The device description details a galvanic oxygen sensor based on electrochemical principles, with no mention of AI or ML algorithms for data processing or interpretation. The "Mentions AI, DNN, or ML" section explicitly states "Not Found".
No.
The device is described as an oxygen-sensing component in finished medical devices that monitor oxygen concentration, not as a device that delivers therapy itself.
No
Explanation: The device is an oxygen sensor, a component used in medical devices like oxygen monitors and ventilators. Its function is to measure oxygen concentration, which is data used to inform medical decisions, but the sensor itself does not make a diagnosis.
No
The device description clearly outlines physical components like a lead anode, oxygen cathode (made of gold), an aqueous electrolyte solution, a fluoropolymer membrane, and an electronic network (resistors/thermistors). This indicates a hardware-based device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to be an oxygen-sensing component in finished medical devices that monitor oxygen concentration in the patient's breathing environment. This involves analyzing the gas the patient is inhaling or exhaling, not a sample taken from the patient (like blood, urine, or tissue).
- Function: The function is to measure oxygen concentration in finished medical devices like oxygen monitors, analyzers, ventilators, and humidifiers. These devices are used to assess the composition of the air or gas mixture being delivered to or exhaled by the patient.
- Device Description: The description details how the sensor works by measuring the partial pressure of oxygen in a gas in contact with a membrane. This is a measurement of the external environment, not an internal biological sample.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device measures the composition of a gas, which is not a human biological specimen.

Device Description
Ceramatec galvanic oxygen sensors are lead-oxygen batteries consisting of a lead anode and an oxygen cathode. The oxygen cathode is to be made up of gold and an aqueous electrolyte solution. The gold electrode is in close proximity to a non-porous fluoropolymer membrane. Oxygen permeating through the membrane is reduced electrochemically at the gold electrode. An electronic network, consisting of one or more resistors and/or thermistors for temperature compensation, is connected between the cathode and anode which allows the lead-oxygen battery to continually discharge in the presence of oxygen. The said network may reside either within the sensor or be incorporated in an attached analyzer. The current that flows through the device is proportional to the partial pressure of oxygen of the gas in contact with the fluoropolymer membrane. An attached analyzer detects the oxygen concentration by measuring the voltage between the ends of the resistor network.

8.0 Predicate Device:
Seatronics Company, Inc. family of galvanic oxygen sensors.
9.0 Device Function:
Monitor oxygen concentration in the patient environment.
10.0 Method of Operation:
Ceramatec galvanic oxygen sensors are lead-oxygen batteries consisting of a lead anode and an oxygen cathode. The oxygen cathode is to be made up of gold and an aqueous electrolyte solution.
The gold electrode is in close proximity to a non-porous fluoropolymer membrane. Oxygen permeating through the membrane is reduced electrochemically at the gold electrode. An electronic network, consisting of one or more resistors and/or thermistors for temperature compensation, is connected between the cathode and anode which allows the lead-oxygen battery to continually discharge in the presence of oxygen. The said network may reside either within the sensor or be incorporated in an attached analyzer.
The current that flows through the device is proportional to the partial pressure of oxygen of the gas in contact with the fluoropolymer membrane. An attached analyzer detects the oxygen concentration by measuring the voltage between the ends of the resistor network.
The following electrochemical reaction occurs in Ceramatec galvanic oxygen sensors:
| Cathode: | $O_2 + 4e^- \rightarrow 2O^{2-}$ |
|---|---|
| Anode: | $2Pb \rightarrow 2Pb^{2+} + 4e^-$ |
Although a sensor is sealed against electrolyte leakage, it is open to ambient atmosphere so it can detect oxygen. The membrane is chosen to govern gas flow into the sensor to give a good compromise between sensor response and environmental tolerance. A more open membrane may give faster response, but allows ingress of other atmospheric species such as acid vapor and water vapor.
In summary, Ceramatec galvanic oxygen sensors are designed to provide a current output that, at constant temperature and pressure, is linearly proportional to the oxygen partial pressure.
Both the Ceramatec family of galvanic oxygen sensors and the predicate device family operate in the manner described above.

16.0 Conclusion:
In summary, based on the information provided, it has been determined that the Ceramatec, Inc., family of galvanic oxygen sensors is substantially equivalent to the Seatronics Company family of galvanic oxygen sensors and are safe and effective for their intended use.
- MAXCELL 11 is the dual-cathode version of the MAXCELL-1. Otherwise, they are identical and will be treated as one.
CAG-2, CAG-8, and CAG-10 differ only in body shape and electronic connection and are otherwise identical. Therefore, the CAG-2, CAG-8 and the CAG-10 will be treated as one.
CAG-9, CAG-15, CAG-18, and CAG-19 differ only in body shape and electronic connection and are otherwise identical. Therefore they will be treated as one.
CAG 12, CAG 13, and CAG-17 differ only in electronic connection and will therefore be treated as one. " Since the patient breathing environment is a temperature-controlled setting, the galvanic oxygen sensors are not typically used at 0 ℃ to 5 ℃. Therefore, the operating temperature ranges of the Ceramatec family of galvanic oxygen sensors and the Seatronics family of galvanic oxygen sensors are equivalent.
