2.5 Catheter Components (cont’d)
Component Description
Motor housing The motor housing is 12 Fr in diameter and consists of a completely
encapsulated motor.
Open pressure area The open pressure area is an opening located between the motor
housing and the distal end of the catheter shaft.
Catheter shaft A 9 Fr catheter shaft is located between the motor housing and
the plug. The lumen of the catheter shaft contains a purge lumen, a pressure measurement lumen, and a pump monitoring cable. The catheter shaft has longitudinal and transversal marks:
• The longitudinal marks along the inner radius of the cannula show
the position of the curved, flexible cannula.
• The transversal marks at 1 cm intervals aid in proper positioning.
Repositioning unit The repositioning unit consists of an introducer and an
anticontamination sleeve with an anchoring ring.
• The introducer (with hemostatic valve) is graduated from 11 Fr to 15 Fr. It is located on the catheter shaft and allows repositioning of the catheter.
• The anchoring ring of the anticontamination sleeve secures the
catheter sheath to the introducer.
Plug The plug at the proximal end of the catheter connects the catheter to
the Impella® Controller through a connector cable. It has two sidearms: a red pressure sidearm and a clear sidearm.
Red pressure sidearm The red pressure sidearm is attached to a standard pressure bag and is
used to prime the line of the pressure measurement system.
Clear sidearm The clear sidearm is attached to the purge cassette purge line. It leads
to the infusion filter, the pressure reservoir, and the check valve.
Infusion filter The infusion filter prevents bacterial contamination and prevents air
from entering the catheter.
Pressure reservoir The pressure reservoir includes a flexible rubber diaphragm that
provides additional filling volume by means of an expansion chamber during purge solution change.
Check valve The yellow check valve ensures that purge fluid does not flow in the
reverse direction when the purge solution is exchanged.

PURGE CASSETTE
Do not use saline in the purge system.
The purge cassette delivers rinsing fluid to the Impella® pump. The purge fluid (typically 20% dextrose solution plus heparin 50 IU/mL) flows from the purge cassette through the catheter to the microaxial blood pump to prevent blood from entering the pump motor. Figure 3.5 illustrates the purge cassette and related components. Table 3.2 describes each component.

4 cm of the stiffer part of the guidewire are visible in the left ventricle.
8. Remove the 6 Fr diagnostic catheter.
9. Wet the cannula with sterile water and backload the pigtail section of the catheter onto
the placement guidewire. One or two people can load the catheter on the guidewire.
One-person technique
a. Advance the guidewire into the Impella® Catheter and stabilize the cannula
between the ngers as shown in Figure 5.9. This prevents pinching of the inlet port. The guidewire must exit the outlet port on the inner radius of the cannula, as shown by the arrow in Figure 5.9 and in Figure 5.10. The catheter can be hyperextended as necessary to ensure the guidewire exits on the inner radius of the cannula.
If the Impella the OR as part of open heart surgery, manipulation may be performed only through the 9 Fr steering catheter. Direct manipulation of the pump assembly through the aorta or ventricle may result in serious damage to the Impella device and serious injury to the patient.
Avoid Damaging Inflow Area

