Impella® LD

Impella 2.5

The Impella LD pump is a minimally invasive, catheter- based cardiac assist device designed to directly unload the left ventricle, reduce myocardial workload and oxygen consumption while increasing cardiac output, coronary and end- organ perfusion.

The Impella LD can be inserted into the left ventricle via open chest procedures. The Impella LD pump is inserted through the ascending aorta, across the valve and into the left ventricle.

Micro-Axial Blood Pump

  • Delivers forward-flow from the left ventricle to the aorta
  • 9 Fr catheter-based platform
  • 21 Fr micro-axial pump
  • Minimal bedside support

Single Access Point

  • No priming/no blood outside the body
  • Multiple large bore cannulae not required

Direct Ventricular Unloading1, 2, 3, 4, 5, 6

  • Actively unloads up to 5 L/min from left ventricle
  • Reduces wall tension and myocardial O2 demand
  • Increases O2 supply
  • Reduces inotrope dependence
  • Provides ventricular unloading unlike ECMO
