have a "training set" in the conventional sense.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
