Upon initial device testing subsequent to implantation… Distribution data in the federal record shows the product reached: Worldwide - Nationwide distribution in the state of Illinois and countries of Russia and United Kingdom. Distribution scope directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
To put this record in context, PlainRecalls indexes 83,949 recalls across the FDA, CPSC, NHTSA and USDA FSIS going back to 1995. Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by FDA Devices. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines. This recall is roughly 7 years old; older recalls can remain relevant because many units enter resale, rental, and secondary-market channels where the original warning never reaches the end user. Always cross-check the recall number against the official agency page before relying on any summary.

Product Description
AD-TECH Spencer Probe Depth Electrode Product Usage: The Ad-Tech Depth Electrodes (Depth Electrodes, Foramen Ovale Depth Electrodes, Macro Micro Depth Electrodes, Spencer Probe Depth Electrodes, Wyler Sphenoidal Depth Electrodes) are intended for temporary (< 30 days) use with recording, monitoring and stimulation equipment for the recording, monitoring and stimulation of electrical signals at the subsurface level of the brain. The recording of electrical activity supports definition of the location of epileptogenic foci and brain mapping.
Reason for Recall
An Ad-Tech Clinical Specialist, attended a case on April 15, 2019. During the case the surgeon encountered an issue after implanting four Ad-Tech depth electrodes. Upon initial device testing subsequent to implantation it was identified that two of the devices that were labeled as 8 contact depth electrodes (SD08R-SP05X-000) were in fact 6 contact depth electrodes (SD06R-SP05X-000) . There was no impact to the patient due to this incident.
