AI/ML Overview

The provided text describes a medical device submission (510(k) summary) for the Rüsch Ultra Tracheoflex® Tracheostomy Set - Cuffed. It does not contain information about acceptance criteria or a study proving that a device meets those criteria in the context of a performance study involving AI or human readers, as implied by the detailed questions.

Instead, this document focuses on demonstrating substantial equivalence to predicate devices based on technological characteristics and adherence to voluntary standards.

Therefore, I cannot provide answers to most of your questions, as the information is not present in the input text.

Here's what I can extract based on the provided document:

1. A table of acceptance criteria and the reported device performance

The document doesn't provide specific quantitative acceptance criteria or detailed performance results from a study. It states that the device meets "applicable portions of the following voluntary standards." These standards likely contain implicit acceptance criteria, but they are not explicitly presented as such in the context of a performance study within this document.
- Voluntary Standards Met:
  - ASTM F1242-89, Standard Specification for Cuffed and Uncuffed Tracheal Tubes.
  - ISO 5366-1, Tracheostomy Tubes, Part 1, Connectors for Tubes for Adults
  - ISO 5366.2, Basic requirements for Tracheostomy Tubes for Adults.
  - ISO 5356: Anesthesia and Respiration Equipment, Conical Connectors, Cones and Sockets.
  - ISO 5361, Tracheal Tubes, Part 5: Requirements and Tests for Cuffs and Tubes.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not applicable. The document explicitly states: "No clinical testing was completed."

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. No clinical testing was performed, so no ground truth establishment by experts is mentioned.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. No clinical testing was performed.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. No clinical testing was performed, and this device is not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an algorithm-based device.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Not applicable. No clinical testing was performed.

8. The sample size for the training set

Not applicable. This document is not describing an AI/machine learning model, so there is no training set mentioned.

9. How the ground truth for the training set was established

Not applicable. This document is not describing an AI/machine learning model.

Identification of Legally Marketed Device to which the Submitter Claim Equivalence:

The Ultra Tracheoflex Tracheostomy set cuffed is substantially equivalent to two products marketed by Rüsch prior to May 28, 1976: These are the Safetyflex Tracheotomy Set available since April, 1974, and the Tracheoflex Tracheotomy Set, available since April 1971. This device is also similar to the Portex Flexible D.I.C. Tracheostomy Tube found substantially equivalent under K934465.

The subject devices are similar or equivalent to the predicates in significant features, materials, dimensions, and intended use.

Description of the Subject Devices:

These devices meet applicable portions of the following voluntary standards:

ASTM F1242-89, Standard Specification for Cuffed and Uncuffed Tracheal Tubes.

ISO 5366-1, Tracheostomy Tubes, Part 1, Connectors for Tubes for Adults

ISO 5366.2, Basic requirements for Tracheostomy Tubes for Adults.

ISO 5356: Anesthesia and Respiration Equipment, Conical Connectors, Cones and Sockets.

ISO 5361, Tracheal Tubes, Part 5: Requirements and Tests for Cuffs and Tubes.

Intended Use of Subject Device

Technological Characteristics of the Subject Devices

The subject device and the predicates have the same technological characteristics as the predicate devices except for:

1. The subject device's tube cuff is filled via a pilot balloon tube that ends in a spring (Bespack) valve. The Rüsch predicate devices have a balloon that ended in a capped luer. This technological improvement was made to aid in the prevention of the loss of cuff pressure due to the improper placement of the cap after cuff inflation.
1. The Rusch predicate devices had a 15 mm airway connector permanently attached to the tube flange. The subject device has a ISO standard screw-luer fitting permanently attached. This allows a locking connections to a 15 mm airway connector, a cough cap, or other connectors as needed.

No clinical testing was completed.

Regulation Number and Section

§ 868.5800 Tracheostomy tube and tube cuff.

(a)
Identification. A tracheostomy tube and tube cuff is a device intended to be placed into a surgical opening of the trachea to facilitate ventilation to the lungs. The cuff may be a separate or integral part of the tracheostomy tube and is, when inflated, intended to establish a seal between the tracheal wall and the tracheostomy tube. The cuff is used to prevent the patient's aspiration of substances, such as blood or vomit, or to provide a means for positive-pressure ventilation of the patient. This device is made of either stainless steel or plastic.(b)
Classification. Class II.
