After further clinical review of this event with bard's medical department, this event was reassessed and determined to be mdr reportable as a malfunction pursuant to 21 cfr part 803.A manufacturing review was conducted and the reported lot met all release criteria.The complaint investigation is inconclusive as the sample was not returned for evaluation.It should be noted that per the event description, the marker was deployed within a compressed breast.Therefore, it is possible that procedural issues contributed to the reported event.Based on the available information, the definitive root cause is unknown.The information provided by bard represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant/reporter was unable or unwilling to provide any further patient, product, or procedural details to bard.
