Weaning the patient from the Impella® Catheter is at the discretion of the physician. The Impella 2.5 and CP Systems have been approved for ≤ 4 days and the Impella 5.0 and LD Systems have been approved for ≤ 6 days of use.
However, weaning could be delayed beyond the normal use for temporary support as an unintended consequence of continued instability of the patient’s hemodynamics. Inability to wean the patient from the device within a reasonable time frame should result in consideration of a more durable form of left ventricular support.
