The device description and performance studies focus on mechanical and physical properties of the oxygenator, filter, and reservoir. There is no mention of AI, ML, or any software-driven analytical or predictive functions.
Yes
The device is intended to exchange gases in blood, filter non-biologic particles, warm or cool blood, and store blood during cardiopulmonary bypass surgery for adult and small adult patients, all of which are therapeutic interventions.
No
Explanation: The device is an oxygenator used for gas exchange and blood filtration during cardiopulmonary bypass surgery. Its intended use is to exchange gases, filter particles, and manage blood temperature, which are therapeutic and supportive functions, not diagnostic.
No
The device description clearly outlines multiple hardware components including porous fibers, a heat exchanger made of Polyethylene Terephthalate tubes, an integrated arterial filter, and a hardshell reservoir. The performance studies also focus on the physical characteristics and performance of these hardware components.
Based on the provided text, the Capiox® NX19 Oxygenator with Integrated Arterial Filter and UltraPrime™ Technology is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is used to "exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of adult and small adult patients during cardiopulmonary bypass surgery." This describes a device that interacts directly with the patient's blood within the body's circulatory system during a surgical procedure.
- Device Description: The description details how the device functions to facilitate gas exchange, filter blood, and control blood temperature during extracorporeal circulation. This is a life-support function performed outside the body but directly connected to the patient's blood flow.
- IVD Definition: An In Vitro Diagnostic (IVD) device is defined as a medical device intended for use in vitro for the examination of specimens, including blood, tissues, and body excretions, derived from the human body, solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.
The Capiox® NX19 Oxygenator does not examine specimens in vitro to provide diagnostic information. It is a therapeutic device used to support physiological function during surgery.

Device Description
The Capiox® NX19 Oxygenator utilizes porous fiber technology to facilitate the transfer of gases between a blood-phase environment and a gas-phase environment for the intent of satisfying the gas exchange needs of a patient during cardiopulmonary bypass surgery. A fiber bundle offers the porous membrane surface to sufficiently permit the movement of gases through the walls of the hollow fibers via diffusion.
The Capiox® NX19 Oxygenator device has an integrated heat exchanger that is comprised of Polyethylene Terephthalate tubes arranged in a cylindrical shape. The circulating blood contacts the exterior surface of these tubes. Temperature-controlled water distributed from an external water bath fills the interior of the tubes. The heat exchanger material permits heat transfer to occur across the walls of the heat exchanger tubes to achieve the necessary temperature of the circulating blood.
The Capiox® NX19 Oxygenator device can be operated at flow rates up to 8 liters per minute (1/min) and at a minimum flow rate of 2.0 liters per minute (1/min) or 0.5 liters per minute (1/min) for up to 2 hours.
The integrated arterial filter of the Capiox® NX19 Oxygenator device relies upon mechanical entrapment of particulates and emboli within the filter mesh as a means to remove those particulates from the blood.
The hardshell reservoir is used to store blood during extra-corporeal circulation from the venous line and the cardiotomy line. The reservoir contains a venous section that is comprised of a filter and defoamer to facilitate air bubble removal. The cardiotomy section of the reservoir contains a filter to remove particulate matter and a defoamer to facilitate air bubble removal. The 4-liter reservoir may be used for Vacuum Assisted Drainage procedures and Post-Operative Chest Drainage Procedures.

Principles of Operation and Technology
The Capiox® NX19 Oxygenator utilizes porous fiber technology to facilitate the transfer of gases between a blood-phase environment and a gas-phase environment for the intent of satisfying the gas exchange needs of a patient during cardiopulmonary bypass surgery. A fiber bundle offers the porous membrane surface to sufficiently permit the movement of gases through the walls of the hollow fibers via diffusion.

