Intended Use

The CuffGuard is an endotracheal tube cuff controller designed to continuously monitor and maintain user-defined endotracheal tube cuff pressure for patients (adults and pediatrics) who require mechanical ventilation and who are intubated with endotracheal tube including cuff in the ICU, OR and for intra-hospital transport.

Device Story

CuffGuard is an endotracheal tube cuff controller for ICU, OR, and intra-hospital transport use. Operated by trained physicians or nurses, it continuously monitors and automatically maintains user-defined cuff pressure. The device utilizes a pressure sensor and air pump to adjust cuff pressure via embedded software. It provides visual and audible alarms for leaks or pressure deviations. Output is displayed to the clinician to ensure cuff pressure remains within a safe, user-defined range (5–40 cmH2O), preventing complications associated with improper cuff inflation. The device is portable, powered by battery or AC, and intended for use on adult and pediatric patients.

Clinical Evidence

No clinical or animal studies were conducted. Substantial equivalence is supported by bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), and software verification and validation.

Technological Characteristics

Portable, software-controlled pressure controller. Features: pressure sensor, air pump, visual/audible alarms, battery/AC power. Pressure range: 5–40 cmH2O; control accuracy: +/- 2 cmH2O. Compliant with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, and IEC 60601-1-8. No patient-contact materials.

Indications for Use

Indicated for adult and pediatric patients requiring mechanical ventilation who are intubated with an endotracheal tube. Contraindicated if the endotracheal tube itself is contraindicated.

Regulatory Classification

Identification

An inflatable tracheal tube cuff is a device used to provide an airtight seal between a tracheal tube and a patient's trachea.

Dear Perrine Moelle:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

## 1.2. Indications for use

The CuffGuard is an endotracheal tube cuff controller designed to continuously monitor and maintain user-defined endotracheal tube cuff pressure for patients (adults and pediatrics) who require mechanical ventilation and who are intubated with endotracheal tube including cuff in the ICU, OR and for intra-hospital transport.

The following differences exist between subject and predicate device:

- The subject device is not indicated to be used on tracheostomy tube (TT)
- The subject device is not indicated to be used on neonate population of patient
- The subject device is not indicated to be used during transfer by rescue vehicles, ship, jet or helicopter

However, these differences do not raise questions of safety and effectiveness, because:

- the indication not applicable for the subject device (Tracheostomy tube),
- the population not applicable for the subject device (neonate),
- the environment of use not applicable for the subject device (transfer by rescue vehicles, ship, jet, or helicopter),

are not considered for the comparison.

The subject device and its predicate device are both used in the same clinical conditions or purposes (adult or pediatric patients requiring mechanical ventilation for whom the cuff pressure of an endotracheal tube (ETT) is monitored) and are used by the same kind of users (trained medical professional). They have the same principle of operation, using a pressure sensor and air pump).

## 4. Comparison of technological characteristics with the predicate device

The technological principle of the subject device is to maintain and automatically adjust thanks to embedded software, the cuff pressure of intubating tubes using a pressure sensor and a pump.

The following technological difference exists between subject device and its predicate device:

510(k) – CuffGuard
5-4

{8}

idmed
an eye on your patient

- The pressure range of the subject device is not as wide as its predicate device

However, this difference is supported by performance data (Software verification or safety test reports). Furthermore, this difference does not raise different questions of safety and effectiveness and does not negatively affect the clinical performances for the following reason:

- Difference of pressure range has been evaluated on the SW verification and validation. Furthermore, this difference is not clinically significant as the use of pressure range until 40 cm H2O appears as a realistic physiological limit and as a common clinical practice used as shown on various publications.

# 5. Performance data

The following performance data were provided in support of the substantial equivalence determination.

## Electrical safety and electromagnetic compatibility (EMC)

Electrical safety and EMC testing were conducted on the CuffGuard device. The system complies with the IEC 60601-1, IEC 60601-1-6 and IEC 60601-1-8 standards for safety and the IEC 60601-1-2 standard for EMC.

## Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA’s Guidance for Industry and FDA Staff, “Content of Premarket Submissions for Device Software Functions.” The documentation level for CuffGuard software is enhanced.

## Animal and Clinical Studies

No animal or clinical testing was required to demonstrate the substantial equivalence of this device to its predicate, nor its safety and effectiveness.

# 6. Conclusions

Based on its intended use, design principles, and technological characteristics, the CuffGuard device was found to be as safe, as effective, and performs comparably to the predicate device.

The technological differences identified do not raise new questions of safety and effectiveness as the non-clinical and clinical literature data support the safety of the device and the hardware and software verification and validation demonstrate that the CuffGuard device should perform as intended in the specified use conditions.
