A further clinical review of this event was performed and identified the event to be mdr reportable pursuant to 21 cfr part 803.A manufacturing review was conducted.The lot met all release criteria.The device was returned for evaluation.The outer catheter appeared to be bunching and partially separated from the distal tip.The device was able to produce vibrations throughout the entire length of the catheter.Misting was observed coming out from the distal tip, indicating that the device was vibrating properly.The distal tip of the catheter was pressed against one end of a 5mm plaster title, and was able to penetrate the tile with no issues.Upon removal from the plaster tile, the outer catheter separated from the distal tip.The investigation is confirmed for material separation based upon the condition in which the sample was returned.The investigation is unconfirmed for device inoperable, as the device was able to successfully vibrate and mist during functional testing.The root cause could not be determined based upon available information.As another catheter was used without issue with the same generator, it is unknown if procedural issues contributed to the event.Section a through d- 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.
