FDA Recall Database: Class I Recall: WATCHMAN TruSeal Access System DBL, OUS, Material Number… by Boston Scientific Corporation

Key facts

What this classification means

A Class I recall is FDA’s most serious classification. FDA assigns Class I when there is a reasonable probability that use of, or exposure to, the recalled product will cause serious adverse health consequences or death. This classification does not mean harm has already occurred in every case -- it reflects FDA’s assessment of the realistic worst-case risk profile of the defect described in the recall, based on the reason for recall reported by the firm. Class I recalls receive the closest FDA monitoring of the three classes: the recalling firm typically must submit a recall strategy, periodic status reports, and effectiveness checks confirming that the affected lots have actually been removed from distribution or corrected in the field. FDA's Center for Devices and Radiological Health (for devices) or Center for Drug Evaluation and Research (for drugs) reviews the classification and can require additional corrective action if the initial response is judged insufficient. Because this record is filed as Class I, professionals and consumers handling an affected lot should treat FDA's own classification -- not this page's summary of it -- as the authoritative risk signal.
