When someone dies with a medical implant inside their body, that device does not simply cease to exist. The battery still holds a charge. The casing is still intact. The materials are still subject to handling and disposal regulations. For families already managing the weight of loss, discovering that a pacemaker, defibrillator, or neurostimulator requires specific action before arrangements can proceed is often an unexpected complication. Understanding what happens — and who handles it — removes one layer of uncertainty from an already difficult process.
The Devices Most Commonly Involved
Cardiac devices account for the majority of cases. Pacemakers regulate heart rhythm through a battery-powered generator implanted just below the collarbone, and implantable cardioverter-defibrillators work similarly but with the added capacity to deliver an electric shock during a life-threatening arrhythmia. Both contain lithium-ion batteries that remain active after death.
Beyond cardiac devices, the list extends further than most families realise. Spinal cord stimulators, deep brain stimulators used in Parkinson’s disease management, implanted insulin pumps, cochlear implants, and vagus nerve stimulators are all battery-powered devices that may be present in a deceased person and should be considered before cremation proceeds.
Why Cremation Changes Everything
For burial, most implants can remain in place without incident. For cremation, the situation is entirely different. Cremation chambers reach temperatures that cause lithium-ion batteries to react violently, producing an explosion capable of damaging the cremation equipment, injuring staff, and forcing a costly shutdown of the facility. This is not a remote risk. Documented incidents have occurred in crematoria internationally, and the removal of all battery-powered implants before cremation is a standard safety and regulatory requirement at reputable facilities.
The American Heart Association has reported on the scale of the issue, noting that tens of thousands of devices are removed from deceased patients annually in the United States alone, with researchers estimating the combined value of discarded viable devices approaches hundreds of millions of dollars each year.
Who Removes the Device and How
Families are not expected to arrange removal themselves. For standard pacemakers and ICDs, a trained mortician or funeral professional handles the procedure as part of routine preparation. The generator sits close to the skin surface, and removal is straightforward. Deeper devices, such as spinal cord stimulators or leadless pacemakers, implanted directly inside the heart, may require the involvement of a pathologist or clinical specialist, depending on the device and local protocols.
Experienced funeral directors Brisbane and across Queensland will ask about implanted devices at the point of first contact with the family. Disclosure at this stage allows the right preparation to be arranged before the body is transferred, avoiding delays later in the process.
What Families Should Do
The most useful action is simple: disclose any known implants at the first conversation with the funeral provider. If the deceased carried an implant identification card, typically issued at the time of the procedure and often kept in a wallet, this provides the make, model, and placement details the provider needs. If no card is available, a general description is enough to prompt the right checks. For anyone managing end-of-life planning in advance, noting the presence of any implanted device in written instructions, alongside a will or funeral directive, ensures the information reaches the right people without relying on memory under pressure.
