Proclaim XR and Proclaim Plus Implantable Pulse Generator Recall Follows Dozens of Reports Involving MRI Injuries

Injuries have been linked to the implantable devices failing to deliver therapy after they lost connection to patients' mobile devices after an MRI

Abbott has issued a recall of more than 155,000 implantable pulse generator devices, which are used to provide brain and spinal cord stimulation to individuals with Parkinson’s disease and other movement disorders, following dozens of reported injuries that occurred when the implants were unable to be reactivated following an MRI procedure.

The U.S. Food and Drug Administration (FDA) announced the implantable pulse generator recall on September 13, indicating the manufacturer is aware of at least 186 incidents involving failure of therapy delivery, which has resulted in at least 73 injuries.

The implantable systems provide work by delivering low electrical impulses to nerve structures. The devices can be placed in MRI (magnetic resonance imaging) mode, which disables therapy delivery while patients are undergoing an exam. The MRI mode is supposed to be deactivated wirelessly using an iPhone or iPod application after the MRI scan is complete, so to resume therapy.

However, according to the recall notice, the manufacturer has received complaints indicating the connected iPhone or iPod lost communication with the implanted device, which can prevent it from exiting MRI mode and resuming therapy delivery. This appears to occur after a connected iPhone or iPod received an update, after the application was updated or deleted, and after the device was removed from the list of paired devices.

Federal regulators warn that patients with implantable devices that fail to deliver therapy may require surgery to remove and replace the device.