The operation and technology employed by the new NX19 Oxygenator device are consistent with the operation and technology of the predicate FX25 Advance Oxygenator device.
Design and Materials
The primary differences in the design and materials between the Capiox® NX19 Oxygenator and the predicate device are:
- · Reduction in the diameter of the polypropylene oxygenator fibers vs. the predicate;
- · Higher Molecular weight of Polymethoxyethyl acrylate (PMEA) solution vs. the predicate;
- · Difference in the materials of construct of the heat exchanger plastic vs stainless steel;
- · The NX19 has a lower priming volume vs. the predicate device.
- · The NX19 utilizes pre-heat exchanger vent fiber to facilitate air removal during priming
Reduction in diameter of the oxygenator fibers:
The Capiox® NX19 Oxygenator utilizes an oxygenator fiber that has a diameter approximately 40% smaller than that of the predicate device. This smaller diameter allows for a larger percentage of the blood in the oxygenator to be in contact with the surface area of the fibers. By increasing this contact, similar gas exchange performance can be achieved with a lower blood volume. The smaller fiber diameter allows the NX19 oxygenator to have a surface of approximately 1.9m² compared to the approximately 2.5m² surface area of the predicate device while still achieving equivalent gas exchange performance.
Higher Molecular weight of Polymethoxyethyl acrylate (PMEA) solution:
The X-Coating™ solution utilized to coat the NX19 Oxygenator varies from the solution that is used to coat the predicate device. The NX19 X-Coating™ solution is Polymethoxyethyl acrylate (PMEA). This solution has a molecular weight of 400kDa. The solution for the predicate device is also PMEA solution, but has a lower molecular weight. The predicate X-Coating™ has a molecular weight of 85kDa. This increased molecular weight with the NX19 device allows for increased stability of the coating when applied to the polypropylene fibers of the oxygenator bundle.
Difference in the materials of construct of the heat exchanger – plastic vs stainless steel:
The material and the surface area of the heat exchanger in the Capiox® NX19 Oxygenator varies from the predicate device. The heat exchanger tubes in the NX19 Oxygenator are made of Polyethylene Terephthalate (PET) plastic material differs from the stainless steel bellows in the heat exchanger of the predicate device. The surface area of the PET heat exchanger tubes is 0.43m² in the NX19, which is a larger surface area than the 0.2m² in the predicate FX25. This increased surface area ensures that adequate (equivalent) heat exchange is achieved.
The NX19 has a lower priming volume vs. the predicate device:
The prime volume of the Capiox® NX19 Oxygenator is 185mL, which is lower than the 260mL priming volume of the predicate FX25 device. The reduced prime volume helps reduce the amount of blood that needs to be removed from a patient which, in turn, reduces the need for hemo-dilution.

Image /page/6/Picture/0 description: The image shows the logo for Terumo. The logo consists of a red swoosh above the word "TERUMO" in green, block letters. The swoosh is angled upwards from left to right.
Both the new NX19 Oxygenator and the predicate FX25 Oxygenator are comprised of the same generic materials, and they both feature common design characteristics. The notable differences in materials and design (as identified above) do not raise any issues of safety or effectiveness. Both devices are deemed to be clinically acceptable.
The NX19 utilizes pre-heat exchanger vent fiber to facilitate air removal during priming To facilitate air removal during priming, the NX19 utilizes pre-HE microporous fiber, oxygenator microporous fiber and a purge port. The FX25 predicate device relies on oxygenator microporous fiber and a purge port for facilitation of air removal during priming (without the presence of pre-HE microporous fiber).
Performance:
Terumo Cardiovascular Systems has conducted in-vitro performance evaluations for the purpose of demonstrating that the Capiox® NX19 Oxygenator is substantially equivalent to the predicate the Capiox® FX25 Advance Oxygenator. Clinical studies involving patients are not necessary to demonstrate substantial equivalence of the subject device to the predicate device. Substantial equivalence is demonstrated with the following in-vitro performance evaluations:
- Gas Transfer and Pressure Drop Performance ●
- Heat Exchanger Performance o
- Hemolysis Performance •
- . Air Removal Performance
- . Capnography Assessment
- Connection Strength of Ports .
- Filtration Efficiency .
- Mechanical Integrity .
- Luer Port Assessment .
- NX Blood Compatibility .
In addition to the verification testing listed above conducted on the oxygenator, the reservoir testing included in K151791 supports the increased maximum flow rate of the reservoir. The reservoir to be offered with the NX19 oxygenator is the EXACT SAME RESERVOIR that is offered with the FX25 and was cleared in K151791. The verification testing listed below was conducted on the reservoir and presented in K151791. This testing is also presented in Appendix D of this submission:
- . Testing of Air Handling
- Testing of Hemolysis .
- Testing of Venous Defoaming .
- Testing of Pressure Drop .
- Testing of Clotting .
