The FinESS Endoscope is intended to provide a means to visualize the maxillary sinus cavity and deliver the FinESS balloon dilation catheter to treat the maxillary sinus ostium and the ethmoid infundibulum in adults with a trans-antral approach. The endoscope is part of the FinESS Sinus Treatment and is inserted via a sterile access sheath through the canine fossa.
The FinESS Endoscope is a fiber optic based, manually operated, reusable rigid antroscope designed for performing the FinESS Sinus Treatment procedure. It is short, all metal and fully immersible. It is labeled non-sterile and must be cleaned and disinfected or sterilized prior to use. The endoscope is compatible with standard "B" mount camera couplers, and comes with two light post adapters, which allows the endoscope to be compatible with most commonly used light guides. The endoscope also has a working channel that allows for delivery of the FinESS balloon dilation catheter to treat the maxillary ostium and ethmoid infundibulum. The FinESS Endoscope is part of and used with the FinESS Sinus Treatment [K081542] and insertion of the endoscope is performed using a sterile access sheath [K091681].
Based on the provided text, the FinESS Endoscope is a medical device that received 510(k) clearance. This means it demonstrated substantial equivalence to a legally marketed predicate device, rather than undergoing a de novo approval process that would typically involve establishing novel acceptance criteria and extensive standalone performance studies for an entirely new device.
Therefore, the structure of the provided content focuses on showing equivalence rather than proving a device meets predefined acceptance criteria for novel performance claims.
Here's an analysis of the provided information, noting what is present and what is absent regarding acceptance criteria and study details for AI/ML devices:
1. Table of Acceptance Criteria and Reported Device Performance
The submission does not define specific acceptance criteria in terms of numerical performance metrics (e.g., sensitivity, specificity, accuracy) that an AI/ML device would typically be evaluated against. Since this is a traditional medical device (an endoscope) and not an AI/ML device, its performance is assessed against design specifications and intended function rather than diagnostic or analytical performance metrics.
The "Performance Data" section states: "The testing showed that the device meets design specifications and performs as intended." This is the highest level of detail provided regarding performance.
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: Not applicable in the context of an AI/ML diagnostic or predictive model. The performance tests mentioned are related to engineering and usability aspects of the endoscope itself.
- Data Provenance: Not applicable. The "cadaver studies" mentioned are for testing physical performance and usability, not for training or testing an AI model on patient data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Not applicable. "Ground truth" in the AI/ML sense (e.g., expert consensus on image labels) is not relevant for this type of traditional device submission. The verification of design specifications would involve engineers and quality assurance personnel.
4. Adjudication Method for the Test Set
Not applicable. There is no concept of adjudication (e.g., 2+1, 3+1) as there are no diagnostic or interpretive outputs being evaluated from the device that would require human expert consensus.
5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study
No. This type of study is not mentioned because it is designed to evaluate human reader performance with and without AI assistance, which is irrelevant for a rigid endoscope.
6. Standalone Performance Study
Yes, in a sense, a "standalone" assessment of the device's physical and functional performance was conducted. The "Performance Data" section details various tests that were performed on the device itself to ensure it functions as designed and intended. These include:
- Biocompatibility testing
- Dimensional verification
- Cadaver studies (for physical use and visualization)
- Manual cleaning validation (utilizing total organic carbon as study endpoint)
- Manual high level disinfection validation
- Sterilization validation of STERRAD NX system (per ISO 14937)
- Compatibility testing
- Storage and transportation testing
7. Type of Ground Truth Used
The ground truth for this device's performance is its adherence to design specifications, industry standards, and regulatory requirements for medical devices (e.g., biocompatibility standards, sterilization efficacy, dimensional accuracy).
8. Sample Size for the Training Set
Not applicable. As a traditional medical device, there is no "training set" in the context of machine learning. The device's design is based on engineering principles and predicate device experience, not iterative learning from data.
9. How the Ground Truth for the Training Set Was Established
Not applicable.
Summary of Device Performance Study as Described:
The study conducted for the FinESS Endoscope was a series of engineering and validation tests demonstrating that the device meets its design specifications and performs its mechanical and functional tasks as intended, particularly in terms of visualization, accessory delivery, and reprocessing. It showed substantial equivalence to its predicate device based on these performance characteristics, ensuring it maintains the same safety and effectiveness profile. No AI/ML components are involved, and thus, typical AI/ML evaluation metrics, studies, and data provenance requirements are not relevant.
§ 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)
