For low risk patients, the Impella Catheter can be removed at bedside after weaning.

Bedside explant process 

1. Stop systemic heparin infusion
2. Change purge solution to non-heparinized fluid (e.g D5%W)
3. Wait until ACT drops below 150 seconds.
4. Set P-Level to P-2.
5. Pull the Impella® CP cathter slowly back to get the cathter inside the aorta. You will feel a resistance when you reach approximately 30-35 cm.
6. Set the P-Level to 0 or discconnet the cathter from the Automated Impella® Controller.
7. Remove the Impella® Catheter and repositioning sheath together (the catheter will not come out through the repositioning sheath).
8. Apply manual compression for 40 minutes or per hospital protocol.

When pulling the Impella® Catheter, you should not have any resistance. If there is any resistance before reaching 30-35cm, stop and notify the interventional cardiologist immediately. Check the catheter position with Echocardiography and X-Ray.
