PURGE CASSETTE
Do NOT use saline in the purge system.
The purge cassette delivers rinsing fluid to the Impella® RP Catheter. The purge fluid (typically
20% dextrose solution) flows from the purge cassette through the catheter to the microaxial
blood pump to prevent blood from entering the motor. When the purge cassette is properly
installed in the Automated Impella® Controller, the words on it are upright and facing you.
The image of the purge fluid appears on the left with arrows pointing toward the image of the
person on the right. Figure 3.5 illustrates the purge cassette and related components. Table 3.2
describes each component.
