Intended Use
The ESOTEST MULTI Temperature Monitoring System is composed of ESOTEST MULTI Monitor and ESOTEST MULTI Probe and is intended for the continuous detection, measurement and visualization (in °C) of esophageal temperature. The intended environments of use are operating rooms and interventional electrophysiology rooms. The ESOTEST MULTI Monitor must be used in conjunction with the ESOTEST MULTI Probe.
Device Description
The ESOTEST MULTI Temperature Monitoring System is composed of the following device components: - Monitor ESOTEST MULTI MONITOR - Esophageal probe ESOTEST MULTI PROBE - Patient cable ESOTEST MULTI PATIENT CABLE The LCD display of ESOTEST MULTI monitor shows the temperatures detected by the thermocouple sensors located in the probe, which is measuring the temperature of the patient's esophagus. Temperatures are displayed as numeric values and as scrolling plots. The user is able to set the value of an upper alarm threshold and that of a lower alarm threshold. If any measured temperature exceeds the upper alarm threshold or falls below the lower alarm threshold, ESOTEST MULTI monitor immediately emits visual and audible alarm signals. The ESOTEST MULTI esophageal probe has a 7 French body equipped with 11 French sensors and is intended for the detection of esophageal temperature at multiple locations. The probe is connected to the monitor by ESOTEST MULTI patient cable.

No
The device description and performance studies focus on standard temperature measurement and alarm functions, with no mention of AI or ML technologies.

No.
The device is for monitoring and detecting esophageal temperature, not for therapeutic intervention or treatment.

Yes

The device is intended for the continuous detection, measurement, and visualization of esophageal temperature, and can emit alarm signals if temperatures fall outside of set thresholds. This continuous monitoring and alerting function by measuring a physiological parameter in a patient for the purpose of identifying potential medical conditions or changes aligns with the definition of a diagnostic device.

No

The device description explicitly lists hardware components: a monitor, an esophageal probe, and a patient cable. The performance studies also include testing related to hardware, such as electrical safety, EMC, sterilization, and biological evaluation of the probe.

Based on the provided information, the ESOTEST MULTI Temperature Monitoring System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to obtain information for diagnostic or monitoring purposes.
  • ESOTEST MULTI Function: The ESOTEST MULTI system directly measures the temperature of the patient's esophagus in vivo (within the living body). It does not analyze specimens taken from the body.
  • Intended Use: The intended use is for "continuous detection, measurement and visualization (in °C) of esophageal temperature," which is a direct physiological measurement, not an analysis of a biological sample.

Therefore, the ESOTEST MULTI Temperature Monitoring System falls under the category of a medical device that performs a direct physiological measurement, not an In Vitro Diagnostic device.

Substantial Equivalence Discussion

The ESOTEST MULTI Temperature Monitoring System is intended for the same use as the predicate device. The differences between the ESOTEST MULTI Temperature Monitoring System and the predicate device are listed and discussed in the table below:.

DifferenceImpact on safety and effectiveness
ESOTEST MULTI makes use of an external power supply (included in the package of ESOTESTThe adoption of a medical grade external power supply and of a custom locking connector does not introduce new
DifferenceImpact on safety and effectiveness
MULTI monitor)questions of safety and effectiveness. It has been verified by
testing the power supply system together with the device
according to the requirements of the applicable Electrical
Safety standards,
ESOTEST MULTI has a larger measurement rangeThe larger measurement range does not introduce new
questions of safety and effectiveness. It has been verified
though performance accuracy testing.
ESOTEST MULTI probe has 5 to 7 sensors instead
of 3 as the probe of the predicate deviceThe greater number of sensors allows the device to monitor
a longer portion of esophagus temperature and does not
introduce new questions of safety and effectiveness. The
probes were verified through performance testing.
ESOTEST MULTI makes use of a touch screen
user interface instead of employing LED displays
and physical buttons as the predicate deviceThe adoption of an LCD display with adequate size and
brightness, along with the capacitive touch screen. This
does not introduce new questions of safety and
effectiveness.
ESOTEST MULTI has a lower alarm threshold in
addition to the upper alarm threshold of the
predicate deviceThe presence of a second alarm threshold allows the user to
employ the alarm both during heating and cooling
treatments. This does not introduce new questions of safety
and effectiveness. The alarm thresholds were validated
through performance testing and the software was
verified/validated.
ESOTEST MULTI can tolerate a slightly larger
mains supply voltage rangeThis does not introduce new questions of safety and
effectiveness. It has been verified by testing the device in
the mains supply rated voltage range, according to
requirements of applicable Electrical Safety standards
The main unit of ESOTEST MULTI is smaller and
lighter and the interconnection cables are longer
than the corresponding components of the predicate
deviceThe fact that the main unit is smaller and lighter does not
introduce new questions of safety and effectiveness.
ESOTEST MULTI measures and displays the
temperature detected by 5 to 7 sensors instead of 3
as the predicate deviceThe LCD display of the greater number of sensors does not
introduce new questions of safety and effectiveness.

l Response time is defined as the mean value of the measured time intervals associated to temperature increase (tr) or to temperature decrease (tf) necessary to cover the 63.3% of the total temperature excursion.

Substantial Equivalence Conclusion

Differences between the intended use and technological characteristics of the subject device compared to the predicate do not raise different questions of safety and effectiveness. The performance of the device is supported by non-clinical testing and risk management activities. The ESOTEST MULTI Esophageal Temperature Probe and Temperature Monitoring System is Substantially Equivalent (SE) to the ESOTEST Esophageal Temperature Probe and Temperature Monitoring System, cleared under K123361.
