Intended Use

The INOmax DS delivery system delivers INOmax® (nitric oxide for inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. It uses a specially designed injector module, which enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. It may be used with most ventilators. The INOmax DS provides continuous integrated monitoring of inspired O2, NO2, and NO, and a comprehensive alarm system. The INOmax DS incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source. The INOmax DS includes a backup NO delivery capability that provides a fixed flow of 250 mL/min of NO which along with user supplied 10 L/min of oxygen provides 20 ppm in the gas flow to a patients breathing circuit. It may also use the INOblender for backup. The target patient population is controlled by the drug labeling for INOmax and is currently neonates. The primary targeted clinical setting is the Neonatal Intensive Care Unit (NICU) and secondary targeted clinical setting is the transport of neonates.

Device Story

Device delivers nitric oxide (NO) gas into patient breathing circuits; tracks ventilator waveforms via injector module to provide synchronized, proportional dosing. Dual-channel design: first channel manages delivery (CPU, flow controller, injector); second channel monitors gas concentrations (NO, NO2, O2) and manages alarms. Includes backup delivery mode (fixed 250 mL/min NO flow). Used in NICU and transport; operated by clinicians. Provides continuous monitoring of inspired gases; battery-powered for 6 hours. Output informs clinician of gas concentrations and delivery status; enables precise titration of NO therapy to benefit neonates with respiratory conditions. This submission adds compatibility with Vapotherm Precision Flow system.

Clinical Evidence

No clinical studies were required to support substantial equivalence. Evidence consists of bench testing validating compatibility with the Vapotherm Precision Flow system, confirming O2 dilution, NO delivery accuracy, and NO2 generation levels remain within specifications.

Technological Characteristics

Dual-channel architecture (delivery CPU/flow controller vs. monitoring CPU/gas cells). Components include delivery unit, blender, stand/cart, and NO gas tanks. Battery-powered (6 hours). Connectivity includes ventilator waveform tracking. Complies with FDA guidance for Nitric Oxide Delivery Apparatus (January 24, 2000).

Indications for Use

Indicated for neonates requiring nitric oxide inhalation therapy. Used in NICU and transport settings.

Regulatory Classification

Identification

The nitric oxide administration apparatus is a device used to add nitric oxide to gases that are to be breathed by a patient. The nitric oxide administration apparatus is to be used in conjunction with a ventilator or other breathing gas administration system.

Special Controls

The special control for this device is FDA's “Guidance Document for Premarket Notification Submissions for Nitric Oxide Administration Apparatus, Nitric Oxide Analyzer, and Nitrogen Dioxide Analyzer.”

Appendix A - K110344 Section 5; Summary Additional Information Response.

Intended Use: The INOmax DS delivery system delivers INOmax® (nitric oxide of inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. It uses a specially designed injector module, which enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. It may be used with most ventilators. The INOmax DS provides continuous integrated monitoring of inspired O2, NO2, and NO, and a comprehensive alarm system. The INOmax DS incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source. The INOmax DS includes a backup NO delivery capability that provides a fixed flow of 250 mL/min of NO which along with user supplied 10 L/min of oxygen provides 20 ppm in the gas flow to a patients breathing circuit. It may also use the INOblender for backup. The target patient population is controlled by the drug labeling for INOmax and is currently neonates. The primary targeted clinical setting is the Neonatal Intensive Care Unit (NICU) and secondary targeted clinical setting is the transport of neonates. Technology: All revisions of INOmax DSIR utilize component technology to deliver Nitric Oxide gas to the patient. The components consist of the Delivery System unit, the blender, a stand/cart and the NO gas tanks. Determination of Summary of Non-Clinical Tests: Substantial Equivalence: The testing concluded four requirements necessary for the operation of the INOmax DSrg and Vapotherm Precision Flow system to be compatible: O2 dilution The measured O2 was within ± 4% v/v of the expected value (see Pass/Fail Table on page 8; does not include tolerance of the Precision Flow). INOmax DSm delivery accuracy The measured values were + 15% of setting or 1.3 ppm whichever is greater which is within specification of the INOmax DSIR (see Pass/Fail Table on page 8). NO2 generation The maximum generated NO2 was at 80 ppm and 100% oxygen, as would be expected. NO2 levels did not exceed 1.3 ppm on any of the flow settings (per INOmax label < 3 ppm on 100% FiO2 and any dose setting). The maximum generated NO2 at 40 ppm

{2}------------------------------------------------

Appendix A - K110344 Section 5; Summary Additional Information Response,

and 60% oxygen was 0.4 ppm (worse case per FDA guideline of < 1 ppm on 60% FiO2 at 40 ppm dose setting).

#### Backup Delivery

The delivered NO during backup delivery was within 5% (see Pass/Fail table, NO Measured section) of the INOmax DSIR specification at flow rates above 5 L/min. Measured NO2 levels did not exceed 0.2 ppm on any settings tested and 100% oxygen (per INOmax label < 3 ppm on 100% FiO2 and any dose setting). The measured O2 was within + 3% v/v of the expected value (see Pass/Fail table 100% Oxygen section of test report).

The INOmax DS revision complies to "Guidance Document for Premarket Notification Submissions for Nitric Oxide Delivery Apparatus, Nitric Oxide Analyzer and Nitrogen Dioxide Analyzer" (January 24, 2000) FDA-1157

The results of testing validated that the additional interface to the Vapotherm Precision Flow system did not alter the safety or effectiveness of the INOmax DS operation.

### Summary of Clinical Tests:

The subject of this premarket submission, INOmax DSJR interfaced to Vapotherm Precision Flow did not require clinical studies to support substantial equivalence.

Comparison of the Similarities and Differences with the Predicate Device.

Other than the item listed below, all functional/technological characteristics remain the same between the reviewed INOmax DSIR and the predicate INOmax DSJR.

#### Similarities:

No functional or technological change was made to INOmax DSJR for this 510(k) submission. The INOmax DS18 submitted for this review retains the same as the predicate device(s).

#### Differences:

Labeling change; listing and connection criteria for Vapotherm Precision Flow as an accepted interface for INOmax DSIR to be added in the INOmax DSIR Instructions for Use (IFU).

#### Conclusion:

INO Therapeutics/Ikaria considers the INOmax DSB to be as safe, as effective, and performance is substantially equivalent to the predicate device.
