Intended Use
The Single-use Flexible Rhinolaryngoscope is designed for use with Vathin Display Units, for examination of nasal cavity and upper respiratory tract. For Rhinolaryngoscope models that include a working channel and permit the use of a compatible 3rd party accessory, treatment is also possible.
Device Description
The Single-use Flexible Rhinolaryngoscope can be connected to the compatible Vathin Display Units and other accessories for examination and treatment of nasal cavity and upper respiratory tract. There are eight subject nasopharyngoscope models: RL-S1800, RL-S1801, RL-E1800, RL-E1801, RL-S1E00, RL-S1E01, RL-E1E00, RL-E1E01. The main differences between product models are in the working channel inner diameter (whether channel is present or not), outer diameter, and rotate function.
More Information

No
The summary describes a standard flexible rhinolaryngoscope and its associated display units and accessories. There is no mention of AI, ML, image processing for analysis, or any data sets for training or testing AI/ML models. The performance studies focus on biocompatibility, electrical safety, EMC, and general performance testing, not AI/ML performance metrics.

Yes
The "Intended Use / Indications for Use" section states that for models with a working channel, "treatment is also possible," indicating a therapeutic function.

Yes

The intended use explicitly states "examination of nasal cavity and upper respiratory tract", which is a diagnostic purpose. While it also mentions "treatment is also possible" with certain models, the primary and general use described is for examination, making it a diagnostic device.

No

The device description clearly describes a physical, flexible rhinolaryngoscope with different models based on physical characteristics like working channel diameter and outer diameter. It also mentions connection to display units and accessories, and performance studies include biocompatibility and electrical safety testing, all indicative of a hardware device.

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 (like blood, urine, or tissue) to provide information about a person's health.
  • Device Function: The Single-use Flexible Rhinolaryngoscope is a device used for direct visual examination and potentially treatment of the nasal cavity and upper respiratory tract. It is an endoscopic device used in vivo (within the body), not in vitro (in a lab setting).
  • Intended Use: The intended use clearly states "examination of nasal cavity and upper respiratory tract" and "treatment is also possible." This aligns with the function of an endoscope used for direct visualization and intervention.
  • Device Description: The description focuses on the physical characteristics and connection to display units for visualization, not on analyzing biological samples.
  • Performance Studies: The performance studies mentioned are related to biocompatibility, electrical safety, EMC, and general performance testing of the device itself, not on the accuracy of diagnostic tests performed on samples.

Therefore, this device falls under the category of a medical device used for examination and treatment, not an In Vitro Diagnostic.

§ 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)
Classification. Class II.
