Manufacturing review: the device history records were reviewed with special attention to the raw materials, subassemblies, manufacturing process and quality control testing.This lot met all release criteria.There was nothing found to indicate there was a manufacturing related cause for this event.This is the only event reported to date for this lot number and failure mode.Visual inspection: the sample was returned.The distal tip was missing and not returned with the device.The outer catheter remained intact.At the distal end of the device, the marker band was present.The core wire was broken approximately 144.6cm from the distal tip.Therefore, approximately 1.4cm of the core wire and distal tip were not returned for evaluation.The distal end of the outer catheter and inner catheter was jagged.Functional/performance evaluation: functional testing could not be performed due to poor sample condition (i.E.Tip detachment).Medical records review: medical records were not provided for review.Image/photo review: images/photos were not provided for review.Conclusion: the investigation is confirmed for a tip detachment, as the metal tip was missing from the distal end of the catheter.The investigation is inconclusive for device inoperable, as no functional testing could be performed due to poor sample condition (i.E.Tip detachment).The root cause could not be determined based upon available information.It is unknown if procedural issues contributed to the event.Labeling review: the current ifu (instructions for use) states: warnings and precautions: prior to use, the packaging and product should be inspected for signs of damage.Never use damaged product or product from a damaged package.Additionally, precautions and specific directions for use of the crosser cto recanalization catheter are included in the ifu.(b)(4).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.
