Intended Use

The Maximus™ System provides features of both the Synclara™ System and the Volara™ System.

The Maximus™ System, when used as a Synclara™ Cough System is intended for use on patients who are unable to cough or clear secretions effectively due to reduced peak cough expiratory flow or respiratory muscle weakness.

The Maximus™ System, when used as a Volara™ System is intended for the mobilization of secretions, lung expansion therapy, the treatment and prevention of pulmonary atelectasis, and has the ability to provide supplemental oxygen when used with oxygen supply.

Device Description

The Maximus™ System is a 2 in 1 device which is a combination of two (2) already cleared devices. The Maximus™ System provides the individual therapies of the predicates: Vital Cough and MetaNeb®. The Maximus™ can be programmed to allow the user to provide both therapies or one only. The 2 main types of therapies are referred to as:

  • . MIE (Mechanical Insufflation-Exsufflation)
  • OLE (Oscillation and Lung Expansion) ●
AI/ML Overview

The provided text is a 510(k) premarket notification for the Maximus™ System, a medical device for respiratory therapy. It outlines the device's indications for use and compares it to predicate devices to establish substantial equivalence with respect to safety and effectiveness.

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly present a formal "acceptance criteria" table with numerical targets, as is common for diagnostic accuracy studies. Instead, it argues for substantial equivalence to predicate devices. This means the primary acceptance criterion is that the Maximus™ System performs functionally and safely similar to its predicates (MetaNeb® and Vital Cough) and does not raise new or different questions of safety or effectiveness.

The comparison tables (Table 1, Table 2, Table 3 – although some are presented partially) serve as the 'reported device performance' against the implicit acceptance criterion of equivalence to the predicates.

Feature / Performance MetricAcceptance Criteria (Implicit - Equivalence to Predicates)Reported Maximus™ System Performance
Indications for UseIdentical to predicates (MetaNeb® K124032, K151689; Vital Cough K132988)Identical for mobilization of secretions, lung expansion therapy, treatment and prevention of pulmonary atelectasis, ability to provide supplemental oxygen. The Maximus™ System combines features of Synclara™ (MIE) and Volara™ (OLE).
Patient PopulationIdentical to predicatesVolara™ mode: Adult, Child > 2 years old (acute); >5 years old (home care). Synclara™ mode: Adult and pediatric. (Identical to respective predicates).
Environment of UseIdentical to predicatesHospital, sub-acute facilities, nursing care, homecare. (Identical to respective predicates).
OLE: Peak Positive Pressures≤ 30 cmH2O (Predicate MetaNeb®)Up to 70 cmH2O (Supported by reference device Bird IPV K895425 with 80 cmH2O)
OLE: Patient Circuit - Adjustable ResistancePresent (Predicate MetaNeb®)No resistance adjustment feature; therapy settings done at control unit.
MIE: Max Positive and Negative Pressures+50 cmH2O / -50 cmH2O (Predicate Vital Cough)+70 cmH2O / -70 cmH2O (Supported by reference device Philips Respironics Cough Assist T70 K121955 with same pressures). Max pre-set of +50 cmH2O in home setting.
Nebulizer PerformanceSubstantially equivalent to predicateComparative nebulizer performance across all therapy modes and pressure ranges demonstrated substantial equivalence with the Philips SideStream nebulizer. Mouthpiece vs. face mask performance also equivalent.
Software Control / User InterfaceManual (Predicates)Software-controlled, GUI screen. Performance and usability evaluated.
Pulse Oximeter ConnectionNot offered (Predicates)Can connect via Bluetooth to cleared Beijing Choice Electronic Technology Co., Ltd. Fingertip Pulse Oximeter (K142888). Displays heart rate and SpO2. (This is an added feature, not a comparative one, but is deemed not to raise new safety/effectiveness questions).
BiocompatibilityMeet applicable requirements (ISO 10993, ISO 18562)Materials in gas and fluid pathway tested per ISO 10993-1 and ISO 18562 and found to meet applicable requirements.
Bench Testing PerformanceSubstantially equivalent to predicatesDemonstrated equivalence through: Simulated Life Cycle, Biocompatibility, Software V&V, Electrical safety/EMC, Comparative Performance in CHFO, CPEP, Aerosol and MIE modes, Comparative Nebulizer Performance, Inter-/Intra-sample variability, pre-/post-cleaning nebulizer performance, Usability.

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

The document primarily describes bench testing and comparative performance testing against predicate devices and reference devices. It does not refer to clinical studies with patient test sets in the context of diagnostic accuracy. Therefore, details regarding "sample size for the test set" or "data provenance (country of origin, retrospective/prospective)" for patient data are not applicable to this 510(k) submission, which focuses on substantial equivalence based on performance and safety characteristics compared to existing devices.

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)

This information is not provided. As this is a medical device submitting for substantial equivalence based on engineering and performance criteria rather than diagnostic accuracy with a ground truth established by experts, this type of detail is not expected or relevant in this context. The "ground truth" here is the established safe and effective operation of the predicate devices.

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

Not applicable. There is no human adjudication of a "test set" in the context of diagnostic performance as described in the document.

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. The Maximus™ System is a therapeutic device (noncontinuous ventilator), not a diagnostic AI system that "assists human readers." Therefore, an MRMC comparative effectiveness study is not relevant to this submission.

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

Not applicable. The Maximus™ System is a physical electro-mechanical device that delivers therapy, not a standalone algorithm.

