Device Description

The Aerogen® Solo Nebulizer System consists of the Aerogen® Solo Nebulizer, which has the proposed modification outlined in these 510(k) applications, and the Aerogen® Pro-X Controller (K133360 for both components and system) or the Aerogen Solo Nebulizer can also be used alternatively with the reference device - Aerogen® USB Controller (K143719).

The Aerogen® Solo Nebulizer is intended to aerosolize physician-prescribed medications for inhalation which are approved for use with a general-purpose nebulizer. It is intended for use on and off mechanical ventilation or other positive pressure breathing assistance and is intended for both intermittent and continuous nebulization.

The Aerogen® Solo Nebulizer is designed to operate in-line with standard ventilator circuits and mechanical ventilators. It operates without changing patient ventilator parameters and can be refilled without interrupting ventilation.

This submission is for a modification of the attachment process of the Aperture Plate (AP) to the Oscillator washer, both are components of the core for the Aerogen® Solo Nebulizer. The current method of attachment of the Aperture Plate to the Oscillator washer is by means of Brazing, a metal fusion process, where a copper/gold filler washer is melted in the brazing process to form the bond. The piezo is then attached using a heat cured epoxy adhesive.

AI/ML Overview

The provided documentation is a 510(k) premarket notification for a medical device, specifically the Aerogen® Solo Nebulizer System. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving efficacy or performance against a set of predefined acceptance criteria for a novel device. As such, the document does not contain information on rigorous acceptance criteria and the detailed study design typically seen for a new device's proven performance.

However, it does present "Comparative Particle Characterization Performance" data (Table 2) which can be interpreted as the performance data for the modified device in comparison to its predicate. The "Acceptance Criteria" in this context would be the demonstration that the modified device performs similarly to the predicate device, thereby maintaining substantial equivalence.

Here's an attempt to extract the requested information based on the provided document, interpreting "acceptance criteria" as "similarity to predicate device performance" for the purpose of 510(k) clearance:

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

Since this is a 510(k) showing substantial equivalence, the "acceptance criteria" for the modified device are implicitly that its performance parameters should be within a similar range or deemed not clinically significant compared to the predicate device. The document explicitly states "Similar Cascade Impactor performance and NGI performance" in the comparison column, implying this is the "acceptance" based on the presented data.

FeaturesAcceptance Criteria (Predicate Range @ 28 lpm)Reported Device Performance (Modified @ 28 lpm)Reported Device Performance (Modified @ 15 lpm - NGI)Comparison (Achieved Acceptance)
Particle size (MMAD) (microns)Albuterol: 2.90 – 3.23 Ipratropium: 3.07 – 3.42 Budesonide: 3.45 – 3.79Albuterol: 2.80 – 3.05Albuterol: 4.39 – 4.53 Ipratropium: 3.76 – 4.02 Budesonide: 4.90 – 5.01Similar Cascade Impactor performance and NGI performance

Note: For "Total Dose (ug)", the predicate values are "N/A" and the comparison states "Additional data provided," which doesn't directly fit the "acceptance criteria" comparison. The acceptance is implied by the provision of this new data for the modified device at 15 Lpm.

2. Sample sized used for the test set and the data provenance

The document does not specify the exact sample sizes (number of nebulizers tested) used for the particle characterization testing. It refers to 95% confidence intervals, which implies statistical analysis was performed on a sample. The data provenance is not explicitly mentioned (e.g., country of origin), but it is bench testing ("Non-clinical Performance Testing") rather than patient data, and it is prospective in the sense that the tests were conducted on the modified device for the purpose of this submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This document describes a 510(k) submission for a nebulizer, a physical medical device. The "ground truth" for its performance is established through objective engineering and laboratory measurements (e.g., cascade impactor, NGI) of physical parameters like particle size and dose. This is not a study involving human experts establishing ground truth for diagnostic accuracy (e.g., radiologists for medical images). Therefore, this question is not applicable in this context.

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

Not applicable. This is not a study involving human adjudication of results; it's a bench performance study.

