The summary describes a passive breathing circuit with heated wires and connectors, and there is no mention of AI or ML in the intended use, device description, or performance studies.
No.
The device acts as a conduit for respiratory gas and aids in maintaining temperature and minimizing condensation, but it does not directly treat a medical condition.
No
The device is described as a "conduit for respiratory gas between a patient and a ventilator or Infant Flow Generator" and includes heated wires to maintain temperature and minimize condensation. Its purpose is to facilitate gas delivery and conditioning, not to diagnose a condition or illness.
No
The device description clearly states it is made of corrugated tubing and includes heated wires, which are physical hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use clearly states the device is a "conduit for respiratory gas between a patient and a ventilator or Infant Flow Generator." It also mentions heated wires for maintaining temperature and minimizing condensation. This describes a device used in vivo (within the body or in direct contact with the body) for respiratory support, not for testing samples in vitro (outside the body).
- Device Description: The description reinforces the function as a conduit for respiratory gas and its connection to ventilators and humidifiers. It describes physical components like tubing and connectors.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment. The device's function is purely mechanical and related to delivering respiratory gas.
In summary, the Neonatal ConchaSmart Breathing Circuits are a medical device used for respiratory support, not for performing diagnostic tests on biological samples.

E. Predicate Device
The Neonatal ConchaSmart Breathing Circuits are substantially equivalent to the following devices:
- K103767 RT265 and RT266 Dual Heated Infant Breathing Circuits .
In addition, the following devices are used as reference devices as described:
K140556 has been added as a reference 510(k). The primary reason for referencing K140556 is that this is the adult version of the proposed device. The adult breathing circuits were added as a reference for the following primary reasons:
- . Different technological characteristics (single vs. dual limb) do not raise different questions of safety and effectiveness from the predicate device since the adult circuit is available in both configurations.
- . The materials used in the proposed neonatal breathing circuit and the reference are similar and well understood.
- . The useful life testing strategy of the reference device was accepted. It is an equivalent test method to the proposed device.
- . The heated wires used in the reference device are similar to the proposed device. The intent of using the adult circuits as a reference was to show that Teleflex has market knowledge of the interaction of this type of heated wire being used with similar materials with the Hudson RCI Neptune Heated Humidifier system.

K151959 has been added as a reference 510(k). The primary reason for referencing K151959 the following:
- . It is a single limb breathing circuit cleared to be used with a heated humidifier for neonatal and infant patient populations.
- . The testing related to the single limb configuration was similar (biocompatibility to ISO 10993; circuit construction and performance to ISO 5356-1, ISO 5367, and ISO 8185; and electrical testing to IEC 60601-1).

Similarities
The proposed device and predicate are similar in that they have the same intended use and same indications for use. They are used for the same patient population in the dual limb configuration and were subjected to and passed testing to the same performance (ISO 5367, ISO 8185, ISO 5356-1), biological (ISO 10993), and electrical (IEC 60601-1 and IEC 60601-1-2) standards.
Differences
The main differences are the limb configuration of single limb, the flow rates, and the use of the device with the Neptune Heated Humidifier. With respect to the limb configurations, a reference predicate was introduced that is a single limb configuration cleared for the neonatal / infant population for use with a heated humidifier. The physical and electrical characteristics of the proposed device were testing according to IEC 60601-1 and IEC 60601-1-2 and were appropriate for the indicated Heated Humidifier (Hudson RCI Neptune). For the tubing dimensions, testing to ISO 5367 showed that the proposed device and the predicate were substantially equivalent.

K. Conclusion
As with the predicate, all of the acceptance criteria required through the use of the harmonized standards (including performance, biocompatibility, and electrical as discussed above) were met for the proposed device. In addition, the circuit was found to function as intended when used with the Neptune Heated Humidifier, for which it is intended to use. The device data and test results demonstrate that the devices meet the applicable standards for breathing circuits and are substantially equivalent to the predicate device.