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

The "ground truth" in this 510(k) submission for substantial equivalence is the established safe and effective performance of the predicate devices (Hill-Rom MetaNeb® and Vital Cough), as well as reference devices (Bird IPV and Philips Respironics Cough Assist T70) for specific performance parameters. The device's performance is compared against these established benchmarks through various bench tests.

8. The sample size for the training set

Not applicable. The document describes a physical medical device, not a machine learning model that requires a "training set."

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

Not applicable. As there is no machine learning model or "training set," this question is not relevant.

Substantial Equivalence Discussion

The Maximus™ system is viewed as substantially equivalent to the predicate devices because:

Indications - The proposed indications for use for mobilization of secretions, lung expansion therapy, the treatment and pulmonary atelectasis, and has the ability to provide supplemental oxygen when used with compressed oxygen are identical to the predicates. Discussion: The indications for use are identical to the predicates Hill-Rom MetaNeb® system (K124032) and Vital Cough (K132988). The subject device is a new design of these technologies. We have of the patient interface to include a face mask in the home setting.

Patient Population – The patient populations are identical to the predicates. Discussion: We have not changed the patient populations vs. the predicates.

Environment of Use – The environments of use identical to the predicates. Discussion: We have not changed the use environments.

{12}------------------------------------------------

Technology - The Maximus™ is a redesign of the combination of the MetaNeb® system and the Vital Cough system into a single unit. The software-controlled Maximus™ replaces the manual control systems. Functionally the performance and therapy mode functions and performance are identical to the respective predicates.

We have added changes to some of the pressure limits based upon reference devices with similar indications for use and clinician input.

The Maximus™ can connect to a cleared pulse oximeter via BLE and can display only the heart rate and SpO2 for the convenience of the user. Connects to K142888. The predicates do not have the feature.

Discussion: The design of Maximus™ is different from the predicates in that it allows for software control of settings and the user interface is a GUI screen. We have evaluated the performance and usability with different user types.

Performance – The basic performance features and parameters are identical to the predicates. We have proposed some changes listed below with their respective rationale.

Rationale and Support of Product Differences / Modifications

OLE

Higher Peak Positive Pressures

We have found that clinicians want to provide a higher Positive Peak Pressure up to 70 cm H2O vs. the original 30 cmH2O. The reference device Bird IPV (K895485) has similar indications for use and patient population and provides peak expiratory pressures up to 80 cm H2O.

Patient Circuit - Adjustable Resistance

The predicate patient circuit has a selector ring which could be adjusted manually. The proposed change in Maximus™ with the touch screen is that controls would be performed on-screen.

MIE

Higher Maximum Positive and Negative Pressures

We have found that clinicians want to be able to provide a wider range of Maximum Positive and Negative pressures during couch assist. We are proposing to increase the range from +50 cm H2O to +70 cm H2O. The reference Philips Respironics Cough Assist T70 (K121955) has the same indications for use and population that provides pressures of +70 cm H2O.

Nebulizer Performance

The comparative nebulizer performance across all therapy modes and range of pressures demonstrated that the Maximus performance with the Philips SideStream nebulizer was substantially equivalent to the predicate. In addition, testing demonstrated that the performance with a mouthpiece vs. a face mask were equivalent. Aerosol may not be delivered when the in-line ventilator adapter is used.

Manual Mode

The Manual Mode is restricted to highly trained home users via "pass key".

The differences presented above have not raised new or different questions of safety or effectiveness from the predicates or the reference devices cited.

Non-clinical Comparative Performance

Biocompatibility of Patient Contacting Materials - The materials in the gas and fluid pathway are considered as having 2 types of patient contact:

  • External communicating, tissue contacting, permanent duration and
  • . Surface contact, mucosal contact, permanent duration for the mouthpiece
  • The materials have been tested per ISO 10993-1 and ISO 18562.

Discussion: All associated materials in the gas or fluid pathway have been tested per ISO 10993-1 and ISO 18562 and found to meet the applicable requirements.

Bench Testing - We performed a series of non-clinical bench testing to demonstrate that the Maximus™ system is equivalent to the predicates. These tests included:

  • Simulated Life Cycle testing including Cleaning ●
  • Biocompatibility Main Unit and Patient Circuit Components .
    • o ISO 10993
    • o ISO 18562
  • Software verification and validation ●
  • Electrical safety, EMC ●
  • Comparative Performance in CHFO, CPEP, Aerosol and MIE modes
  • Comparative Nebulizer Performance across all therapy modes for adult and pediatric flow ● rates
  • . Inter- and Intra-sample variability and pre- and post-cleaning nebulizer performance
  • . Usability

The comparative testing demonstrates that the proposed device is substantially equivalent to the predicate devices.

Comparative Performance

We compared the proposed Maximus across all therapy modes vs. the applicable predicate and reference devices.

These tests included:

  • Continuous High Frequency Oscillation (CHFO) ●
  • Continuous Positive Expiratory Pressure (CPEP) ●
  • Aerosol ●
  • . Comparative Bench Testing of MIE (Mechanical Insufflation-Exsufflation)
  • Comparative Nebulizer Performance across all therapy modes for adult and pediatric flow . rates

Discussion: The differences in some of the pressure limits is supported by the cleared reference devcies which have the same indications for use, patient population and environments of use. Any difference in performance or pressure limits do not raise new risk concerns and thus the Maximus™ system can be found to be substantially equivalent to the predicates.

Substantial Equivalence Conclusion

Based upon the risk analysis, comparative performance testing and the usability testing we have demonstrated that the proposed device and predicates can be found to be substantially equivalent.
