The BPM probe is attached to Shunt Sensors, the HSAT probe is attached to Cuvette(s) during a CPB case for blood parameters measurement during monitoring. Disposable Gas Bottles (Gas 1 & Gas 2) are used with the Calibrator.

The CDI OneView Monitoring System uses the following measurement technologies:

- Optical fluorescence technology to measure partial pressure of oxygen and . carbon dioxide, pH and potassium ion concentration.
- . Optical reflectance technology to measure oxygen saturation, hematocrit, and hemoglobin within the blood.
- Thermistor (resistive) sensing technology to measure blood temperature. ●
- Non-invasive acoustical sensing technology to measure blood flowrate. ●

The CDI OneView Monitoring System measures blood parameters in real time by utilizing a microprocessor-based core, electro-optics modules (i.e., BPM and H/S probe), flow probe (includes flow module and flow sensor), fluorescence chemistry technology, optical reflectance technology and non-invasive acoustical sensing technology. The electro-optics modules connect the core to the disposables (i.e., shunt sensor or cuvette) which are inserted into the extracorporeal circuit. The flow module connects the core to the flow sensor that use clamp-on mechanism to fit around tubing of the extracorporeal circuit. Light is emitted from the modules, optical responses from the blood and the Ultrasonic/acoustical generated signal measurements via the sensor(s) are measured by the core. The blood parameters are measured or calculated by the CDI OneView Processing Core in real time and displayed to the user via a Touchscreen Display.

#### VI. Comparison of Intended Use/Indications to the Predicate Device

The subject and the predicate device have the same intended use as both devices are intended to provide continuous, in-line monitoring of various patient parameters contained within the extracorporeal perfusion circuit and patient during cardiopulmonary bypass procedures.

The subject device indication statement has following changes:

- Blood Flow Rate (Q) as new measured parameter. ●
- Oxygen Extraction Ration (O2ER) and Cardiac Index (CI) as additional . calculated parameters.
- . Cerebral regional oxygen saturation as additional acquired parameter acquired from Cerebral Oximetry Device.

These differences do not alter the intended therapeutic use of the device, nor do they affect the safety and effectiveness of the device relative to the predicate.

These changes are best analyzed through potential differences in Technological Characteristics that are summarized in section below.

Image /page/7/Picture/4 description: The image shows the Terumo logo. The logo consists of a red swoosh above the word "TERUMO" in green, block letters. The logo is simple and modern, and the colors are bright and eye-catching.

{8}------------------------------------------------

The only new measured characteristic added to the subject device that is not included in the predicate device is a flowrate sensor. The addition of flow rate does not add any additional issues of safety and effectiveness, as the previous capability to enter or acquire flowrate is now by direct measurement, known to be more accurate and timelier, and available to the clinician in multiple locations on the extra-corporeal circuit. Internal risk analysis conducted by Terumo Cardiovascular has shown that the clinical use of the flow meter adds no additional risk to the system and generates no new sources of patient harm. Directly measured blood flow rate does not change the risk profile of the device compared to the blood flow rate of the predicate device, as flow rate measurements have substantially similar hazardous situations resulting in equivalent harms. The flow rate measurement data is utilized by the clinician for the same purpose as other measurement parameters (namely optimizing treatment), utilizes the same interface, within the same sequences of events.

#### VIII. Performance Data

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

# Electrical Safety and Electromagnetic Compatibility (EMC)

Evaluation for electrical safety and EMC testing was conducted on the CDI OneView Monitoring System. The CDI OneView Monitoring System complies with the IEC 60601-1 standard for electrical safety and the IEC 60601-1-2 standard for EMC.

# Software Verification and Validation Testing

Software verification and validation testing was completed successfully. The fulfillment documentation is provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for CDI OneView Monitoring System is considered a "moderate" level of concern since a malfunction or latent design flaw of the software device could lead to an erroneous diagnosis or a delay in delivery of appropriate medical care that would likely lead to minor injury.

# Design Verification and Validation Testing

Design verification testing was conducted and demonstrates that the CDI OneView Monitoring System performs pursuant to the defined design input requirements for the subject device. Design validation, including simulated use testing, was conducted and demonstrates that the CDI OneView Monitoring System meets the defined design input requirements for the subject device.
