Explantation and Device Replacement
Explantation
• Interrogate the device status.
• Deactivate VT and VF therapies prior to explantation.
• Remove the leads from the header. Do not simply cut them loose.
• Use state-of-the-art techniques to remove the device and, if necessary, the leads.
Note: Normal oxidation processes may cause ICD housing discolorations. This is
neither a device defect nor does it influence device functionality.
• Explants are biologically contaminated and must be disposed of safely due to risk of
infection.
Device replacement
If, upon replacing the device, already implanted leads are no longer used but left in the
patient, then an additional uncontrolled current path to the heart can result.
• Deactivate VT and VF therapies prior to device replacement.
• Insulate connections that are not used.
Basic principles:
• The device must not be resterilized and reused.
Cremation
Devices must not be cremated.
• Explant the device before the cremation of a deceased patient.
Disposal
BIOTRONIK takes back used products for the purpose of environmentally safe disposal.
• Clean the explant with an at least 1% sodium hypochlorite solution.
• Rinse off with water.
