Intended Use

The CAPIOX® RX Hollow Fiber Oxygenators with/without Hardshell Reservoir are intended to be used to exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of a patient during cardiopulmonary bypass surgery.
The integral heat exchanger is used to warm or cool blood and/or perfusion fluid as it flows through the device.
The (detachable) hardshell reservoir(s) is (are) used to store blood during extra-corporeal circulation from both venous line and the cardiotomy line (via gravity or vacuum assisted venous drainage procedures). 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 reservoir may also be used for Post-Operative Chest Drainage Procedures.
The CAPIOX® RX Oxygenators with/without Hardshell Reservoirs can be used in procedures lasting up to 6 hours.
The CAPIOX® RX15 is for use with patients when the required blood flow rate will not exceed 5.0 L/min when used with a 4 Liter Reservoir; and when the required blood flow rate will not exceed 4.0 L/min when used with a 3 Liter Reservoir).
The CAPIOX® RX25 is for use with patients when the required blood flow rate will not exceed 7.0 L/min.

Device Description

The modified and predicate Capiox® RX device oxygenator utilizes a 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 wound fiber bundle offers the porous membrane surface to sufficiently permit the movement of gases through the walls of the hollow fibers via diffusion.
The modified and predicate Capiox® RX device have an integrated heat exchanger that is comprised of stainless steel encased in a polycarbonate housing. The stainless steel acts as a heat transfer material that permits heat that is generated from a temperature controlled external water bath to transverse across the walls of the stainless steel to effect the necessary temperature change upon circulating blood.
With respect to the filtration of blood, the modified and predicate Capiox® RX Reservoir relies upon mechanical entrapment of particulates and emboli within the filter mesh as a means to remove those particulates from the blood.
The design of the modified and predicate Capiox® RX devices both utilize an integrated oxygenator/heat exchanger module that provides for temperature control of blood as it enters the oxygenation phase. Each of the devices also utilizes a hardshell reservoir that is used to collect and store blood during a cardiopulmonary bypass procedure. The reservoirs each provide filtration of venous and cardiotomy blood as it enters the reservoir.

AI/ML Overview

The document describes a 510(k) premarket notification for a medical device called the "Capiox RX Hollow Fiber Oxygenator with/without Hardshell Reservoir." This particular submission is a "Special 510(k)" due to modifications made to the hardshell reservoir and a change in the plasticizer used in certain PVC tubing.

Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:

Preamble: This 510(k) submission is for modifications to an existing device (Capiox RX Hollow Fiber Oxygenator with/without Hardshell Reservoir, previously cleared under K130333). Therefore, the "acceptance criteria" discussed are primarily focused on demonstrating that the modified device is substantially equivalent to the predicate device and that the changes do not raise new issues of safety or effectiveness. Clinical studies involving patients were explicitly deemed not necessary for this particular submission.


1. Table of Acceptance Criteria and the Reported Device Performance:

The document states that substantial equivalence is demonstrated with several in-vitro performance evaluations. While it doesn't present a table with specific pass/fail criteria and exact numerical results, it does list the types of performance evaluations conducted to ensure the modified device performs comparably to the predicate.

Acceptance Criteria (Performance Evaluations)Reported Device Performance
Air Handling PerformanceNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. The stated intent of flared venous inlet drop tubes is to "help minimize air emboli generation," suggesting this performance aspect was evaluated and improved or maintained.
HemolysisNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluations would demonstrate that the modified device does not cause increased red blood cell damage compared to the predicate.
Venous Reservoir Pressure DropNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure the modifications do not adversely affect blood flow dynamics through the reservoir.
Venous DefoamingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. The reservoir contains a "filter and defoamer to facilitate air bubble removal," and this function was evaluated.
Leak TestingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure the device remains sealed and prevents fluid leakage.
Winged Adapter Circulation TestingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Specifically for the modified 1/4" x 3/8" winged adapter for the RX15 3-Liter Reservoir, ensuring proper circulation.
3-Liter Drainage Cage Dimensional TestingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure the modified drainage cage accommodates the flared venous inlet drop tubes as intended.
Connections TestingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure proper and secure connections of all components.
Package TestingNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure the packaging maintains device integrity and sterility.
Aged EvaluationNot explicitly detailed in numerical results, but implied to meet equivalence to the predicate. Evaluated to ensure the device maintains performance over its expected shelf life.
Overall Conclusion of Substantial Equivalence"Terumo Cardiovascular Systems concludes that the differences between the modified device and the predicate device do not affect the intended use of the device nor do they affect safety and effectiveness of the device when used as labeled." and "It is further concluded that any recognized differences noted during the assessments do not raise new issues of patient/user safety or product effectiveness."

