The description mentions "proprietary algorithms" and "analyzed by Medwave's proprietary algorithms," but there is no mention of AI, ML, or related terms like neural networks or deep learning. The algorithms are described as applying a set of coefficients to extracted parameters, which is a traditional algorithmic approach, not indicative of AI/ML.
No.
A therapeutic device is one that treats or prevents a disease or condition, and this device is for monitoring purposes only.
No
Explanation: The device is described as a "non-invasive blood pressure monitor" and its intended use is to "continually monitor systolic, diastolic and mean blood pressure and pulse rate," as well as oxygen saturation and body temperature with optional modules. Monitoring vital signs is generally considered part of patient management and often provides information for diagnosis, but the device itself is a measurement tool not explicitly stated to provide a diagnosis.
No
The device description explicitly mentions a "pressure sensor placed directly on top of the radial artery" and a "patented 'sweep technique' which applies a varying force on the radial artery." These are hardware components and physical interactions with the patient, indicating it is not a software-only device.
Based on the provided information, the Fusion™ System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
- Fusion™ System Function: The Fusion™ System is a non-invasive blood pressure monitor that measures physiological parameters (blood pressure and pulse rate) directly from the patient's body using a sensor placed on the radial artery. It also has options for pulse oximetry and temperature measurement, which are also non-invasive measurements taken directly from the patient.
- No Specimen Analysis: The device does not analyze any specimens taken from the body.
Therefore, the Fusion™ System falls under the category of a non-invasive physiological monitoring device, not an IVD.

Device Description
The Fusion™ System is a non-invasive blood pressure monitor that uses a pressure sensor placed directly on top of the radial artery. This sensor is noninvasive and eliminates the need for an occlusive inflatable cuff. This device is intended to be used on patients by trained medical personnel to continually monitor systolic, diastolic and mean blood pressure, and pulse rate.
The Fusion™ System uses a patented "sweep technique" which applies a varying force on the radial artery. The counterpressure in the artery produces a signal which is digitized and used to calculate blood pressure parameters.
The sensor measures the pulse at the point of maximum energy transfer; the wave shapes are analyzed by Medwave's proprietary algorithms. Parameters are extracted from the waveforms and a set of coefficients are applied to them yielding systolic, mean, and diastolic pressures approximately every 15 heart beats. These algorithms have been tested and validated in clinical studies by synchronized comparisons to arterial line pressure waveforms.
Patient pressures can be monitored visually by viewing the screen and audibly entering limits into the Fusion™ System alarm menu. Patient measurements above or below the limits will be automatically brought to the attention of the caregiver through these visual and audible alarms. A Start/Stop key provides the operator with an option to cancel operation at anytime.
The Fusion™ System can be ordered with additional module options:
- · Tyco Healthcare Nellcor OxiMax Pulse Oximetry System (K012891) provides monitoring of a patient's functional oxygen saturation of arterial hemoglobin.
- · Kendall Genius Thermometer (K920713) provides patient's body temperature readings.
- · Seiko Thermal Printer SII providing hardcopy of readings selected to print.

A.6 Technological Characteristics, Comparison to Predicate Device.
Like the predicate device, the Fusion™ System is a non-invasive blood pressure monitor, which uses a pressure sensor placed on the wrist over the radial artery. This device is intended to be used on patients by trained medical personnel to continually monitor systolic, diastolic and mean blood pressure and pulse rate. The information from this device is intended to guide clinicians in the therapeutic management of their patients by: providing accurate and frequently updated blood pressure information in a safe, noninvasive, easily obtained, and comfortable manner. Both the devices measure the diastolic, systolic blood pressure and pulse rate from the wrist using oscillometric methods. Both the devices are microcomputer controlled.
Like the Vasotrac® System (K011152), the Fusion™ System have a memory function that retains approximately 900 readings.
Like the Vasotrac® System (K011152), the Fusion™ System display systolic, diastolic blood pressures ranging from 40 and 240 mmHg. Both systems have a blood pressure measurement accuracy of a mean difference of ± 5mmHg or less with a standard deviation of 8mmHg or less. The pulse measurement range is the same for both the Vasotrac® System (K011152) and the Fusion™ System, from 40 - 200 bpm. The accuracy of the pulse measurements are + 5 bpm or 10% of the measured pulse frequency.
(Supported by study results in the supporting Clinical Data on file at Medwave, Inc.)
Both Vasotrac® System (K011152) and the Fusion™ utilize the application of pressure to the artery (by the sensor); the counter pressure in the artery produces a pressure waveform. When maximum amplitude is achieved, mean blood pressure is calculated. The Vasotrac® System (K011152) and the Fusion™ System use a unique "sweep" technique for applying pressure to a the radial artery: downward pressure is applied by the sensor to the radial artery at a rate of ~10mmHg per heart beat increasing as the beat amplitude increases and decreasing rapidly when the beat amplitude begins to decrease. A curve fit is made using the amplitude of each beat versus the hold down pressure to form the bell shaped curve. This curve fit is used to determine the true peak that might occur between pulses as well as to filter out small variations due to artifacts or aberrancies.
Both the Vasotrac® System (K01152) and the Fusion™ System utilize Medwave's proprietary algorithms in analyzing the pressure waveforms to calculate the systolic, mean and diastolic readings. Parameters are extracted from the waveforms and a set of coefficients is applied to them, yielding systolic, mean and diastolic pressures. The algorithms have been tested against intra arterial line pressure waveforms and proven to meet industry standards set by the American Medical Instrumentation (AAMI), mean difference of + 5mmHg or less with a standard deviation of 8mmHg or less. (Supported by study results in the Clinical Data on file at Medwave, Inc.)

The Vasotrac® System (K011152) and the Fusion™ System software are identical with the exception of insignificant features incorporated.
The Vasotrac System (K011152), as the Fusion™ System, has a power switch and a LCD display. The operating environment of 100C - 40°C and 10% to 90% relative humidity.
The Fusion™ and the predicate device - the Vasotrac® APM205A Noninvasive Blood Pressure Measurement System (K011152) use the same non-invasive blood pressure measurement accessories.
Any minor differences in the appearance, technology, or manufacture of the predicate device and the Fusion™ System do not raise any new questions of safety or effectiveness. Associated risks posed by the Fusion™ System are thought to be no more than those of well-designed automated cuff-based noninvasive blood pressure devices currently marketed in the interstate commerce are. Both the device and the sensor have been designed to minimize the risk to patients from burns, excessive pressure or sensor failure caused by either normal device use by patient and/or clinical abuse.
