STEPS TO EXCHANGE THE CONTROLLER
Step 1:
Have the patient sit or lie down.
Step 2:
Place the new controller within easy reach.
Step 3:
Connect back-up power sources (batteries or AC
Power) to the new controller.
l
Confirm that the power cables are properly
locked on the controller by gently pulling on the
cable near the connector.
l
A “Power Disconnect” alarm will activate if a
second power source is not connected to the
new controller within 20 seconds of controller
power up
l
A “VAD Stopped” alarm will activate if the pump
driveline is not connected to the new controller
within 10 seconds - this alarm will resolve once
the pump driveline is connected
Step 4:
Pull back the white driveline cover from the
original controller’s silver connector.
Step 5:
Disconnect the driveline from the original
controller by pulling the silver connector away
from the controller. Do not disconnect by pulling
on the driveline cable. A “VAD Stopped”
alarm may activate. Don’t panic. You can silence
the alarm after restarting the pump, which is the
priority.
Step 6:
Connect the driveline to the new controller (align
the two red marks and push together). If the “VAD
Stopped” alarm was active on the new controller, it
will now resolve.
Step 7:
The pump should restart. Verify the pump is
working (RPM, L/min, Watts).
Step 8: IF THE PUMP DOES NOT RESTART, CALL FOR
MEDICAL ASSISTANCE IMMEDIATELY.
Step 9:
Insert the Alarm Adapter into the blue connector
on the original controller.
l
Disconnect both power sources from the
original controller.
l
The controller will be turned off and all alarms
silenced.
Step 10:
Slide the white driveline cover up to cover new
controller’s silver connector.
Step 11:
Contact the VAD Center or Implanting hospital
for a new backup controller.
