Manufacturing review: a manufacturing review was conducted.The lot met all release criteria.Visual inspection: the sample was returned.A complete core wire fracture was present 0.9cm from the distal tip.The outer catheter was torn at this location and extended proximally for 5.6cm.The proximal end of the core wire at the location of the fracture was protruding from the outer catheter.The catheter was not separated from the distal tip.Functional/performance evaluation: functional testing could not be performed due to the poor sample condition (i.E.Fractured core wire).Photo review: one electronic photo was returned and reviewed by bpv field assurance engineer derrick loud.The photo shows the distal ends of a crosser rx catheter.The photo shows a complete core wire fracture near the distal tip of the catheter.A portion of the core wire is protruding from the outer catheter.The distal portion tip is still attached to the catheter and the outer catheter does not appear to be separated from the distal tip.Based upon the photo provided, a complete core wire fracture can be confirmed and material separation can be unconfirmed.Conclusion: the investigation is confirmed for a core wire fracture, as a complete fracture in the core wire was found within the catheter.The investigation is confirmed for a torn catheter at the location of the core wire fracture.The investigation is unconfirmed for material separation, as the distal tip was not separated from the catheter.The definitive root cause for this event could not be determined based upon the available information.Labeling review: the current ifu (instructions for use) states: warnings and precautions: when using the crosser in tortuous anatomy, the use of a support catheter is recommended to prevent kinking or prolapse of the crosser catheter tip.Kinking or prolapse of the tip could cause catheter breakage and/or malfunction.Interventional use: slowly advance the catheter tip through the lesion.Apply steady, constant pressure so the tip of the catheter is engaged to the lesion.Upon successful recanalization of the lesion, advance the guidewire distal to the lesion and then withdraw the crosser 14p, 14s, or 18 catheter.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.
