Modifications from predicate include improved user interface and enhanced overspeed protection circuit with component failure detection. Output allows clinicians to maintain extracorporeal circulation; benefits patient by providing controlled, reliable blood flow during bypass. ## Clinical Evidence No clinical testing was performed. Evidence is based on bench testing of functional and user interface specifications. ## Technological Characteristics Peristaltic roller pump; accommodates PVC and silicone rubber tubing (1/8" to 5/8" ID). Features membrane switch interface, digital displays, and overspeed protection circuit. Connectivity includes master/slave synchronization and integration with external controllers (CPC, AEPS). Powered by internal supply. Software-controlled speed set-point circuitry with safety monitoring. ## Regulatory Identification A roller-type cardiopulmonary bypass blood pump is a device that uses a revolving roller mechanism to pump the blood through the cardiopulmonary bypass circuit during bypass surgery. ## Predicate Devices - COBE Precision Blood Pump ## Reference Devices - COBE Computerized Perfusion Controller (CPC) - COBE Air Emboli Protection System (AEPS) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Armstrong Phone: (303) 467-6521 Fax: (303) 467-6525 DATE PREPARED: March 31, 1997 DEVICE TRADE NAME: COBE® Century™ Perfusion Pump COMMON NAME: Peristaltic perfusion blood pump CLASSIFICATION NAME: Roller-type cardiopulmonary bypass blood pump and Cardiopulmonary bypass heart-lung machine console PREDICATE DEVICE: COBE Precision Blood Pump DEVICE DESCRIPTION: The COBE Century Perfusion Pump is the principal component of the COBE Century Perfusion System. It is a peristaltic-type roller pump that functions by tube-occluding rollers that move along a piece of tubing. As the pump head rotates, the rollers draw fluid through the tubing. Pumped fluids are contained within the tubing and have no contact with the pump. The pump has positive displacement over a wide range of flow rates and delivery pressures. The COBE Century Perfusion Pump consists of: - a front panel containing displays and operational switches - a pump head with the roller pump mechanism and shields - a chassis containing control cards, a power supply, and connectors for external devices COBE® is a registered name of COBE Laboratories, Inc. Century™ is a trademark of COBE Laboratories, Inc. {1} # INDICATIONS FOR USE: The COBE Century Perfusion Pump is intended for use in cardiopulmonary surgical procedures requiring pumping of fluids in an extracorporeal circuit for periods up to 6 hours. # TECHNOLOGICAL CHARACTERISTICS: The COBE Century Perfusion Pump is a modification of its predicate, the COBE Precision Blood Pump. As such, it retains most of the technological characteristics of its predicate. Through software and hardware modifications, the pump has an improved user interface and an improved overspeed protection circuit. Updating of the user interface involved replacing most of the rotary switches with membrane switches, replacing the front panel that holds the switches, and providing additional displays. Improving the overspeed protection circuit involved increasing overspeed sensitivity at low speeds, adding a fixed, maximum speed limit, and implementing a safety function which detects a component failure in the speed set-point circuitry. The COBE Century Perfusion Pump and its predicate are equipped with universal tubing clamps, which allow the pumps to accommodate a wide range of tubing sizes and types with a minimum of hardware changes. For non-continuous pumping applications only, polyvinylchloride (PVC) tubing of 1/8 inch to 1/4 inch inside diameter (ID) by 1/16 inch wall minimum can be accommodated. For continuous pumping, PVC tubing of 1/4 inch (ID) by 3/32 inch wall to 5/8 inch ID by 1/8 inch wall can be accommodated. For continuous and non-continuous pumping, silicone rubber tubing with 3/16 inch ID by 1/16 inch wall to 5/8 inch ID by 1/8 inch wall can be accommodated. Flow rate (Liters Per Minute) through the pumps is based on pump speed (Revolutions Per Minute) and tubing ID. Flow rates can range from .01 LPM (3/16 inch ID and 1 RPM) to over 10 LPM (for larger sizes of tubing and higher speeds). For some sizes of tubing, two segments of tubing can be placed in the pump head at the same time. The COBE Century Perfusion Pump is not—nor is it intended to be—interchangeable with its predecessor, the COBE Precision Blood Pump. However, the COBE Century Perfusion Pump and its predicate device are each compatible with certain other devices: 1) The COBE Century Perfusion Pump can be run in master/slave mode with another COBE Century Perfusion Pump. Similarly, the COBE Precision Blood Pump can be run in master/slave mode with another COBE Decision Blood Pump. 2) The COBE Century Perfusion Pump can be operated in conjunction with the COBE Computerized Perfusion Controller (CPC). Similarly, the COBE Precision Blood Pump can be operated in conjunction with the COBE Computerized Perfusion Controller (CPC). The CPC can be used to pressure-limit either pump, volumetrically control either pump, and/or pulse either pump. 3) The COBE Century {2} Perfusion Pump can be used with the COBE Air Emboli Protection System (AEPS). Similarly, the COBE Precision Blood Pump can be used with the COBE Air Emboli Protection System (AEPS). The AEPS is designed to provide protection against air embolism during cardiopulmonary bypass surgery by stopping the pump if specific conditions are sensed. ## NONCLINICAL TEST RESULTS: The COBE Century Perfusion Pump was tested to assure that it met its functional specifications and its user interface specification. It successfully met all specifications at the system test level, where every system requirement was addressed by a corresponding test or tests. ## CLINICAL TEST RESULTS: No clinical testing was performed. ## CONCLUSIONS: The COBE Century Perfusion Pump is a modification of the COBE Precision Blood Pump. Through hardware and software modifications, the Century Perfusion Pump has an improved user interface and an improved overspeed protection circuit. The COBE Century Perfusion Pump is substantially equivalent to the COBE Precision Blood Pump. {3} DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 Ms. Mary L.
