Intended Use
The A-Med Miniature Centrifugal Blood Pump System is indicated for use in extracorporeal circulatory support systems (for periods up to six hours) not requiring artificial oxygenation (e.g., valvuloplasty, circulatory support during surgery of the vena cava or aorta, liver transplants, etc.). The A-Med Miniature Centrifugal Blood Pump is indicated for use only with the A-Med Blood Pump Controller.
Device Description
The A-MED Miniature Centrifugal Pump is a sterile, disposable, non-roller pump which utilizes a rotor to impart energy to the blood through centrifugal forces. The flow of the miniature pump is "demand responsive" by automatically responding to the resistance against which it is pumping and to the amount of fluid returned to the miniature pump with the appropriate changes in flow and pressure. A drive cable and magnetic coupling are hermetically sealed components of the miniature pump. The A-MED Miniature Centrifugal Pump System includes a motor, ultrasonic flow sensor and a microcomputer-based control console which are available separately. The Miniature pump consists of inner and outer housings containing a rotor which imparts energy to the pumping fluid 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. The shaft of the rotor is constrained by two sets of bearings that allow it to rotate freely. A lip seal is used just behind the rotor to seal fluid from entering into the bearing area. A sheath cable assembly connects the pump to the drive motor. The pump end of the cable has a square drive shaft that is bonded and crimped to the cable. This drive shaft fits into a square opening in the end of the rotor. The other end of the cable is connected to a magnet rotor housed in a plastic shell. This end is assembled onto the motor-stator for operation. By assembling the magnet rotor into the end of the cable-sheath assembly, hermitic sealing of the pumping chamber is obtained. A priming port (valve) is provided on the housing to clear the pump of air before starting circulation. The port is designed to open when a syringe is inserted and seals when the syringe is removed. The pump is designed to be placed in the sterile field and operated from the A-Med remote motor and microcomputer based blood pump controller, located outside the sterile field. The A-Med Centrifugal Pump System also includes an ultrasonic flow meter, manufactured by Transonics, Inc.
More Information

Not Found

No
The description focuses on mechanical and basic electronic control ("microcomputer-based control console") of a centrifugal pump. There is no mention of AI, ML, or any advanced algorithms for data analysis or decision-making beyond basic "demand responsive" flow control based on resistance and fluid return.

Yes

The device is indicated for use in "extracorporeal circulatory support systems" for procedures like "valvuloplasty, circulatory support during surgery of the vena cava or aorta, liver transplants," which are all medical treatments or interventions, thus making it a therapeutic device.

No

Explanation: The device is a blood pump system for extracorporeal circulatory support, which is a therapeutic function, not a diagnostic one. It pumps blood to support circulation during medical procedures.

No

The device description clearly details multiple hardware components including a pump, motor, flow sensor, and control console. While the control console is microcomputer-based, the system is not solely software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is for "extracorporeal circulatory support systems" during surgical procedures. This involves circulating blood outside the body to support the patient's circulation, not for analyzing samples of blood or other bodily fluids to diagnose or monitor a medical condition.
  • Device Description: The description details a mechanical pump system designed to move blood. It describes components like a rotor, bearings, seals, and a control console. There is no mention of reagents, assays, or any components used for analyzing biological samples.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Providing diagnostic information
    • Using reagents or assays
    • Measuring analytes or biomarkers

The device is a medical device used for therapeutic support during surgery, not for in vitro diagnostic testing.

(a)
Nonroller-type cardiopulmonary and circulatory bypass blood pump —(1)Identification. A nonroller-type cardiopulmonary and circulatory bypass blood pump is a prescription device that uses a method other than revolving rollers to pump the blood through an extracorporeal circuit for periods lasting less than 6 hours for the purpose of providing either:(i) Full or partial cardiopulmonary bypass (
i.e., circuit includes an oxygenator) during open surgical procedures on the heart or great vessels; or(ii) Temporary circulatory bypass for diversion of flow around a planned disruption of the circulatory pathway necessary for open surgical procedures on the aorta or vena cava.
(2)
Classification —Class II (special controls). The special controls for this device are:(i) Non-clinical performance testing must perform as intended over the intended duration of use and demonstrate the following: Operating parameters, dynamic blood damage, heat generation, air entrapment, mechanical integrity, and durability/reliability;
(ii) The patient-contacting components of the device must be demonstrated to be biocompatible;
(iii) Sterility and shelf life testing must demonstrate the sterility of patient-contacting components and the shelf life of these components; and
