IMPELLA RP
CATHETER
®
The Impella RP
Catheter is an intracardiac microaxial blood pump that delivers up to 4.0 liters of
®
blood per minute from the inferior vena cava into the pulmonary artery. Figure 2 illustrates the
Impella RP
Catheter.

DIFFERENTIAL PRESSURE SENSOR
The Impella RP
Catheter has an electronic differential pressure sensor located at the proximal end
®
of the cannula. The purpose of the pressure sensor is to generate the placement signal used to
calculate the flow generated by the Impella RP
The pressure sensor is a flexible membrane integrated into the cannula. One side of the sensor is
exposed to the blood pressure on the outside of the inlet area and the other side is exposed to the
pressure of the blood inside of the cannula. The sensor generates an electrical signal proportional to
the difference between the pressure outside the inlet area and the pressure inside the cannula. This
signal is displayed on the Automated Impella
Impella RP
®
with the Automated Impella
Catheter.