Alternative to Waiting Until ACT < 150
If you do not want to wait until ACT is below 150 seconds before removing the device, you can remove the device and exchange the peel-away sheath with a non peel-away sheath and dilator over the wire. Then you can wait until ACT is below 150 seconds and remove the sheath without risk of bleeding.
USE OF THE REPOSITIONING INTRODUCER AND THE 13 Fr PEEL-AWAY INTRODUCER
To prevent failure of the 13 Fr peel-away introducer, remove the 13 Fr peel-away introducer prior to transport when activated clotting time (ACT) is less than 150 seconds.
1. Flush the sidearm of the repositioning introducer located on the catheter shaft.
2. Carefully flush the sidearm of the 13 Fr introducer and remove the 13 Fr peel-away
introducer completely from the artery over the catheter shaft and apply manual pressure above the puncture site.
3. Grasp the two “wings” and bend back until the valve assembly comes apart. Continue
to peel the two wings until the introducer is completely separated from the catheter shaft (see Figure 5.16).
5.14
Figure 5.16 Removing the 13 Fr Peel-Away Introducer
4. Attach a stopcock and flush the repositioning sheath prior to advancing the sheath.
5. Place two deadend caps on the stopcock to prevent further usage. The sideport should
not be used to give medication or draw blood because the blood could potentially clot. Pressure bags should not be connected to the sideport of the repositioning sheath. If a pressure bag is connected, the sideport must have an infusion pump or flow limiting valve in place to control the amount of fluid administered to the patient.
6. Slide the repositioning introducer over the catheter shaft and advance it into the artery
to the yellow eyelet.
7. Secure the yellow section of the repositioning introducer by suturing it to the skin using
the provided eyelet.
Instructions for Use
8. Slide the proximal end of the anticontamination sleeve onto the yellow section of
the repositioning introducer. Lock the anchoring ring in place by turning it clockwise. Secure the catheter shaft in place by tightening the connected anchoring ring.
9. Carefully extend the anticontamination sleeve to maximum length and secure the end
by tightening the distal anchoring ring.
PURGER PROCEDURES
5 USING THE IMPELLA
®
CONTROLLER WITH THE IMPELLA
When replacing the purge cassette, the replacement process must be completed within 4 minutes. The Impella® 2.5 Catheter may be damaged if replacement takes longer than 4 minutes.
There are four procedures for maintaining the Impella® purge system:
• Purge system change (cassette and purge uid)
• Purge uid change
• Purge cassette change
• De-air purge system
Each procedure can be accessed using the PURGE SYSTEM soft button.
This section describes each of those purger procedures.
PURGE SYSTEM CHANGE
These are the steps you will follow to change out the purge cassette and purge fluid.
1. The purge system change out procedure begins with delivery of a bolus to the pressure
reservoir so that the reservoir can maintain purge pressure during the change out. After the bolus is delivered, the controller automatically proceeds to the next screen.
Replacement Time
If the purge flow is more than 7 mL/hr or the dextrose concentration is less than 20%, replacement time will be less than 4 minutes. Replacement should always be performed as quickly as possible.
®

TROUBLESHOOTING THE PURGE SYSTEM
LOW PURGE PRESSURE
If at any time during the course of support with the Impella®, the Impella® Controller alarms “Impella Failure: Sudden Purge Pressure Drop,” follow the instructions below.
1. Inspect the purge system for leaks.
2. If there are no leaks, change to a purge fluid with a higher dextrose concentration. To
do this, open the PURGE SYSTEM menu and select “Purge Fluid Change”. Follow the instructions on the screen. (Refer to “Purger Procedures” earlier in this section.)
3. If the pressure stabilizes, no other action is required.
If the purge pressure is not stable, proceed to Step 4.
4. If the low purge pressure alarms remain unresolved for more than 5 minutes, this may
be a sign of pump damage. Complete the following steps immediately:
a. Open the flow icon and reduce the flow rate to 0.5 L/min.

PATIENT MANAGEMENT OVERVIEW
The information and instructions in this section of the manual are not intended to supersede established medical procedures concerning patient care. Best practice, as determined by the medical community, should always be observed. In each case, the clinician must determine whether the application of information provided is appropriate for the particular clinical setting.
GENERAL PATIENT CARE CONSIDERATIONS
• Do not raise the head of the bed to higher than a 30-degree angle
• Use knee immobilizer as needed to maintain access site straight
• Perform dressing changes per hospital protocol, using aseptic technique
• Assess access site for bleeding and hematoma
®
• Be careful not to pull on the Impella

Catheter when transferring a patient from one bed
6 PATIENT MANAGEMENT TOPICS
• Monitor pedal pulses
TRANSPORT WITHIN THE HOSPITAL
Patients supported with the Impella® 2.5 System may require transport within the hospital for
®
various reasons. Transport can be safe and simple for patients supported with Impella
Considerations for transport within the hospital:
• The Impella
®
Controller and Impella® 2.5 System are designed to operate on battery
power for at least 1 hour.
• Conrm that the battery capacity displayed on the controller is 100%.
• If transport time might be longer than 1 hour, bring an extension cord or conrm
that you will be able to connect the controller to AC power once you arrive at your destination.
®
• Use care when rolling the Impella
Controller cart, and pay close attention when going
over thresholds and through elevator doors.
®
• Do not stress the Impella
pump cable from the controller to the Impella® red plug.
2.5.
Note: If the Impella
®
Controller is allowed to discharge completely, and the system shuts down due to low battery, the controller will need to charge for an extended period of time before the controller will turn back on.

