Intended Use

The CATSmart System by Fresenius Kabi is an autotransfusion device indicated for the processing of autologous shed blood collected intraoperatively and postoperatively to obtain washed packed red blood cells for reinfusion. Additionally, it can be used for perioperative separation of blood into Packed Red Cells (PRC), Plasma (PLS) and Platelet Rich Plasma (PRP).

Device Story

CATSmart is an automated continuous flow centrifuge system for intraoperative and postoperative autotransfusion. It processes anticoagulated shed blood collected in a sterile reservoir; performs continuous washing to remove plasma, non-erythrocytic components, activated coagulation factors, fibrinolysis products, and anticoagulants; and collects washed packed red cells in a reinfusion bag. The system also performs Plasma Sequestration (PSQ) to separate blood into Packed Red Cells, Plasma, and Platelet Rich Plasma based on density and particle size in a centrifugal field. Operated by clinical staff in surgical or trauma settings, the device provides processed blood components for patient reinfusion. It utilizes specific disposable tubing sets and includes an integrated hematocrit monitoring feature. The system aims to reduce the need for allogeneic blood transfusion by recovering and processing a patient's own shed blood.

Clinical Evidence

Bench testing only. In vitro blood quality studies compared the CATSmart device to the predicate C.A.T.S. system. Validation focused on the PSQ procedure using the PSQ set and AT3 tubing set. Results demonstrated that the new PSQ wash program passed validation tests.

Technological Characteristics

Continuous flow centrifuge; utilizes disposable tubing sets (AT1, AT3, ATS, ATY, ATO, ATR40, ATR120, ATV-70, ATV-180, ATF40, ATF120, ATV-F140, PSQ set). Features integrated hematocrit monitoring. Operates via physical separation of cellular components in a centrifugal field based on density and particle size. Software-controlled wash programs.

Indications for Use

Indicated for patients undergoing surgery or trauma requiring autologous blood processing to obtain washed packed red blood cells for reinfusion, or perioperative blood separation into Packed Red Cells, Plasma, and Platelet Rich Plasma.

The CATSmart device operates on the principle of a continuous flow centrifuge, comparable to continuous systems for hemapheresis which for decades, have been widely used in blood banks.

In a typical CATSmart procedure, 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.

In the Plasma Sequestration (PSQ) procedure, the patient's blood is separated into packed red cells (PRCs), plasma (PLS) and platelet rich plasma (PRP). The principle of separation during plasma sequestration is the same as it is for autotransfusion i.e. physical separation of cellular components in the centrifugal field based on the differences in density and particle size. There is no change to system hardware or disposable sets described previously in K160735.

The system includes the disposables AT1. AT3. ATS. ATY. ATO. ATR40 and ATR120. ATV-70 and ATV-180, ATF40 and ATF120. An ATV-F140 disposable set has been created (Class I 510(k) exempt). Also, PSQ disposable cleared under K971274 has also been qualified for use with the CATSmart System for the PSQ procedure.

An additional wash program has been developed and added to the software to manage the PSO procedure.

# V. Indications for Use

The CATSmart System 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.

Additionally, it can be used for perioperative separation of blood into Packed Red Cells (PRC), Plasma (PLS) and Platelet Rich Plasma (PRP).

The indications for use of the CATSmart System, subject of this 510(k), is the same as the predicate device C.A.T.S Autotransfusion System cleared under K971274.

# VI. Comparison of Technological Characteristics with the Predicate Device

The technological characteristics of the CATSmart device used for PSQ procedure remains the same as the predicate C.A.T.S device. The only functional difference of CATSmart compared to C.A.T.S./C.A.T.S?140 is the monitoring of the hematocrit value as an additional technical feature. This feature was evaluated and cleared under K160735.

# VII. Performance Data

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.S.MM). The focus of the validation study was the PSQ procedure using CATSmart. Overall it was judged that the validation tests passed for the new PSO wash program on the CATSmart device with the PSO set and AT3 tubing set.

{5}------------------------------------------------

#### VIII. Conclusions

The performance testing demonstrates that CATSmart is substantially equivalent to the predicate device C.A.T.S Autotransfusion System.
