Designed to Improve Outcomes With Real-Time Intelligence
Designed for Heart Surgeons
A minimally invasive heart pump that delivers full support,
allowing the heart to rest; enabling full recovery.
Impella 5.5® with SmartAssist®
Minimally invasive heart pump providing full support with maximum unloading.
Minimally Invasive
- Eliminating the need for a sternotomy or coring of the left ventricle
The Surgeon’s Heart Pump
- Insert via axillary artery or anterior aorta using familiar surgical skills
Full Support with Maximum Unloading
- Reduces the heart’s oxygen demand and workload
- Forward flow provides coronary and end organ perfusion
Equipped with SmartAssist
- Designed to optimize survival and native heart recovery
SmartAssist Advanced Metrics
Advanced Metrics
Designed to optimize pump management and assist in weaning
- Left ventricular placement signal
- Less invasive heart pump with the ability to display cardiac power output
- Designed to optimize survival and native heart recovery
- Clear, concise alarms for improved troubleshooting
Cardiac power output (CPO) is the #1 correlate to mortality
in AMI cardiogenic shock.1
CPO (in watts)= (MAP x Cardiac Output) / 451
Metrics are for informational purposes only. Any change in the trend should
be verified independently using a cleared or approved diagnostic device.

and left ventricle - Real-time in-vivo pump flow
Metrics During Intervention

1
At the initiation of the balloon inflation, the aortic placement signal begins to dampen and eventually diminishes, demonstrating unloading with Impella support.
2
The longer the balloon is inflated,
notice the uncoupling of AO and LV waveforms due to the decreased contractility of the heart.
3
When balloon is deflated, the return
of pulsatility is demonstrated.
Post-intervention, trend screen
may be used to assess weaning.

Weaning Interface for Native Heart Assessment
Observing trends in pump metrics during weaning
- Observe trends in LVEDP and MAP
- Look for stable LVEDP and MAP
- Assess native heart recovery as pump flow decreases
Metrics are for informational purposes only. Any change in the trend should be verified independently using a cleared or approved diagnostic device.
Improved Troubleshooting for Suction Management
The LV placement signal can provide additional information to assist in troubleshooting.
Suction
- Reduce P-Level
- Check filling and volume status
- Check Impella position
