Yes
The device is described as an autotransfusion device used for processing shed blood to obtain washed packed red blood cells for reinfusion, or for the perioperative separation of blood into Packed Red Cells (PRC), Plasma (PLS), and Platelet Rich Plasma (PRP). These actions directly treat or modify physiological processes, classifying it as a therapeutic device.
No
The device is an autotransfusion system designed for processing shed blood for reinfusion and separating blood components, which are therapeutic and blood processing functions, not diagnostic capabilities.
No
The device description clearly outlines both reusable electromechanical hardware components (centrifuge, pumps, sensors, etc.) and disposable sets, indicating it is a hardware-based system with integrated software, not a software-only device.
Based on the provided information, the Fresenius C.A.T.S (Continuous Autotransfusion System) is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to process autologous shed blood collected intraoperatively and postoperatively to obtain washed packed red blood cells for reinfusion, and for perioperative separation of blood into components. This is a therapeutic or procedural use, not a diagnostic one.
- Device Description: The device is described as an electromechanical system with a centrifuge, pumps, sensors, and disposable sets for processing blood. This aligns with a system designed for physical manipulation and separation of blood components, not for analyzing blood to diagnose a condition.
- Lack of Diagnostic Function: There is no mention of the device performing any tests or analyses on the blood to provide diagnostic information about a patient's health or condition. It's focused on preparing blood for reinfusion or separating it into components.
- Performance Studies: The performance studies mentioned focus on comparing the device's blood processing capabilities and the quality of the processed blood, not on its ability to diagnose or detect specific substances in the blood.
In summary, the C.A.T.S system is a medical device used for processing blood for therapeutic purposes (reinfusion) or for separating blood components. It does not perform diagnostic tests on the blood.

Device Description
The Fresenius C.A.T.S is a continuous autotransfusion system working on the principle of a continuous flow centrifuge. In this continuous system, the blood to be processed passes through a separation chamber that can be divided into several compartments in which different steps of the autotransfusion process (i.e; plasma separation, resuspension with saline and reconcentration) are performed simultaneously, creating a continuous flow of blood through the system. The C.A.T.S device is comprised of two major components:
Reusable Autotransfusion Device: The C.A.T.S machine is an electromechanical a) microprocessor controlled device which incorporate the following major system
components: the user display and function keys, centrifuge housing, centrifuge rotors; blood, packed red cell (PRC) and saline roller pumps; blood, saline and PRC sensors; leakage detector, and power supply unit. Additionally, the system includes the electronic components and system software which control and monitor the blood processing procedure.
b) Disposable AT1 Autotransfusion Set: This disposable set incorporates the continuous washing chamber, adapters for mounting the set into the C.A.T.S device, blood inlet line with stepped adapter, pump tubing, fluid lines; and the waste and reinfusion bags.
In order to perform plasma sequestration procedures a second disposable set is necessary:
c) PSQ Set: a single use, disposable set, includes bags for collection of plasma and platelet concentrates. Additionally, the PSQ Set includes lines/connections for connection to the whole blood bag and connection to the C.A.T.S AT 1 Autotransfusion Set.
In order to perform a plasma sequestration procedure, the PSQ Set is attached to the AT1 Autotransfusion Set. The blood bag is then connected to the blood inlet line of the PSQ Set. Separation/processing is accomplished in the washing chamber of the AT1 Autotransfusion Set.
The plasma sequestration process is accomplished in four phases which are automatically controlled by the C.A.T.S system: Separation or Sequestration Phase (plasma and red blood cell separation and collection), PRC Transfer Phase (collection of residual red blood cells), PRP Transfer Phase (collection of the buffy coat containing platelets and a small volume of plasma) and Plasma Transfer Phase (recovery of the residual plasma remaining in the washing chamber). Following completion of the plasma sequestration process, the operator can either: 1) choose to sequester another unit of blood or 2) discontinue plasma sequestration, remove the PSQ Set and prepare the AT1 Autotransfusion Set for an autotransfusion procedure.
For simplicity of use, the C.A.T.S sequestration procedure has been automated as much as possible; however, between the different phases of component collection, the operator is required to open/close clamps of the respective component lines to direct the fluid flow into the appropriate component bag. This is not unique to the C.A.T.S sequestration program as other autotransfusjon systems indicated for plasma sequestration also require user intervention. In fact, with some systems, such as the Haemonetic's CellSaver 5, the user must visually monitor the red blood cell/buffy coat interface, halt the sequestration process when red blood cells enter the effluent line (by pressing the EMPTY key), and open and close clamps to the respective component lines during operation. Visual monitoring of the red blood cell/buffy coat interface and manual interruption of the plasma sequestration process are not required with the C.A.T.S device.

During plasma sequestration with the C.A.T.S system, the operator may adjust the processing speed within pre-established limits. This can be done without compromising the plasma/platelet recovery rates or the quality of the fractionated components. The centrifuge speed, which is automatically controlled by the system, can not be manually adjusted by the user.
Technological Characteristics of the Subject Device Compared with Predicate Devices
The 510(k) "Substantial Equivalence Decision Making Process (Detailed)" decision tree (ODE Guidance Memo #K86-3) was utilized to make a determination of substantial equivalence. The answers to questions identified on this decision tree lead to a determination of substantial equivalence.