6.1
RIGHT HEART FAILURE
The Impella® 2.5 is a left-side support device only. Patients being supported by the Impella® 2.5 should be monitored for signs of right heart failure.
Caregivers should monitor the patient closely for the following potential signs of right heart failure:
®
• Reduced output from the Impella
• Suction alarms
• Elevated lling pressures (CVP)
• Signs of liver failure
• Elevated pulmonary pressures
If the patient is exhibiting signs of right heart failure, the clinical team should assess the need for biventricular support.
2.5
CARDIOPULMONARY RESUSCITATION (CPR)
Cardiopulmonary resuscitation (CPR) should be initiated immediately if indicated for any patient
®
being supported by the Impella
If CPR is indicated, the following actions are recommended:
1. Initiate CPR per hospital protocol.
2. Reduce the Impella
3. When cardiac function has been restored:
a. Return the flow rate to previous level.
b. Assess placement signals on the controller.
Note:
• During CPR, placement monitoring and ow calculations will not be accurate.
• If ows do not return to pre-CPR values, verify proper placement of device and sufcient
filling of left ventricle. If placement and filling are not satisfactory, it may be an indication that the device has been damaged.

DEFIBRILLATION
6 PATIENT MANAGEMENT TOPICS
During defibrillation, do
NOT
touch the pump, cables, or Impella® Controller.
Patients supported by the Impella® 2.5 System can be defibrillated. However, caregivers should use caution during defibrillation to ensure they do not touch the pump, cables, or controller.
ECG INTERFERENCE
Operating the Impella® Controller may cause interference with electrocardiogram (ECG) signals. Please check the electrode pads and leads for good fixation and contact. If interference persists, activate the 50/100 Hz band-elimination filter or the 60/120 Hz band-elimination filter (also known as notch filter) on your ECG device. The filter frequency will be based on the AC power frequency for the country in which you are operating the equipment. If your ECG device does
®
not have the appropriate filters, disconnect the Impella to obtain an undisturbed signal. Please observe the battery status while running the Impella Controller off AC power.

POSITIONING AND PLACEMENT DEVICES
High quality fluoroscopic imaging is the best method for determining pump position and is required for pump placement.
Alternative methods for determining pump position include:
• Portable C-Arm uoroscopy
Transesophageal echocardiography (TEE)
• Chest x-ray
Use Fluoroscopy for Placement
®
Impella will be compromised if correct placement cannot be confirmed. While other imaging techniques, such as transesophageal echocardiography (TEE), can help confirm the position of the Impella placement, TEE does not allow visualization of the entire catheter assembly and is inadequate for reliably placing the Impella across the aortic valve.

