No
The description details a microprocessor-based system for controlling a blood pump, with no mention of AI or ML algorithms for decision-making, control, or analysis.
Yes
Explanation: The device is indicated to pump blood through an extracorporeal bypass circuit for circulatory support, which directly treats a physiological function and provides therapeutic benefit.
No
The device description indicates it is a "blood pumping system" used for "extracorporeal circulatory support." Its primary function is to pump blood through a circuit, and while it involves monitoring, this monitoring is for the operation of the pump itself (motor speed, fluid flow, pressure) rather than for diagnosing a patient's condition.
No
The device description clearly outlines multiple hardware components: Blood Pump, Remote Motor Drive Unit, Control Console, and Ultrasonic Flow Sensor. While software is mentioned as being validated and verified, it is part of a larger hardware system.
Based on the provided text, the Levitronix CentriMag® Extracorporeal Blood Pumping System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to pump blood through an extracorporeal bypass circuit for circulatory support during surgical procedures. This is a direct interaction with the patient's blood outside the body for therapeutic purposes (circulatory support), not for diagnostic testing on the blood.
- Device Description: The description details a system designed to physically move blood, control flow rate, and monitor parameters like speed, flow, and pressure. These are all functions related to mechanical blood pumping and monitoring during a procedure, not analyzing blood components for diagnostic information.
- Lack of Diagnostic Function: There is no mention of the device analyzing blood samples, detecting biomarkers, or providing any information used to diagnose a disease or condition.
- Performance Studies: The performance studies focus on bench testing comparing the pumping characteristics to predicate devices, biocompatibility, sterilization, and EtO residuals. These are all relevant to a device that interacts with blood for mechanical support, not for diagnostic analysis.
In summary, the Levitronix CentriMag® Extracorporeal Blood Pumping System is a medical device used for extracorporeal circulatory support, which is a therapeutic intervention, not a diagnostic test performed on a sample of blood.

Intended Use / Indications for Use
The Levitronix CentriMag® Extracorporeal Blood Pumping System is indicated to pump blood through the extracorporeal bypass circuit for extracorporeal circulatory support for periods appropriate to cardiopulmonary bypass (up to six hours). It is also indicated for use in extracorporeal circulatory support systems (for periods up to six hours) not requiring complete cardiopulmonary bypass (e.g., valvuloplasty, circulatory support during mitral valve reoperation, surgery of the vena cava or aorta, liver transplants etc).

Device Description
System - The Levitronix CentriMag® Extracorporeal Blood Pumping System is a fault-tolerant system comprised of four (4) main assemblies which are available separately:
- Blood Pump
- Remote Motor Drive Unit
- Control Console
- Ultrasonic Flow Sensor
Blood Pump - The Levitronix CentriMag® Extracorporeal Blood Pump is a sterile, single-use, disposable, non-pulsatile, non-roller pump that utilizes a rotor to impart energy to the blood in an extracorporeal circuit through centrifugal forces. The inlet to the pump runs concentric with the axis of the rotor. The outlet of the pump is perpendicular to the inlet and tangent to the outer diameter. Blood enters the pump housing via the pump's inlet port where it makes contact with the rotor. As the rotor turns, energy in the form of pressure and velocity is transferred from the rotor to the blood. The CentriMag® Extracorporeal Blood Pump moves the blood through the circuit at a desired pressure and flow rate by increasing or decreasing the speed of the rotor. This is accomplished by adjusting the speed of the rotor. The pump operates from the Levitronix Remote Motor Drive Unit and microprocessor-based console, located outside the sterile field.
Remote Motor Drive Unit - The CentriMag® Motor Drive Unit is positionable on an IV pole/mast or adjacent to the console using an optional utility post. The Motor Drive Unit holds the disposable blood pump and drives the rotor inside the blood pump.
Control Console - The Levitronix CentriMag Console is a microprocessorbased device, which drives and controls the speed of the blood pump in the extracorporeal circuit. The console also provides monitoring of motor speed, fluid flow, and pressure through the use of alphanumeric display, audible alarms and visible alarms.
Ultrasonic Flow Sensor - The Levitronix CentriMag® Extracorporeal Blood Pumping System includes an ultrasonic flow meter.

E. Intended Use
The Levitronix CentriMag® Extracorporeal Blood Pumping System is indicated to pump blood through the extracorporeal bypass circuit for extracorporeal circulatory support for periods appropriate to cardiopulmonary bypass (up to six hours). It is also indicated for use in extracorporeal circulatory support systems (for periods up to six hours) not requiring complete cardiopulmonary bypass (e.g., valvuloplasty, circulatory support during mitral valve reoperation, surgery of the vena cava or aorta, liver transplants etc).
F. Technological Characteristics
The Levitronix CentriMag® Extracorporeal Blood Pumping System has technological characteristics similar to the predicate devices.
Blood Pump - The Levitronix CentriMag® Extracorporeal Blood Pump consists of iniection-molded polycarbonate inner and outer housings containing an injection-molded polycarbonate rotor, which imparts energy to the pumping fluid through centrifyaal forces. The ioints are bonded with an ultraviolet light cured adhesive. The inlet port (3/8") is located at the top center of the pump and the fluid inflow runs concentric with the axis of the rotor. The outlet port (3/8") of the pump is perpendicular to the inlet and tangent to the outer diameter. The rotor contains a magnet that is hermetically sealed. The Levitronix CentriMag® Extracorporeal Blood Pump is designed to be used only with Levitronix CentriMag® Console.
An ultrasonic flow meter is provided to monitor the pump output. Optional pressure transducers are available to monitor inlet/outlet pressures.
Remote Motor Drive Unit - The Motor Drive Unit turns a magnet that is hermetically sealed in the pump's rotor at a speed that is set by the console operator. Three bayonet sockets are provided on the top of the Motor allowing coupling and mounting of the disposable blood pump in three angular directions (90 degrees apart) of the pump outlet. An array of hall sensors in the motor is used to determine motor speed.
3
Control Console - The Levitronix CentriMag Console is a microprocessorbased device. The microprocessor generates the primary motor control signal, monitors system sensors, generates front display outputs, and provides alarm functions. The microprocessor acquires the sensor data for use in generating operator displays and alarms. An alphanumeric screen is used to display monitored data, system options, and menus. Operator settable alarms and parameters are accessible via the system menus.
The CentriMag® console operates off of single phase AC power and is capable of flow rate of up to 9.99 LPM against a maximum pressure head of 600 mmHq. In addition each contains an internal battery that is capable of running the pump for a minimum of 60 minutes when fully charged at maximum speed of 5,500 and under nominal load in the event of a loss of AC Power.
Ultrasonic Flow Sensor - The Flow Sensor is a reusable, non-patient contacting ultrasonic flow sensor which can detect flows from 0-9.99 LPM and can detect retrograde flow of >40 cc/min. This sensor is compatible with 3/8" ID by 3/32" wall tubing.
