2. Sample Size Used for the Test Set and Data Provenance

The provided document does not specify the sample size used for the test set or the data provenance (e.g., country of origin, retrospective/prospective). The tests performed are described as "Design verification and effectiveness test," "Safety and electromagnetic tests," and "Design verification." These descriptions typically refer to internal engineering and functional testing rather than clinical studies with human subjects.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document does not mention using experts to establish ground truth for a test set. The tests appear to be related to the device's physical and functional properties, as opposed to diagnostic performance requiring expert interpretation.

4. Adjudication Method for the Test Set

The document does not describe any adjudication method. This type of method is typically used in clinical trials where multiple readers interpret results to establish a consensus ground truth.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A multi-reader multi-case (MRMC) comparative effectiveness study was not performed or mentioned in the provided text. The submission is for device modifications to an already cleared predicate device, focusing on functional and safety aspects of the changes rather than clinical effectiveness comparisons.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

This is a medical device (anescope, proctoscope, rectoscope) for direct observation and intervention, not an imaging or algorithmic diagnostic device. Therefore, a standalone (algorithm only) study is not applicable and was not performed.

7. Type of Ground Truth Used

The ground truth for the "tests performed" appears to be based on engineering specifications, safety standards, and functional requirements to ensure the device's "safety and effectiveness." It is not based on expert consensus, pathology, or outcomes data in the clinical sense for these verification tests.

8. Sample Size for the Training Set

The concept of a "training set" is not applicable to this device's verification and validation process described. Training sets are typically used for machine learning algorithms, which are not involved here.

9. How the Ground Truth for the Training Set Was Established

Since there is no training set in the context of this device and its studies, the method for establishing its ground truth is not applicable.

The Family of THD disposable Anoscope, Proctoscope, Rectoscope and Light-scope and its predicate device are indicated for the same intended use and have the same teoops and characteristics. Both families include the anoscopes, proctoscope and the rectoscopes manufactured with the same materials and with the same dimensions.

The only difference is that the Family of THD disposable Anoscope, Proctoscope, Rectoscope and Light-scope includes also a group of different models with a different, handle:

· A type of handle for the use of the devices with an external light source
· A type of handle with a LED integrated light source

Moreover the new group of devices have the following modification

The THD Light-scope models have a white tip .
The THD Light-scope rectoscopes have the lens without hole .
Some rectoscope models are packaged with a class I device: the inflation bulb .

The modification of the handle consents to manufacture the devices with or without integrated light source. The model without light source are intended to be used with an external light source, which must be fitted on the devices as the previous cleared devices. The models with light source have the same functioning method of the previous cleared device, but they are ready to use for the physician.

The THD Light-scope models are designed with the white tip as the previous cleared rectoscope (K091490). This characteristic improves the light focus to the end of the device with a better visibility of the treated area.

The THD Light-scope rectoscope models with lens without hole are the same of the previous approved rectoscope (K091490), the only difference is that the stopper with lens at the initial part of the rectoscope is manufactured without hole.

2.4. Device Description

The devices consist of transparent plastic anoscope, proctoscope or rectoscope for diagnostic or therapeutic use.

· The Family of THD disposable Anoscope, Proctoscope, Rectoscope and Light-scope is made by two categories of devices:
