Intended Use

The Affinity NT Oxygenator with Cortiva™ BioActive Surface is intended to be used in an extracorporeal perfusion circuit to oxygenate and remove carbon dioxide from the blood and to cool or warm the blood during routine cardiopulmonary bypass procedures up to 6 hours in duration.

Device Story

Single-use hollow fiber oxygenator; integral component of cardiopulmonary bypass circuit. Receives blood from patient via blood pump; oxygenates blood; removes carbon dioxide; cools or warms blood via integrated heat exchanger. Used in cardiac surgery; operated by perfusionists/clinicians. Output is processed blood returned to patient. Device modification involves updated labeling regarding disinfectant use in water path. Benefits include maintenance of gas exchange and temperature control during bypass.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing, including pressure integrity, burst testing, and port break force analysis, alongside material characterization of the heat exchanger water path.

Technological Characteristics

Hollow fiber oxygenator with integrated heat exchanger and arterial filter. Features Cortiva™ BioActive Surface. Single-use, sterile, non-toxic, non-pyrogenic. Mechanical operation for gas exchange and thermal regulation.

Indications for Use

Indicated for patients undergoing routine cardiopulmonary bypass procedures requiring extracorporeal blood oxygenation, carbon dioxide removal, and temperature regulation for up to 6 hours.

Regulatory Classification

Identification

# Predicate Device:

Medtronic Affinity NT Oxygenators (K143073)

# Device Description

The device listed in this 510(k) Notification is a single use, non-toxic, non-pyrogenic, and is supplied sterile in packaging.

The Medtronic Affinity NT Oxygenator is a single use device designed to oxygenate and remove carbon dioxide from the blood and with the heat exchanger and arterial filter cools or warms the blood during extracorporeal circulation. The oxygenator has a blood contacting Cortiva™ -BioActive Surface.

The Affinity NT Hollow Fiber Oxygenator (Affinity NT Oxygenator) is intended to be used in an extracorporeal perfusion circuit to oxygenate and remove carbon dioxide from the blood and to cool or warm the blood during routine cardiopulmonary bypass procedures up to 6 hours in duration.

Affinity NT Oxygenator is designed to be an integral part of the cardiopulmonary heart lung bypass circuit for use during cardiac surgery. Blood that comes from the patient is delivered through a blood pump to the oxygenator and other auxiliary devices, and back to the patient.

The purpose of this 510(k) Notification is to notify the FDA of a labeling change to the disinfectant warning on the Instructions for Use to allow for disinfectant use in the water path of the oxygenator as well as report previous changes for the Affinity NT Oxygenator model included in this submission.

# Indications for Use

There is no change to the intended use of the devices within the scope of the proposed change in this Traditional 510(k) Notification. The current Indications for Use statement for this device is listed below:

The Affinity NT Oxygenator with Cortiva" BioActive Surface is intended to be used in an extracorporeal perfusion circuit to oxygenate and remove carbon dioxide from the blood and to

cool or warm the blood during routine cardiopulmonary bypass (CPB) procedures up to 6 hours in duration.

# Comparison to Predicate Devices

The Affinity NT Oxygenator has the same intended use, design and materials, and principles of operation and technology when compared to the predicate Affinity NT Oxygenator.

- Intended Use: The intended use is the same as the predicate device. ●
- Design: The design is the same as the predicate device. ●
- Materials: The materials of the Affinity NT Oxygenator are the same as the predicate ● device.
- Principles of Operation and Technology: The principles of operation are the same as the ● predicate device.
- Performance: The performance of the device is the same as the predicate device. ●

# Summary of Performance Data

Testing was used to verify the performance characteristics of this device. Clinical testing was not required to establish substantial equivalence. The following performance tests were conducted:

| Testing | Description | Result |
|--------------------|---------------------------------------------------------------------------------|--------|
| Pressure Integrity | Water path must withstand 45 PSI pressure for 6 hours<br>without leaking | Pass |
| Burst | Water path burst testing should be comparable to that of<br>the control devices | Pass |
| Port Break | Water path break force shall be comparable to that of the<br>control device | Pass |

An analysis was also completed to characterize the physical properties of the materials used to construct the water side of the heat exchanger.

#### Conclusion

Medtronic has demonstrated that the modification made to the Affinity NT Oxygenator with Cortiva™ BioActive Surface is substantially equivalent to the predicate devices based upon design, test results, and indications for use.
