Recall Insight
This FDA Devices action (record #Z-0637-2021) was formally reported on December 23, 2020, with the manufacturer initiating the action on November 3, 2020. It is classified under Moderate severity (Class II), with a current status of Ongoing. Boston Scientific Corporation is listed as the recalling firm, operating out of Marlborough, MA. Federal records indicate 90 (OUS) units are affected.
The documented reason for this recall is: This is a follow-up to the EKOS Field Safety Notice dated April 30, 2019. The Radio Frequency (RF) board has been redesigned to prevent occasional internal board failures at lower temperatures. All EKOS CU 4.0 consoles … Distribution data in the federal record shows the product reached: No US distribution. Foreign distribution to Latin America and EU.. 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 6 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.
