2. Sample Size Used for the Test Set and Data Provenance:
The document focuses on "Non-Clinical Bench Testing" for the device, which typically involves testing of the physical device components and its performance characteristics in a controlled environment. It does not mention specific 'test sets' in the context of clinical images or patient data. Therefore, information regarding sample size used for a test set (e.g., number of cases/images) and data provenance (country of origin, retrospective/prospective) is not provided as it is not applicable to the type of testing described (bench testing on the physical device).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
This information is not provided and is not applicable, as the evaluation described is non-clinical bench testing of a physical medical device (fiberscope), not an AI or diagnostic software based on image interpretation by experts.
4. Adjudication Method:
This information is not provided and is not applicable for the same reason mentioned in point 3.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and if so, what was the effect size of how much human readers improve with AI vs without AI assistance:
An MRMC comparative effectiveness study was not done. The device is a RHINO-LARYNGOFIBERSCOPE, a physical medical device for visualization, not an AI or software intended to assist human readers in interpretation or diagnosis.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
A standalone performance study was not done. This refers to an algorithm's performance without human-in-the-loop, which is relevant for AI/software devices. The device in question is a hardware endoscopic tool.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for the performance criteria in this submission is established through objective measurements and assessments against specified engineering and safety standards. For example:
- Thermal Safety: Adherence to temperature limits set by IEC 60601-2-18.
- Photobiological Safety: Adherence to light emission limits set by IEC 62471.
- Imaging Parameters (Resolution, Field of View, Depth of Field, Color Performance, Image Intensity Uniformity): Measured values are compared against design specifications and predicate device performance to ensure similarity and adequate functionality.
- Biocompatibility: Results of laboratory tests (e.g., cytotoxicity, irritation, sensitization) are compared against established biological evaluation criteria in ISO 10993 standards.
- Sterilization and Reprocessing: Demonstrated efficacy of cleaning/disinfection/sterilization methods through validated protocols according to FDA guidance and ISO 11135.
8. The Sample Size for the Training Set:
This information is not provided and is not applicable for this physical medical device. Training sets are relevant for machine learning algorithms, which this device does not utilize (it "does not contain any software").
9. How the Ground Truth for the Training Set was Established:
This information is not provided and is not applicable for the same reason mentioned in point 8.
§ 874.4760 Nasopharyngoscope (flexible or rigid) and accessories.
(a)
Identification. A nasopharyngoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the nasopharyngoscope and is intended to examine or treat the nasal cavity and nasal pharynx. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel and flexible plastic. This generic type of device includes the antroscope, nasopharyngolaryngoscope, nasosinuscope, nasoscope, postrhinoscope, rhinoscope, salpingoscope, flexible foreign body claw, flexible biopsy forceps, rigid biopsy curette, flexible biospy brush, rigid biopsy forceps and flexible biopsy curette, but excludes the fiberoptic light source and carrier.(b)