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. This device is a nebulizer, not an AI-powered diagnostic tool for human readers.

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

Not applicable. This is not a software algorithm; it's a physical device. The performance tests ("Aerosol Performance Inter- and Intra-sample variability") are analogous to standalone performance of the physical nebulizer.

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

The "ground truth" for this device's performance is established by physical measurements using standardized laboratory equipment (Cascade Impactor, NGI) and methods to characterize aerosol properties. This is a form of objective, empirical measurement rather than subjective expert consensus or clinical outcomes data.

8. The sample size for the training set

Not applicable. This device is a nebulizer, not an AI/machine learning model that requires a training set. The "training" for a physical device involves its design, engineering, and manufacturing processes, which are guided by established principles, standards, and previous device iterations (like the predicate).

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

Not applicable. As explained above, there is no "training set" in the context of a physical device like a nebulizer in the way it's understood for AI/ML.

Discussion of Substantial Equivalence

The proposed modification of the existing Aerogen® Solo Nebulizer System and Aerogen® USB Controller System to introduce a Fully Adhesive Bonded (F.A.B) Core to the Aerogen® Solo Nebulizer is viewed as substantially equivalent to the predicate device for the following reasons:

Indications for Use -

The Aerogen® Solo Nebulizer System includes the Aerogen® Solo Nebulizer, which is intended to aerosolize physician-prescribed medications for inhalation to patients on and off ventilation or other positive pressure breathing assistance in the hospital environment.

Aerogen® Solo Nebulizer is for single-patient use. The Aerogen® Solo nebulizer is for pediatric (29 days or older) and adult patients.

The Aerogen® USB Controller System includes the Aerogen® Solo Nebulizer, which is intended to aerosolize physician-prescribed medications for inhalation to patients on and off ventilation or other positive pressure breathing assistance in the hospital environment, and on vent only in the homecare environment.

Aerogen® Solo Nebulizer is for single patient use. The Aerogen® Solo nebulizer is for pediatric (29 days or older) and adult patients.

Discussion -

The indications for use are the same for the proposed modified device and the predicate device. We have consolidated past intended use and information in previous labeling into a more complete indications for use description.

Patient Population -

Pediatric (29 days or older) through adult patients.

Discussion -

The patient population is the same for the proposed modified device and the predicates. The pediatric population is defined as 29 days or older for both the modified device and predicates.

Environment of Use -

The Aerogen® Solo Nebulizer System is intended for use in critical, acute, and sub-acute care settings, and during patient transport [Hospital].

The Aerogen® USB Controller System incorporating the Aerogen® Solo Nebulizer is intended for use in the hospital and homecare environments (on-vent only in the homecare environment).

Discussion -

The environment of use is the same for the proposed modified device and the predicate 510 (k)'s.

Technology -

The Aerogen® Solo Nebulizer technology consists of a domed vibrating mesh aperture plate, which receives liquid medication on its top surface. The plate vibrates and extrudes the liquid through the plate. It forms a fine droplet mist to create the characteristic aerosol. The fine particle mist enables drugs to be absorbed through the lungs while maintaining their integrity, providing a unique level of efficiency for the acute respiratory care market.

{13}------------------------------------------------

Discussion -

The technology is the same for the proposed modified device and the predicate and reference.

Biocompatibility of Patient Contacting Materials -

The materials in patient / drug contact are characterized as:

  • External Communicating (Indirect gas pathway)
  • Tissue / Bone / Dentin communicating .
  • . Duration of Use - permanent (> 30 days)

Discussion -

Aerogen performed biocompatibility testing as listed in Table 1 and the results were acceptable for the intended use.

Comparative Performance and Specifications

Comparative bench testing supported that the modification to the Nebulizer is equivalent to the predicate. See Table 2 above.

Discussion of Differences and Substantial Equivalence Conclusion

The performance testing and comparison of the indications for use, performance specifications to the predicate and reference demonstrate that the proposed modification to the Aerogen® Solo Nebulizer are substantially equivalent.
