Impella® Heart Pumps for More Safety

Impella catheters offer hemodynamic support and more safety during cardiogenic shock or percutaneous coronary interventions (Protected PCI). Depending on the indication, different product variants are available.

The Impella Product Family

Haemodynamic Support with Impella Heart Pumps

During a high-risk PCI or in cardiogenic shock, Impella systems can unload the heart. The Impella heart pump increases ejection fraction while simultaneously reducing the heart’s work. This unloads the left ventricle and improves the cardiac output as well as coronary blood flow.

Product Variations

Impella 2.5® heart pump

How it works: The Impella 2.5® heart pump pulls blood from the left ventricle through an inlet area near the tip and delivers blood from the cannula into the ascending aorta.

Indications: Reduced left ventricular function, cardiogenic shock, Protected PCI

Insertion: The pump can be inserted via a standard catheterization procedure through the femoral artery, into the ascending aorta, across the valve and into the left ventricle. There, the pump actively and continuously expels blood from the left ventricle via the aortic valve to the ascending aorta.

Effects:

  • Stabilizes hemodynamics
  • Unloads the left ventricle
  • Provides end organs with blood
  • Allows the heart to recover

Performance: The Impella 2.5 heart pump allows a maximum flow of 2.5 liters per minute.

Impella CP® heart pump

How it works: The Impella CP® heart pump pulls blood from the left ventricle through an inlet area near the tip and delivers blood from the cannula into the ascending aorta.

Indications: Reduced left ventricular function, cardiogenic shock, Protected PCI

Insertion: The Impella CP system can be inserted via a standard catheterization procedure through the femoral artery, into the ascending aorta, across the valve and into the left ventricle. There, the pump actively and continuously expels blood from the left ventricle via the aortic valve to the ascending aorta.

Performance: The Impella CP heart pump allows a maximum flow of 3.5 liters per minute.

Impella 5.0® heart pump

How it works: The Impella 5.0® catheter is an intravascular microaxial blood pump that delivers up to 5.0 L/min of forward flow from the left ventricle to the aorta.

Indications: Cardiogenic shock

Insertion: The Impella 5.0 system can be inserted into the left ventricle via the femoral artery or through the axillary artery, and goes through the ascending aorta, across the valve and into the left ventricle.

Impella RP® heart pump

How it works: The Impella RP® heart pump delivers blood from the inlet area, which sits in the inferior vena cava, through the cannula to the outlet opening near the tip of the catheter in the pulmonary artery. 

Indication:

  • Failure of the right ventricle
  • Decompensation after the implantation of a left ventricular heart support system 
  • Heart attack
  • Heart transplant
  • Open heart surgery
  • Biventricular heart support

Insertion: The Impella RP heart pump can be inserted through a standard catheterization procedure through the femoral vein and into the right atrium, across the tricuspid and pulmonic valves, and into the pulmonary artery, to support a patient’s pulmonary circulation and provide hemodynamic stability..

Automated Impella® Controller

How it works: The Automated Impella® Controller is the primary user control interface for the Impella platform featuring a 10-inch high-resolution display. It controls the Impella catheter performance, monitors for alarms, and displays real-time hemodynamic and catheter position information.

The integrated purge system automatically sets the purge flow to maintain the purge pressure and eliminates the need to actively monitor purge pressures. Step-by-step on-screen procedures allow for quick and simple set-up and purge cassette procedures; featuring automatic priming, detection of connections, and automatic bolus at completion.

The Automated Impella Controller can be powered by AC power or can operate on internal battery power for at least 60 minutes when fully charged.

Warnings and contraindications

The left-side Impella heart pump is contraindicated for use with patients experiencing any of the following conditions: (1) Mechanical aortic valves, severe aortic valvular stenosis or valvular regurgitation; (2) Hematological disorder causing fragility of the blood cells or hemolysis; (3) Hypertrophic obstructive cardiomyopathy (HOCM); (4) Aneurysm or necrotomy or severe anomaly of the ascending aorta and / or the aortic arch; (5) Mural thrombus in the left ventricle; (6) Ventricular septal defect (VSD) after myocardial infarction; (7) Anatomic conditions precluding insertion of the pump; (8) Other illnesses or therapy requirements precluding use of the pump; (9) Severe peripheral arterial occlusion disease (PAOD) is a relative contraindication.

The Impella RP catheter is contraindicated for use with patients experiencing any of the following conditions: Arteriosclerosis, in particular calcification or other disorders of the pulmonary artery wall; mechanical valves, severe valvular stenosis or valvular regurgitation of the tricuspid valve or pulmonary valve; mural thrombus of the right atrium or vena cava; anatomic conditions precluding insertion of the pump; other illnesses or therapy requirements precluding use of the pump; presence of a vena caval filter or caval interruption device, unless there is clear access from the femoral vein to the right atrium that is large enough to accommodate a 22 Fr catheter.

Additionally, potential for the following risks has been found to exist with use of the Impella system: Bleeding; Hemolysis; Immune reaction; Embolism, thrombosis; Vascular injury through to angionecrotomy; Infection and septicemia; Endocardiac injuries due to attachment by suction of the pump to the inferior vena cava; Pump failure, loss of pump components following a defect; Patient dependency on the pump after use for support.
