Designed for Cardiac Surgeons
The Impella 5.5® with SmartAssist® Heart Pump is designed for surgeons who want to offer their patients complete left ventricular unloading with full systemic flow. Here you can find all information about the Impella 5.5 with SmartAssist heart pump. It is applied via the axillary artery or directly via the aorta using common surgical methods. In doing so, it results in direct unloading of the left ventricle by reducing ventricular work for a period of up to 30 days. The Impella 5.5 with SmartAssist heart pump is used, for example, in patients with cardiogenic shock.
Optimized Patient Management Through Further Developed Pump Key Figures
How can Impella 5.5 with SmartAssist support you in your daily clinical routine? The Impella 5.5 with SmartAssist's enhanced pump metrics make it easier to use the heart pump and, together with Impella Connect cloud-based remote monitoring, provide improved patient outcomes. Metrics facilitate patient management. For example, they assist in pump positioning and, thanks to special weaning algorithms, in the weaning phase, thus helping to optimize native cardiac recovery and outcome.
Improved Clinical Outcomes Using Impella 5.5 with SmartAssist Compared to Impella 5.0® in Patients with Cardiogenic Shock And Heart Failure
Clinical Evidence for Impella 5.5 With SmartAssist
A study published in the journal ASAIO examined outcomes of the first 55 patients treated with Impella 5.5 with SmartAssist at Cleveland Clinic, Hackensack University Medical Center/Hackensack Meridian Health and Cedars-Sinai Medical Center. Study authors and cardiac surgeons Ed Soltesz, MD, Mark Anderson, MD, and Danny Ramzy, MD, conclude that Impella 5.5 with SmartAssist is clinically appropriate for a number of challenging scenarios, including cardiogenic shock after AMI.2

Prof. Reichenspurner from Hamburg presented the study design of the first pilot study of the IMpella-protected cArdiaC surgery Trial (IMPACT).
Extended Support With pMCS Makes Bridge-to-Scenarios More Flexible
Dr. Bernhardt, Hamburg, Germany, demonstrated the utility of Impella® 5.0 and 5.5 cardiac pumps for bridge-to-decision (BTD) in patients with unclear neurological prognosis.
Overview Impella 5.5® With SmartAssist® Heart Pump
The Impella 5.5 with SmartAssist heart pump is indicated for use in cardiogenic shock and is designed to unload the left ventricle and support systemic circulation.
- Hemodynamic support up to 5.5
- Placement via axillary or direct aortic access
- Small motor diameter (18 Fr) & short motor facilitate placement
- Fiber optic pressure sensor:
- The placement signal is based on physiological pressure
- The optical pressure sensor system provides high-tech pressure measurements for position control (for ventricular pumps)
Shorter catheter (70 cm) for better mobility
Overview of Functions and Indications
- Cardiogenic shock in AMI
- Escalation with mechanical circulatory support
- Acute decompensated heart failure
- Postpartum cardiomyopathy
Intelligent Positioning, Handling and Weaning Thanks to New Sensors
- Integrated optical sensor in the aorta for better position detection
- Allows position correction in the ICU without the need for imaging (only for pumps in the left ventricle)

Indications for Use EU
The Impella 5.5 heart pump is an intracardiac pump for supporting the left ventricle. It is intended for clinical use in cardiology and in cardiac surgery for up to 30 days for the following
indications, as well as others:
• The Impella 5.5 is a cardiovascular support system for patients with reduced left ventricular function, e.g., post-cardiotomy, low output syndrome, cardiogenic shock after acute myocardial infarction.
• The Impella 5.5 may also be used as a cardiovascular support system during coronary bypass surgery on the beating heart, particularly in patients with limited preoperative ejection fraction with a high risk of
postoperative low output syndrome.
Impella 5.5 with SmartAssist Heart Pump is contraindicated in the following situations:
• Mechanical aortic valves, severe aortic valvular stenosis or valvular regurgitation
• Hematological disorder causing fragility of the blood cells or hemolysis
• Hypertrophic obstructive cardiomyopathy (HOCM)
• Aneurysm or necrotomy or severe anomaly of the ascending aorta and / or the aortic arch
• Mural thrombus in the left ventricle
• Ventrikelseptumdefekt (VSD) nach Myokardinfarkt
• Anatomic conditions precluding insertion of the pump
• Other illnesses or therapy requirements precluding use of the pump
• Severe peripheral arterial occlusion disease (PAOD) is a relative contraindication
There are risks of complications with every procedure using a blood pump. These include among others:
· Immune reaction
· Embolism, thrombosis
· Vascular injury through to angionecrotomy
· Positioning problems
· Infection and septicemia
· Dislocation of the pump
· Cardiovalvular injuries due to extreme movement of the suction cannula in relation to the cardiac valve or
as a result of attachment by suction of the pump to the valve system following incorrect positioning
· Endocardiac injuries as a result of attachment of the pump due to suction
· Pump failure, loss of pump components following a defect
· Patient dependency on the pump after use for support
In addition to the risks above, there are other WARNINGS and PRECAUTIONS associated with Impella devices.
