Indications for Use
The CATSmart (Continuous Autotransfusion System) device by Fresenius Kabi is an autotransfusion device indicated for the processing of autologous shed blood collected intraoperatively and postoperatively to obtain washed red blood cells for reinfusion.
Device Story
CATSmart is an intraoperative/postoperative autotransfusion system; processes anticoagulated shed blood collected in a sterile reservoir. Operates via continuous flow centrifuge; removes plasmatic components, non-erythrocytic cells, activated coagulation factors, fibrinolysis products, cell trauma, and anticoagulants. Produces washed packed red cells for reinfusion. Used in clinical settings; operated by healthcare professionals. Features include hematocrit monitoring via integrated cuvette in AT3 disposable tubing; touchscreen interface. Output provides hematocrit values for process monitoring; not for diagnostic/quality control. Benefits include recovery of autologous blood for patient reinfusion.
Clinical Evidence
Bench testing only. In vitro blood quality studies compared CATSmart to the predicate C.A.T.S. across three wash programs (emergency, low volume, smart). Results confirmed successful validation of all wash programs using the AT3 tubing set. Separate evaluation demonstrated effective removal of fat and heparin. Electrical safety tested per IEC 60601-1-2:2007; additional testing performed for vibration, shock, and durability.
Technological Characteristics
Continuous flow centrifuge system. Includes AT3 disposable tubing set with integrated cuvette for hematocrit sensing. Touchscreen control interface. Electrical safety per IEC 60601-1-2:2007. System supports multiple wash programs (emergency, low volume, smart).
Indications for Use
Indicated for processing autologous shed blood collected intraoperatively and postoperatively to obtain washed packed red blood cells for reinfusion in patients undergoing surgery or trauma.

#### 4. Description
The product described in this document is the CATSmart (Continuous Autotransfusion System) including the disposables AT1, AT3, ATS, ATY, ATO, ATR40 and ATR120, ATV-70 and ATV-180, ATF40 and ATF120.
The Fresenius Kabi CATSmart device is an intraoperative autotransfusion system for intraand/or postoperative processing of blood lost through surgery or trauma. The CATSmart device operates on the principle of a continuous flow centrifyge, comparable to continuous systems for hemapheresis which, for decades, have been widely used in blood banks.
The shed blood, which is anticoagulated and collected in a sterile reservoir, is processed in a continuous washing process to obtain washed packed red cells for reinfusion to the patient. During this process all plasmatic and non-erythrocytic cellular components of the collected blood, and thus activated coagulation factors, products of fibrinolysis and cell trauma as well as the anticoagulant are removed. The packed red cells are collected in a reinfusion bag from which they can be reinfused to the patient via a transfusion set when needed.

CATSmart is based on the predecessor products C.A.T.S. and C.A.T.SP."", which have been in clinical use for almost 20 years. CATS was originally cleared in 1996. Following minor modifications it has been marketed as C.A.T.Smits since 2005. CATSmart has as an additional technical feature: monitoring of the hematocrit value.
# 5. Intended Use
The CATSmart (Continuous Autotransfusion System) device by Fresenius Kabi is an autotransfusion device indicated for the processing of autologous shed blood collected intraoperatively and postoperatively to obtain washed red blood cells for reinfusion.
# 6. Substantial Equivalence
Fresenius CATSmart is substantially equivalent to the predicate device system, with the following components.
#### a) The reusable autotransfusion device:
CATSmart is based on the predecessor products C.A.T.S. and C.A.T.SP.446, which have been in clinical use for almost 20 years. The main functions of CATSmart and the underlying methodology remained unchanged. In fact, the only functional difference of CATSmart compared to C.A.T.S./C.A.T.S./C.A.T.S./C.A.T.S. of the hematocrit value as an additional technical feature. Moreover, the main controller software was updated. The update includes the hematocrit function as a new item and usage of a touchscreen control instead of a keyboard. The software structure and the requirements remain unchanged compared to the C.A.T.S./C.A.T.Splus software.
#### b) Disposables:
The predicate device C.A.T.S./C.A.T.SPl46 system also includes the disposable blood processing chamber with all necessary tubing (called AT1) as described in the 510(k) submission K960006. The new disposable for the proposed device CATSmart is AT3. The only difference between AT3 and AT1 is the integration of a cuvette into the tubing for the hematocrit measurement. The AT1 disposable may also be used with CATSmart, but no hematocrit information will be displayed.
The following disposables have received prior 510(k) clearance, do not change in their usage with CATSmart, and are not further mentioned in this 510(k):
- ATS suction line (cleared under K984233), -
- ATY Y-Adapter (cleared under K984233). -
- -ATO Oxygenator Line (cleared under K984233).
- ATR40 Autotransfusion Reservoir (cleared under K984586), -
- ATR120 Autotransfusion Reservoir (cleared under K984586) -

Image /page/6/Picture/1 description: The image contains the logo for Fresenius Kabi. The logo consists of three blue, curved lines on the left side. To the right of the lines, the text "FRESENIUS KABI" is written in blue, with "FRESENIUS" on top of "KABI".
The following additional disposables are exempted from 510(k) submission, do not change with their usage with CATSmart, and are not further mentioned in this 510(k):
- -ATV-70 and ATV-180 vacuum lines. These devices are classified as cardiopulmonary bypass accessory equipment and exempted according to 21 CFR & 870.4200.
#### Discussion of differences between CATSmart and the predicate device.
The only functional difference of CATSmart compared to C.A.T.S./C.A.T.Sn/W is the monitoring of the hematocrit value as an additional feature. The hematocrit monitoring function of CATSmart is only used to monitor the wash process for informational purposes and is not intended for diagnostic or quality control purpose. As stated in the Operator's Manual, the hematocrit values given by the device are not a substitute for the hematocrit check on the product before it is reinfused in the patient. The sensors are not calibrated measuring instruments.
#### Conclusion:
Based on the identified characteristics it is claimed that the device is substantially equivalent to the predicate devices.
### 7. Performance testing
The performance of the CATSmart device was tested by in vitro blood quality studies in direct comparison to the predicate device C.A.T.S. (currently marketed as C.A.T.Sº™). All three wash programs (emergency wash program, low volume wash, smart wash) were tested. Overall it was judged that all validation tests were passed for all wash programs on the CATSmart device with the AT3 tubing set. A separate in vitro evaluation demonstrated that fat and heparin were almost completely removed from the processed blood. The electrical safety of the CATSmart device was tested according to the general requirements for basic safety and essential performance directive of IEC 60601-1-2:2007. Furthermore, vibration and shock resistance was tested as well as the durability.
