The device description explicitly states that the device consists of hardware components including a multi-channel touch screen display, preamplifier, cables, and a single use sensor, in addition to utilizing near infrared diffuse reflectance spectroscopy technology.
Based on the provided information, the INVOS™ Patient Monitor, model PM7100, is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use describes the device as a "noninvasive cerebral/somatic oximetry system intended for use as an adjunct monitor of regional hemoglobin oxygen saturation of blood in the brain or in other tissue beneath the sensor." This involves measuring physiological parameters directly from the patient's body.
- Device Description: The device description details a system that uses near infrared light applied to the skin to measure oxygen saturation in tissue. This is a non-invasive method applied to the living body.
- Lack of In Vitro Activity: An IVD device is specifically designed to examine specimens derived from the human body (like blood, urine, tissue samples) outside of the body to provide information about a physiological state, disease, or condition. The INVOS™ system does not process or analyze samples in vitro.
The INVOS™ system is a non-invasive physiological monitoring device that measures parameters directly from the patient's body.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
NONCLINICAL TESTING:
The INVOS™ PM7100 Patient Monitor was designed and bench tested against the performance categories noted below. When available, the applicable standards and guidance documents were used for design and testing in support of substantial equivalence.
Bench Test Categories: Essential Performance, Electrical Safety, Electromagnetic Compatibility, Usability, Alarm, Optical Safety, Software, Biocompatibility, Mechanical and Environmental, Cybersecurity.
CLINICAL TESTING:
Three clinical studies were conducted and completed: rSO2 trend equivalence, sensor backward compatibility and sensor on/off.
- An rSO2 trend equivalence clinical study was performed to demonstrate the rSO2 trend precision between the INVOS™ PM7100 and the predicate device. A secondary analysis of the data for the system comparison of accuracy and precision to support device equivalency was conducted and demonstrated that rSO2 values of subject and predicate are comparable.
- A sensor backwards compatibility clinical test was performed to demonstrate that the new PMSENS71-A sensor trend accuracy is equivalent to the trend accuracy of the SAFB-SM sensor when used with the INVOS™ 5100C. A secondary analysis of the system comparison of accuracy and precision to support PMSENS71-A sensor equivalency was conducted and demonstrated that rSO2 values of both sensors are comparable.
- A sensor on/off detection clinical study was conducted to demonstrate that the new sensor and the new sensor on/off algorithm are capable of detecting sensor off conditions on clinical study subjects.
Key results:
The clinical studies paired with a bench study using simulated patient data demonstrate that the INVOS™ PM7100 Patient Monitor meets the same trend performance as the predicate device, the new sensor on/off feature functions as intended, and the new sensor is backwards compatible with the predicate device and is therefore deemed substantially equivalent to the predicate device.

INDICATIONS FOR USE:
The INVOS™ Patient Monitor, model PM7100, is a noninvasive cerebral/somatic oximetry system intended for use as an adjunct monitor of regional hemoglobin oxygen saturation of blood in the brain or in other tissue beneath the sensor. It is intended for use on individuals greater than 40 kg at risk for reduced-flow or no-flow ischemic states.
The INVOS™ Adult rSO2 Sensor is indicated for single patient use when cerebral/somatic monitoring of site-specific regional oxygen saturation (rSO2) is required in patients weighing > 40 kilograms. This sensor is only intended to be used with INVOS™ Near Infrared Spectroscopy (NIRS) technology including monitoring systems and devices integrated with INVOS™ NIRS technology. For additional information regarding setup and use of the INVOS™ System including indications for use, contraindications, warnings and cautions, consult the Monitoring System Operator's Manual.
CONTRAINDICATIONS
The INVOS™ Adult rSO2 sensor is contraindicated for use on patients who exhibit allergic reactions to the adhesive tape.
TECHNOLOGICAL CHARACTERISTICS SUMMARY:
The INVOS™ PM7100 Patient Monitor is a four wavelength, diffuse reflectance spectroscopy system employing near infrared light. Two wavelengths of near infrared light are used to estimate the percentage of hemoglobin saturated with oxygen in tissue underneath the sensor and two additional wavelengths are used for sensor on/off detection. An adhesive sensor containing four LED light sources and two photodiodes is applied to the skin over cerebral and somatic tissue and the returning light from two LEDs is analyzed for oxyhemoglobin and deoxyhemoglobin light absorption signals from the photodiode closer to the light source are subtracted from the farther photodiode where the returning photons penetrate more deeply in the tissue. This removes the impact of absorption events originating in the outer layers of tissue that are common to both photodiodes, including the effects of skin pigmentation and subcutaneous tissues.
SUBSTANTIAL EQUIVALENCE STATEMENT:
5
The INVOS™ PM7100 Patient Monitor has the same intended use and indications for the adult population > 40 kg, principles of operation and technological characteristics as the predicate device. The changes in the display, preamplifier and senor do not raise any new questions of safety or effectiveness. Performance data demonstrates that the INVOS™ PM7100 Patient Monitor and the INVOS™ Adult rSO₂ Sensor are equivalent to the predicate.

CLINICAL TESTING:
Three clinical studies were conducted and completed, rSO2 trend equivalence, sensor backward compatibility and sensor on/off in support the INVOS™ PM7100 Patient Monitor.
An rSOz trend equivalence clinical study was performed to demonstrate the rSO2 trend precision between the INVOS™ PM7100 and the predicate device. A secondary analysis of the data for the system comparison of accuracy and precision to support device equivalency was conducted and demonstrated that rSO2 values of subject and predicate are comparable. The INVOS™ PM7100 maintains the same fundamental rSO2 technology as its predicate i.e., the same rSO2 algorithm and the same optical and
6
electrical signal chain.
A sensor backwards compatibility clinical test was performed to demonstrate that the new PMSENS71-A sensor trend accuracy is equivalent to the trend accuracy of the SAFB-SM sensor when used with the INVOS™ 5100C. A secondary analysis of the system comparison of accuracy and precision to support PMSENS71-A sensor equivalency was conducted and demonstrated that rSO2 values of both sensors are comparable. The test supports the use of the PMSENS71-A sensor with the INVOS™ 5100C.
A sensor on/off detection clinical study was conducted to demonstrate that the new sensor and the new sensor on/off algorithm are capable of detecting sensor off conditions on clinical study subjects.
The clinical studies paired with a bench study using simulated patient data demonstrate that the INVOS™ PM7100 Patient Monitor meets the same trend performance as the predicate device, the new sensor on/off feature functions as intended, and the new sensor is backwards compatible with the predicate device and is therefore deemed substantially equivalent to the predicate device.
CONCLUSION
Results from comprehensive verification and validation testing of a system design analysis, a bench-top tissue phantom test, trend performance validation clinical study, and a backward compatibility validation clinical study demonstrated that the INVOS™ PM7100 Patient Monitor is substantially equivalent to the predicate device with respect to clinical use case, characteristics, and performance. This equivalence allows for the subject device to support the same claims (adult only) and indications for use as the predicate device.
The result from the sensor on/off clinical study proves that the INVOS™ PM7100 Patient Monitor can effectively detect when the sensor is on and when the sensor is off the patient.
The results from the human factors validation have shown that the updated monitor/user interface with a touch screen display improves user-friendliness of the system but doesn't introduce unforeseen risk to the subject device.
The information provided in this 510(k) demonstrates the INVOS™ PM7100 Patient Monitor is substantially equivalent to the predicate device with respect to performance.