Notes on Imaging:
All imaging technology represents the anatomy in two dimensions (2D). It is not possible to assess the interactions between the device and the intraventricular anatomy that occur in three dimensions (3D). If a positioning alarm occurs, Abiomed strongly recommends that the device be repositioned, even if the imaging view shows correct position. Abiomed strongly recommends
®
using fluoroscopy to guide placement and positioning of the Impella
Circulatory Support device.
Alternative imaging techniques, such as transesophageal echocardiography (TEE), can be useful to confirm the position of the Impella
®
2.5 after placement. However, TEE is inadequate to reliably perform correct placement across the aortic valve. TEE does not allow visualization of the entire catheter assembly.
SUCTION
Suction may occur if the blood volume available for the Impella® 2.5 pump is inadequate or
®
restricted. Suction limits the amount of support that the Impella and results in a decrease in arterial pressure and cardiac output. It can damage blood cells, leading to hemolysis. It may also be an indicator of right heart failure.
2.5 can provide to the patient
If this alarm occurs, follow the recommended actions in the alarm display by decreasing the flow rate.
1. Check the pump for correct positioning using imaging. Reposition the device by rotating
or moving it into or out of the ventricle slightly. Either or both of these actions could help move the inlet of the device away from the interior ventricular wall.
2. Assess patient’s fluid intake and output to confirm adequate volume status.
3. Confirm right ventricular function by assessing CVP or right side function on echo.
If CVP is not an option, check the pulmonary artery diastolic pressure to assess the patient volume status.
4. Return flow rate to pre-alarm setting.
HEMOLYSIS
When blood is pumped, it is subjected to mechanical forces. Depending on the strength of the blood cells and the amount of force applied, the cells may be damaged, allowing hemoglobin to enter the plasma. Pumping forces can be generated by a variety of medical procedures including heart lung bypass, hemodialysis, or ventricular support device (VAD) support. Patient conditions—including pump position, pre-existing medical conditions, and small left ventricular volumes—may also play a role in patient susceptibility to hemolysis.
6.4
Instructions for Use
Patients who develop high levels of hemolysis may show signs of decreased hemoglobin levels, dark or blood-colored urine, and in some cases, acute renal failure. Plasma-free hemoglobin (PfHgb) is the best indicator to confirm whether a patient is exposed to an unacceptable level of hemolysis. Clinically significant hemolysis is defined as two consecutive PfHgb measurements greater than 40 mg/dL. For surgical patients, the first measurements must be at least 72 hours post-implant.
Management technique may differ depending on the underlying cause of hemolysis. Table 6.1 provides guidance for various circumstances.

UNDERSTANDING AND MANAGING IMPELLA® POSITION ALARMS
The Impella® Controller continuously monitors the catheter based on the placement signal and the motor current.
• Placement Signal:
• Motor Current:
Is the signal characteristic of aortic or ventricular pressure?
Is the signal “pulsatile” or “attened”?
If the system alarms with one of the positioning alarms described below, fluoroscopic imaging is
the best method for conrming position. You can also use TEE or a standard chest X-ray.
If the Impella
®
is either partly (just the pigtail) or completely in the ventricle, reposition the device under imaging guidance. If guidance is not available, use the repositioning guide to reestablish proper placement. (The repositioning guide is discussed later in this section.)
®
If the Impella
is completely out of the ventricle, do not attempt to reposition the device across the valve without a guidewire.
The following pages describe possible placement conditions and the associated signal characteristics and alarm messages as well as actions to take for each.

OPERATING THE IMPELLA® 2.5 WITHOUT HEPARIN IN THE PURGE SOLUTION
The Impella® 2.5 is designed to be operated with a purge solution that contains heparin. Operation of the system without heparin in the purge solution has not been tested. In the event that a patient is intolerant to heparin, due to heparin-induced thrombocytopenia (HIT) or bleeding, physicians should use their clinical judgment in assessing the risks versus benefits of
®
operating the Impella
System without heparin.
If it is in the best interest of the patient to operate the system without heparin, the dextrose solution is still required, and physicians should consider an alternative anticoagulant delivered systemically.
Do not add any alternative anticoagulant (such as a direct thrombin inhibitor) to the purge solution. The Impella
®
2.5 has not been tested with any alternative anticoagulants present
in the purge solution.
GUIDELINES FOR EXPLANT
Patients being supported with the Impella® 2.5 System should be evaluated for explant on a regular basis.
To evaluate patients for explant, reduce the Impella
®
2.5 flow rate and look for the following
signs of native heart recovery:
• AO and CVP pressure remain stable
• Native ejections are visible on the patient pressure monitor
• Native ejections increase after volume loading challenge
• Echocardiography reveals pronounced aortic valve opening
If physicians see these signs of native heart recovery and the patient has demonstrated stable, ongoing recovery—including stable organ (eg, liver, kidney, lung) function—the patient should be considered for explant.
®
If the patient does not meet the criteria for explant, the patient should remain on Impella
2.5
support, or be transitioned to a longer term device.
