No
The description focuses on the mechanical and electronic components for extracorporeal circulation and gas exchange, with no mention of AI or ML for data analysis, decision support, or control.
Yes
This device is identified as a therapeutic device because it provides "extracorporeal circulation and physiologic gas exchange (oxygenation and CO2 removal) of the patient's blood" for individuals experiencing acute respiratory or cardiopulmonary failure. These actions directly treat a medical condition.
No
The Novalung System is described as a blood oxygenation and carbon dioxide removal system designed to provide extracorporeal cardiac and/or pulmonary support. Its purpose is to provide long-term respiratory/cardiopulmonary support and physiological gas exchange, which are therapeutic and life-sustaining functions, not diagnostic ones. While it monitors parameters, this is for controlling the support, not for diagnosing a condition.
No
The device description clearly outlines multiple hardware components including a console, power supply, sensor box, pump drive, and the XLung kit with tubing, oxygenator, and blood pump head. While it has a control panel with a touchscreen display, it is part of a larger hardware system for extracorporeal circulation and gas exchange.
Based on the provided information, the Novalung System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Novalung System Function: The Novalung System is an extracorporeal system that directly interacts with the patient's blood outside the body to perform gas exchange (oxygenation and CO2 removal). It is a life support system, not a diagnostic tool that analyzes samples.
- Intended Use: The intended use clearly states it provides "assisted extracorporeal circulation and physiologic gas exchange" for respiratory/cardiopulmonary support. This is a therapeutic intervention, not a diagnostic one.
- Device Description: The description details components for blood circulation, oxygenation, and monitoring of physiological parameters within the extracorporeal circuit. It does not mention any components or processes for analyzing patient samples.
Therefore, the Novalung System falls under the category of a therapeutic medical device, specifically an extracorporeal life support system, rather than an In Vitro Diagnostic device.

The system performed well in providing both yeno-venous and yeno-arterial support. Outcome and rate of technical complications is comparable to ELSO registry data. No treatment was discontinued due to device malfunction. The clinical data justify the long-term use of the Novalung System for respiratory and/or cardiopulmonary support.
ર.જ. Conclusion
The Novalung System meets the special controls in FDA's final order (81 FR 7451, February 12, 2016) and is substantially equivalent to the reference predicate devices. The information and data in this Traditional 510(k) demonstrate that the Novalung system is substantially equivalent to the predicate and reference predicate devices for long-term (> 6 hours) respiratory/cardiopulmonary support that provides assisted extracorporeal circulation and physiologic gas exchange (oxygenation and CO2 removal) of the patient's blood in patients with acute respiratory failure or acute cardiopulmonary failure, where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent.
