The INOmax DSIR® Plus MRI delivery system is indicated for delivery of 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. The INOmax DSIR® Plus MRI is indicated for use only with MR Conditional ventilators validated to be compatible, as identified in the device labeling. The INOmax DSIR® Plus MRI is indicated for continuous integrated monitoring of inspired O2, NO2, and NO. The INOmax DSIR® Plus MRI is considered MR Conditional with the use of 1.5 Tesla and 3.0 Tesla static magnetic field scanners ONLY in areas where the field strength is less than 100 gauss. The target patient population is controlled by the drug labeling for INOMAX® and is currently neonates. The primary targeted clinical setting is a clinical 1.5 Tesla and 3.0 Tesla diagnostic imaging environment.
Device Story
Device delivers nitric oxide (NO) gas to neonates in MRI environments; utilizes dual-channel architecture. Channel 1: delivery CPU, flow controller, injector module; tracks ventilator waveforms for synchronized, proportional NO delivery. Channel 2: monitoring system with separate CPU, gas cells (NO, NO2, O2), and user interface. System includes battery for 6-hour operation and backup delivery mode (fixed 250 mL/min NO flow). Used in 1.5T/3.0T diagnostic imaging suites; operated by clinicians. Monitoring system triggers automatic NO delivery shutdown if NO concentration exceeds 100 ppm for 12 seconds. Device features GaussAlert sensors for MRI safety. Output allows clinicians to maintain therapeutic NO levels during imaging; benefits patient by enabling continuous therapy during diagnostic procedures.
Clinical Evidence
No clinical data. Substantial equivalence supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), alarm system testing (IEC 60601-1-8), and MRI-specific testing (ASTM F2052, F2119, F2503). Compatibility with respiratory devices verified via bench testing of O2 dilution, delivered pressures, delivery accuracy, and NO2 generation across multiple NO concentrations (0-80 ppm). Formative usability study conducted per ANSI/AAMI HE75.

# Description of Device
The INOmax DSIR® uses a "dual-channel" design to provide delivery of INOMAX®. The first channel has the delivery CPU, the flow controller and the injector module to ensure the accurate delivery of NO. The specially designed injector module enables tracking of the ventilator waveforms and the delivery of a synchronized and proportional dose of NO. The second channel is the monitoring system, which includes a separate monitor CPU, the gas cells (NO, NO2, and O2 cells) and the user interface including the display and a comprehensive alarm system. The dual-channel approach to delivery and monitoring permits INOMAX® delivery independent of monitoring but also allows the monitoring system to shut down INOMAX® delivery if the monitored NO concentration exceeds 100 ppm for 12 consecutive seconds. The delivery system can also shut down delivery if it detects certain serious problems with the monitoring system.
The INOmax DSIR Plus MRI incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source.
The INOmax DSIR Plus MRI 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 of NO to a patient breathing circuit. The INOblender® can also be used for backup.
# Intended Use
The INOmax DSIR® Plus MRI delivery system is indicated for delivery of 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. The INOmax DSIR® Plus MRI is indicated for use only with MR Conditional ventilators validated to be compatible, as identified in the device labeling.
The INOmax DSIR® Plus MRI is indicated for continuous integrated monitoring of inspired O2, NO2, and NO.
The INOmax DSIR® Plus MRI is considered MR Conditional with the use of 1.5 Tesla and 3.0 Tesla static magnetic field scanners ONLY in areas where the field strength is less than 100 gauss.
The target patient population is controlled by the drug labeling for INOMAX® and is currently neonates. The primary targeted clinical setting is a clinical 1.5 Tesla and 3.0 Tesla diagnostic imaging environment.
# Technological Characteristics
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 INOblender®, a stand/cart and the NO gas tanks. In this revision of the INOmax DSIR®, the cart hardware, the NO delivery cable and tubing, the gas sampling tubing, the software and the labeling have been updated.

# Summary of Nonclinical Tests
The following quality assurance measures were applied to the modification of the system:
- . Risk analysis
- Formative usability study ●
- Requirements reviews
- . Design reviews
- Testing on unit level (module verification)
- Integration testing (system verification) ●
- . Performance testing (verification)
Support for the substantial equivalence of the INOmax DSIR® Plus MRI was provided as a result of risk management and testing which included electrical safety, performance and software tests. This testing includes conformity to the FDA recognized consensus standards and voluntary standards as follows:
- . IEC 60601-1:2005 - Medical electrical equipment - Part 1: General requirements for basic safety and essential performance
- . IEC 60601-1-2:2007 - General requirements for basic safety and essential performance -Collateral standard: Electromagnetic compatibility - Requirements and tests
- . IEC 60601-1-8:2006 - General requirements for basic safety and essential performance -Collateral Standard: General requirements, tests and guidance for alarm systems in medical electrical equipment and medical electrical systems
- . ASTM F2052-06 - Standard Test Method for Measurement of Magnetically Induced Displacement Force on Medical Devices in the Magnetic Resonance Environment
- . ASTM F2119-07 – Standard Test Method for Evaluation of MR Image Artifacts from Passive Implants
- . ASTM F2503-13 - Standard Practice for Marking Medical Devices and Other Items for Safety in the Magnetic Resonance Environment
A formative usability study was conducted per ANSI/AAMI HE75 Human Factors Engineering, Design of Medical Devices, to aid in the development of hardware and software requirements and verification confirmed the INOmax DSIR® Plus MRI meets its system level requirements and that the new/modified features function as specified.
To confirm compatibility with the new respiratory care devices were set up and calibrated according to the manufacturer's recommendations and tested using the settings established for each respiratory care device test. The INOmax DSIR® was set up and calibrated according to the manufacturer's recommendations.
Five INOmax DSIR® settings were used [0 (baseline), 5. 10. 20. 40. and 80 ppm] for each mode of ventilation, as well as the Backup mode.
The measured values on the INOmax DSIR® were also recorded along with any anomalies found.
{7}------------------------------------------------
The testing concluded four requirements necessary for the INOmax DSIR® and the four respiratory care devices to be compatible:
- O2 dilution ●
- . Effect on delivered pressures
- INOmax DSIR® delivery accuracy .
- . NO2 generation
# Testing Conclusion:
The INOmax DSIR® performed within published specifications when used with each of the ventilators in both primary and backup delivery.
# Summary of Clinical Tests
The subject of this premarket submission, INOmax DSIR® Plus MRI, did not require clinical studies to support substantial equivalence.
# Conclusion
INO Therapeutics/Ikaria considers the INOmax DSIR® Plus MRI to be as safe and as effective as the predicate device, with performance substantially equivalent to the predicate device.
