Indications for Use
The 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 Story
CentriMag Acute Circulatory Support System provides temporary mechanical circulatory support; used during cardiopulmonary bypass or other extracorporeal circulatory support procedures. System components: primary console, motor, blood pump, flow probe. Motor uses Full MagLev technology to drive pump impeller; rotation creates pressure gradient, moving blood from inflow to outflow port. User sets pump speed via console. Device used in clinical settings (e.g., OR); operated by healthcare professionals. Output (blood flow) assists hemodynamics in patients with acute compromise. Redesign focuses on motor cable with enhanced bend protection to improve durability, flexibility, and reduce risk of cable breaks/short circuits.
Clinical Evidence
No clinical data. Bench testing only. Mechanical performance verification included motor cable endurance testing and kink testing under simulated severe handling to compare the redesigned cable against the predicate design. Compliance with IEC 60601-1 confirmed.
Technological Characteristics
CentriMag Motor uses Full MagLev technology for impeller rotation. System includes primary console, motor, blood pump, and flow probe. Redesign involves motor cable assembly with extended bend protection. Complies with IEC 60601-1. No changes to materials or fundamental sensing/actuation principles.
Indications for Use
Indicated for patients requiring extracorporeal circulatory support during cardiopulmonary bypass or other procedures not requiring complete bypass (e.g., valvuloplasty, mitral valve reoperation, vena cava/aorta surgery, liver transplants) for up to six hours.
Regulatory Classification
Identification

## C. Legally Marketed Predicate Device
CentriMag Extracorporeal Blood Pumping System (K020271) — Original blood pumping system with 1st generation Primary console and Back-up console.
CentriMag 2nd Generation Primary Console and Mag Monitor (K102129) -Redesigned (2nd generation) console and new peripheral monitor introduced.
# D. Device Description
The CentriMag™ Circulatory Support System, hereafter referred to as the CentriMag System, was designed to provide temporary mechanical circulatory support. To date, the CentriMag system in the United States (US) is indicated as a component of an extracorporeal bypass circulatory support circuit for use during cardiopulmonary bypass (CPB) surgery (up to 6 hours). The CentriMag System provides circulatory assistance for patients in acute hemodynamic compromise, a population whose treatment options are limited.
The CentriMag System is composed of:
- CentriMag Primary Console
- CentriMag Motor
- CentriMag Blood Pump
- CentriMag Flow Probe
- Mag Monitor (optional, not shown)

## CentriMag Console
Image /page/4/Picture/20 description: The image shows a gray and black flow sensor with a gray cable attached to it. The sensor has a gray top with a blue arrow and some text on it. The sensor is designed to clamp onto a pipe or tube to measure the flow of liquid or gas.
Flow Probe (fits standard 3/8" tubing)
{5}------------------------------------------------
The CentriMag Motor is a reusable, non-sterile component of the CentriMag Acute Circulatory Support System. The CentriMag Motor holds the blood pump and drives the impeller inside the blood pump. The motor turns the magnet (and impeller) within the blood pump (Full MagLev™ technology) at a speed that is set on the console by the user. When the impeller is rotated, a pressure gradient develops between the center and outside edge of the pump, causing blood to flow from the inflow to the outflow port of the pump. The amount of flow through the pump depends on the speed of the impeller, and the difference between the inlet and outlet pressures.
#### نن Intended Use
The CentriMag Motor is intended for use only with the CentriMag Acute Circulatory Support System. The CentriMag 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 technological characteristics of the CentriMag Acute Circulatory Support System have not changed. The redesigned CentriMag Motor cable with enhanced (longer) bend protection is the focus of this special 510(k) notification. The fundamental technological and functional characteristics of the motor and its cable are the same as the predicate device motor cable.
## G. Comparison to Predicate Device
The redesigned CentriMag Motor cable assembly with longer bend protection has indication for use, technological characteristics, and performance an characteristics which are substantially equivalent to the predicate CentriMag Motor cable. Due to this, the redesigned CentriMag Motor cable structure with enhanced bend protection raises no new safety or effectiveness concerns. These design modifications enhance cable flexibility and durability, and reduce the impact of rough handling and the occurrence of cable breaks and short circuiting.
No other components of the CentriMag Acute Circulatory Support System are affected by the design changes proposed in this Special 510(k) premarket notification.
{6}------------------------------------------------
### H. Summary of Performance Data
Comparison bench testing was performed to evaluate the mechanical performance characteristics of the redesigned CentriMag Motor cable with new bend protection with those of the current motor cable design.
The following mechanical performance verification tests were conducted on both designs:
### Motor Cable Endurance Test:
Evaluated the durability and functionality of the Motor cable and new bend protection assembly under simulated severe handling to demonstrate the new design meets the expected service life of the CentriMag Motor under worst-case conditions. In addition, visual inspection of the test bend area showed the integrity of the outer surface of the motor cable or bend protection in the area of bending.
### Motor Cable Kink Test:
Verified the Motor cable with new bend protection can tolerate excessive kinking or bending with small radius (e.g. when the cable is wound around the housing for storage) for the targeted expected service life. Visual inspection showed no defects on the surface of the motor cable or bend protection in the area of bending.
The redesigned CentriMag Motor cable with new custom-made bend protection successfully passed the cable endurance (bend) and kink test protocols, both designed to represent extreme / severe handling scenarios. The redesigned robust motor cable with extended bend relief successfully passed both tests (no failures), whereas the original cable design was less robust under high stress. Therefore, the redesigned CentriMag Motor cable with new bend protection performance test results demonstrate it to be substantially equivalence to the performance of the predicate CentriMag Motor cable design. Therefore, it can be concluded that the redesigned Motor cable offers enhanced cable flexibility and durability and improved protection from bending and kinking at the bend protection over the current commercial cable design.
Compliance to IEC 60601-1, Medical electrical equipment, Part 1: General requirements for basic safety and essential performance for the redesigned CentriMag Motor cable and new bend protection assembly has been confirmed, and it is therefore, substantially equivalent.
Given the nature of the proposed change, pre-clinical in-vivo testing, biocompatibility, software or sterility testing was not necessary.
No other device components of the CentriMag Motor assembly, or of the CentriMag Circulatory Support System, are affected by the design changes proposed in this Special 510(k) premarket notification.
{7}------------------------------------------------
# I. Clinical Performance
Clinical testing was not performed on the redesigned motor cable.
# J. Conclusion
The redesigned CentriMag Motor cable is substantially equivalent to the predicate CentriMag System motor cable.