2. Sample Size Used for the Test Set and the Data Provenance:

The document does not specify exact sample sizes for each in-vitro test. It only lists the types of tests conducted. Since these are in-vitro performance evaluations, the "data provenance" would refer to the testing conditions and the specific samples of the device (modified vs. predicate) used in the lab tests. There is no mention of country of origin for data as it's not a clinical study.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts:

This information is not applicable as the document explicitly states: "Clinical studies involving patients are not necessary to demonstrate substantial equivalence of the modified Capiox® RX device to the predicate Capiox® RX device." The testing described is in-vitro performance evaluation, not expert-adjudicated clinical or image-based ground truth.

4. Adjudication Method for the Test Set:

This information is not applicable for the same reason as point 3.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

This information is not applicable. The device is an oxygenator and reservoir system, not an AI-assisted diagnostic or therapeutic tool for human readers. No MRMC study was conducted.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

This information is not applicable. The device is not an algorithm or AI system.

7. The Type of Ground Truth Used:

For this device, the "ground truth" for the in-vitro performance evaluations would be:

  • Engineering specifications and regulatory standards: The tests are designed to demonstrate that the device meets predefined engineering requirements and applicable regulatory standards for blood oxygenators and reservoirs.
  • Performance of the predicate device: The modified device's performance is compared against the established performance of the previously cleared predicate device, aiming for substantial equivalence rather than an absolute ground truth in the sense of a disease diagnosis.

8. The Sample Size for the Training Set:

This information is not applicable as this is not an AI/machine learning device requiring a training set.

9. How the Ground Truth for the Training Set Was Established:

This information is not applicable as this is not an AI/machine learning device.

Device Information

5.3 Intended Use:

The intended use remains the same for the modified device and predicate device.

The CAPIOX® RX Hollow Fiber Oxygenators with/without Hardshell Reservoir are intended to be used to exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of a patient during cardiopulmonary bypass surgery.

The integral heat exchanger is used to warm or cool blood and/or perfusion fluid as it flows through the device.

The (detachable) hardshell reservoir(s) is (are) used to store blood during extra-corporeal circulation from both venous line and the cardiotomy line (via gravity or vacuum assisted venous drainage procedures). 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 reservoir may also be used for Post-Operative Chest Drainage Procedures.

The CAPIOX® RX Oxygenators with/without Hardshell Reservoirs can be used in procedures lasting up to 6 hours.

The CAPIOX® RX15 is for use with patients when the required blood flow rate will not exceed 5.0 L/min when used with a 4 Liter Reservoir; and when the required blood flow rate will not exceed 4.0 L/min when used with a 3 Liter Reservoir).

The CAPIOX® RX25 is for use with patients when the required blood flow rate will not exceed 7.0 L/min.

5.4 Principles of Operation and Technology:

The principles of operation and technology remain the same for the modified device and predicate device.

The modified and predicate Capiox® RX device oxygenator utilizes a 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 wound fiber bundle offers the porous membrane surface to sufficiently permit the movement of gases through the walls of the hollow fibers via diffusion.

The modified and predicate Capiox® RX device have an integrated heat exchanger that is comprised of stainless steel encased in a polycarbonate housing. The stainless steel acts as a heat transfer material that permits heat that is generated from a temperature controlled external water bath to transverse across the walls of the stainless steel to effect the necessary temperature change upon circulating blood.

With respect to the filtration of blood, the modified and predicate Capiox® RX Reservoir relies upon mechanical entrapment of particulates and emboli within the filter mesh as a means to remove those particulates from the blood.

