You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

Common/Usual Name: Noncontinuous ventilator (IPPB) Classification: NHJ, 868.5905 Predicate Device: BiWaze Clear System, ABMRC LLC, K231728 Common/Usual Name: Noncontinuous ventilator (IPPB) Classification: NHJ, 868.5905 # Device Description: The proposed device is similar to the predicate cleared under K231728 except for the addition of Bluetooth connectivity and the addition of an FDA-cleared filter (K192713). The BiWaze Clear System assists patients in loosening and mobilizing secretions as well as treating and preventing atelectasis by providing lung expansion and high frequency oscillation therapies. The oscillating lung expansion therapy of the BiWaze Clear System is intended to reduce airway obstructions caused by secretions occupying the lower airways, prevent respiratory tract infections, re-expand the collapsed areas of the lung, thereby enhancing gas exchanges and reducing inflammatory response. BiWaze Clear delivers three therapies: Positive Expiratory Pressure (PEP), Oscillation (OSC), and nebulizer (NEB). - Positive Expiratory Pressure (PEP): During PEP, the system delivers a programmed positive pressure which the patient exhales against to open and expand the patient's airways. The nebulizer can be configured to run during PEP therapy to help move saline throughout the airways. - Oscillation (OSC): During OSC, the system oscillates the airways with pulses of positive pressure to thin secretions and mobilizes them from the lower airways to the upper airways so they can be coughed or suctioned out. The nebulizer can be configured to run during OSC therapy to help move saline throughout the airways. - Nebulize (NEB): During NEB, the system powers only the Aerogen Solo vibrating mesh nebulizer. This therapy gives the patient a break from PEP or OSC while the patient receives their nebulized saline. The BiWaze Clear System can be used in conjunction with the various patient interfaces such as facemask, mouthpiece or a trach adapter which connects to a patient's endotracheal or tracheostomy tube, or in-line with a ventilator. It is intended to deliver therapy to pediatric and adult patients in acute, post-acute and home care {5} 510(k) Summary Page 2 of 6 K260604 settings. The BiWaze Clear System provides a closed-circuit therapy with the Dual Lumen Breathing Circuit that prevents aerosolized exhalation of air from escaping the handset or breathing tube before being filtered by a coaxial bacterial/viral filter. The BiWaze Clear System consists of a main controller and single patient, multi-use breathing circuit which includes various patient interface options. - Mouthpiece - Face Mask - Trach Adapter - Two Step Adaptor ### Principle of Operation The BiWaze Clear System delivers positive expiratory pressure for lung expansion therapy and produces high-frequency oscillations up to 300 beats per minute (5 Hz) and peak positive pressures ≤ 70 cmH₂O to break up mucus and move it up the mucociliary escalator. The device can deliver nebulized saline during oscillation and positive expiratory pressure phases. The nebulizer can also be used independently to deliver aerosol saline. ### Indications for Use: The BiWaze Clear System is indicated for the loosening and mobilization of secretions, lung expansion therapy, the treatment and prevention of pulmonary atelectasis, and can provide supplemental oxygen when used with an oxygen supply. The system provides three therapies: Positive Expiratory Pressure (PEP), Oscillation (OSC), and delivery of saline via integrated nebulizer (NEB). The BiWaze Clear System is for use on adult or pediatric patients in acute care (aged 2 years and older) and home care environments (aged 5 years and older). The BiWaze Clear System is compatible with various patient interfaces including face mask, mouthpiece, a trach adapter for connection to an endotracheal or tracheostomy tube in acute and home care settings. The BiWaze Clear System may be used in-line with a ventilator in acute care environments only. ### Patient Population: The BiWaze Clear System is for use on adult or pediatric patients in acute care (aged 2 years and older) and home care environments (aged 5 years and older). ### Environments of use: The BiWaze Clear System is used in acute care (aged 2 years and older) and home care environments (aged 5 years and older). ### Substantial Equivalence Discussion The BiWaze Clear System is viewed as substantially equivalent to the predicate devices because: {6} K260604 510(k) Summary Page 3 of 6 Indications – The proposed indications for use for mobilization of secretions, lung expansion therapy, treatment and prevention of pulmonary atelectasis, and ability to provide supplemental oxygen when used with compressed oxygen are identical to the predicate. Patient Population – The patient population is identical to the predicate. Environment of Use – The environment of use is identical to the predicate. However, BiWaze Clear use in-line with ventilator is intended only in the acute care environment. Technology – Functionally, the performance and therapy mode functions are similar to the predicate device. Performance Data: Performance bench testing was conducted related to the addition of a filter to the breathing circuit. The comparative testing to the predicate was found to be substantially equivalent. Biocompatibility: The design and materials in the gas and fluid pathways are identical to the predicate, BiWaze Clear System (K231728). ### Discussion of Differences The difference between the proposed device and the predicate are: - Enabling Bluetooth connectivity - Addition of an FDA-cleared filter to the breathing circuit These changes do not raise different questions of safety and effectiveness compared to the predicate and can be considered substantially equivalent. ### Nonclinical Testing Summary Based upon the modification the following nonclinical testing performed as part of demonstrating substantial equivalence to the predicate. - Software verification and validation was performed - Cybersecurity - Wireless co-existence testing - IEC 60601-1 - IEC 60601-1-2 - Testing was conducted to assess device performance with the addition of a filter to the breathing circuit. The comparative testing was performed with and without the filter. Testing with the filter was found to be substantially equivalent to the predicate. Testing was performed with PAP and OSC therapies and included various, clinically relevant, pressures and frequencies (low, medium, and high) with a range of resistance and compliance settings to simulate patient condition and age (adult vs. pediatric). In all cases the modified device met it performance specifications and can be considered substantially equivalent to the predicate. {7} K260604 510(k) Summary Page 4 of 6 Table - Comparison of Subject vs. Predicate | | Subject Device BiWaze Clear | Predicate BiWaze Clear – K231728 | Comparison | | --- | --- | --- | --- | | Product Code | NJH - Noncontinuous ventilator (IPPB) | NJH - Noncontinuous ventilator (IPPB) | Identical | | CFR | 868.5905 | 868.5905 | Identical | | Indications for Use | The BiWaze® Clear System is indicated for the loosening and mobilization of secretions, lung expansion therapy, the treatment and prevention of pulmonary atelectasis, and can provide supplemental oxygen when used with an oxygen supply.
