No
The document describes a mechanical peristaltic pump system with electronic controls for monitoring and adjusting speed, flow, and pressure. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes.
The device is used in extracorporeal perfusion circuits to pump blood during cardiopulmonary bypass, which is a therapeutic procedure to support heart and lung function.
No
The device is a blood pump system intended for use in cardiopulmonary bypass procedures, which is a therapeutic function rather than a diagnostic one. While it monitors flow rate, pump speed, and pressure, these are operational parameters for the pump itself, not diagnostic indicators of a patient's condition.
No
The device description explicitly lists multiple hardware components including a console, rotor, holder, chamber, and connecting tube. It also describes the physical mechanism of the peristaltic pump.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "pump blood during routine cardiopulmonary bypass procedures." This is a procedure performed on a patient's body (extracorporeal), not a test performed on a sample taken from a patient's body.
- Device Description: The description details a mechanical pump system designed to move blood in a circuit outside the body. It does not describe any components or functions related to analyzing biological samples.
- Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing diagnostic information based on sample analysis
The device is clearly intended for a therapeutic/supportive function during surgery, not for diagnostic testing.

Device Description
The AVECOR Cardiovascular Affinity Pump System consists of the Model 2000 Affinity Pump Console, Affinity Pump Rotor, Affinity Pump Holder, Affinity Pump Chamber, 5/8" Connecting Tube and an AVECOR venous reservoir with 5/8" outlet. The AVECOR Affinity Pump has been designed to operate on the principles of a peristaltic pump for extracorporeal use. The pump consists of a polyurethane chamber incorporating polycarbonate inlet and outlet connectors, which fills passively due to the filling pressure exhibited by the fluid height in a reservoir. The peristaltic action of the rollers against the filled pump chamber results in forward flow. Flow rate is affected by the combination of reservoir volume, RPM's of the pump rotor and the total circuit resistance.

Summary of Performance Studies
The following tests were conducted by AVECOR to establish the safety and effectiveness of the Affinity Blood Pump System:
- In Vitro Operating Characteristics (Section III)
- In Vitro Cellular Damage (Section III)
- Material Biocompatibility (Section IV)
- Sterility (Section V)
- Pyrogenicity (Section V)
- Sterilant Residuals (Section V)
- Software Validation & Verification (Appendix E)
The results indicate that the Affinity Blood Pump System is substantially equivalent in performance to the Stockert Instrumente (Sorin) Pump System. Blood trauma testing showed equivalence in hemolysis, platelet and white cell response.

- Device Name: Cardiopulmonary Bypass Roller-Type Pumps, Consoles and Bypass Pump Tubing have been classified by the Cardiovascular Device Classification Panel as Class II devices, as proposed in Section 870.4220/4370/4380/4390, Title 21 of the Code of Federal Regulations
- న్. Device Description & Comparison to Predicate Device:
To establish the substantial equivalency of the AVECOR Affinity Pump System to the Stockert Instrumente (Sorin) Pump design, specifications, materials, indications for use, and performance characteristics were compared.
DESIGN
The AVECOR Affinity Blood Pump System is intended for use in an extracorporeal perfusion circuit to pump blood during routine cardiopulmonary bypass procedures up to 6 hours in duration.
The AVECOR Cardiovascular Affinity Pump System consists of the Model 2000 Affinity Pump Console, Affinity Pump Rotor, Affinity Pump Holder, Affinity Pump Chamber, 5/8" Connecting Tube and an AVECOR venous reservoir with 5/8" outlet.
The AVECOR Affinity Blood Pump Console and components' shall conform with all the applicable requirements of IEC 601, UL 544 and will display the European Community CE marking.
The Affinity Pump Console, Model 2000 provides a system for controlling a variable speed pump motor and additional systems for monitoring flow rate, pump speed (RPM), pressure, timed events and battery status.

The AVECOR Affinity Pump has been designed to operate on the principles of a peristaltic pump for extracorporeal use. The pump consists of a polyurethane chamber incorporating polycarbonate inlet and outlet connectors, which fills passively due to the filling pressure exhibited by the fluid height in a reservoir. The peristaltic action of the rollers against the filled pump chamber results in forward flow. Flow rate is affected by the combination of reservoir volume, RPM's of the pump rotor and the total circuit resistance.
The Stockert Instrumente (Sorin) Pump Console Model No. 10-10-00, provides a system for controlling a variable speed pump motor and additional systems for monitoring flow rate, pump speed (RPM), pressure and timed events.
The Stockert Instrumente (Sorin) Pump is designed to operate on the principles of a peristaltic pump for extracorporeal use. The pump consists of a polyvinyl chloride tubing segment with polycarbonate connectors at each end. Flow rate is affected by the RPM's, of the pump rotor, total circuit resistance and the size of the tubing segment used.