{6}------------------------------------------------

5.5 Design and Materials:

.

The design of the modified and predicate Capiox® RX devices both utilize an integrated oxygenator/heat exchanger module that provides for temperature control of blood as it enters the oxygenation phase. Each of the devices also utilizes a hardshell reservoir that is used to collect and store blood during a cardiopulmonary bypass procedure. The reservoirs each provide filtration of venous and cardiotomy blood as it enters the reservoir.

With respect to the design of the Oxygenator, the modified Capiox® RX Oxygenator device is unaffected by the changes being incorporated at this time. The subject of this Special 510(k) is a modification being made to the Hardshell Reservoir.

Differences in the design of the Capiox® RX devices are as follows:

  • The design of the modified Capiox® RX device will include:
    • flared venous inlet drop tubes o
    • o The RX15 3-Liter Reservoir's drainage cage, that houses the flared venous inlet drop tubes, will be modified
    • A full-length graduated side scale label (decal) o
    • A modified 1/4" x 3/8" winged adapter (adapter is for the RX15 3-Liter Reservoir o only)
  • The intent of the flared venous inlet drop tubes is to help minimize air emboli generation . in the venous section of the reservoir.
  • The intent of the modified RX15 3-Liter Reservoir's drainage cage is to accommodate . the modified flared venous inlet drop tubes.
  • . The full-length graduated side scale label (decal) enhancement offers greater visibility of blood volume during cardiopulmonary bypass.
  • The modified 1/4" x 3/8" winged adapter (adapter for RX15 3-Liter Reservoir only) is ● used to provide attachment to the 1/4" arterial and venous line connections.
  • The design of the predicate Capiox® RX device has: .
    • straight venous inlet drop tubes o
    • The RX15 3-Liter Reservoir's drainage cage is the original size from initial FDA o clearance.
    • A half-length graduated side scale label (decal) O
    • A 1/4" x 3/8" adapter o

Difference in the materials of the Capiox® RX devices are as follows:

  • o The materials used in the construction of the modified Capiox® RX Hollow Fiber Oxygenator with/without Hardshell Reservoir device's venous inlet drop tubes along with the auxiliary drop tube, quick disconnect tubing, sampling manifold tubing, and purge line tubing will be PVC tubing with Tris-(2-Ethylhexyl) Trimellitat, identified as TOTM plasticizer.1
  • . The materials used in the construction of the predicate Capiox® RX Hollow Fiber Oxygenator with/without Hardshell Reservoir device's venous inlet drop tubes along with the auxiliary drop tube, quick disconnect tubing, sampling manifold tubing, and

{7}------------------------------------------------

Device Information

5.5 Design and Materials continued:

  • purge line tubing is PVC tubing with Di-(2-ethylhexyhl) phthalate, identified as DEHP ● plasticizer.
  • The intent of the PVC tubing plasticizer change to TOTM plasticizer is to address o potential safety concerns associated with the use of DEHP as a plasticizer.

The materials used in the construction of the modified and predicate Capiox® RX Hollow Fiber Oxygenator/Hardshell Reservoir devices include, but are not limited to, nylon, polycarbonate, silicone, stainless steel, polyvinyl chloride, polyurethane, polyester, polypropylene, polyethylene and X-Coating™.

Terumo Cardiovascular Systems concludes that the differences between the modified device and the predicate device do not affect the intended use of the device nor do they affect safety and effectiveness of the device when used as labeled.

5.6 Performance Evaluations:

Clinical studies involving patients are not necessary to demonstrate substantial equivalence of the modified Capiox® RX device to the predicate Capiox® RX device. Substantial equivalence is demonstrated with the following in-vitro performance evaluations:

  • Air Handling Performance ●
  • Hemolysis ●
  • Venous Reservoir Pressure Drop .
  • Venous Defoaming ●
  • Leak Testing ●
  • Winged Adapter Circulation Testing .
  • 3-Liter Drainage Cage Dimensional Testing .
  • Connections Testing ●
  • Package Testing ●
  • Aged Evaluation .
