Complaint conclusion: the tip of a saber balloon catheter (4mm x 15cm x 150cm) fell off during prep.The device was not clinically used and there was no reported patient injury.The product was opened in a sterile field and stored as per labeling.The device was not used in the patient.There were no anomalies noted to the device when it was taken out of the packaging.The product was prepped properly according to the ifu.The device did not prep normally; the tip fell off when injecting saline.The device did not kink in the area of separation.One product was returned for analysis.A non-sterile saber 4mm x 15cm x 150cm was returned.Per visual analysis the balloon catheter was coiled inside of a clear plastic bag with the balloon deflated.A separation was noted at the distal tip.No other damages or anomalies were observed on the returned product.Per sem analysis, the saber tip separation was observed on pictures.The soft tip (blue tip) that separated, was not received for analysis.Results showed that the analyzed section of the mating sites, where the soft tip is fused to the balloon and inner body, presented evidence of elongations.The elongations suggest that the tip was induced to stretching/pulling events that exceeded the tip material yield strength prior to the separation.No other issues were noted during sem analysis.A product history record (phr) review of lot 17685990 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿distal tip - separated during prep¿ was confirmed through analysis of the returned device.The exact cause of the separation could not be conclusively determined.However, analysis revealed elongations suggesting the tip was induced to stretching/pulling events that exceeded the tips material yield strength prior to the separation.Therefore, procedural or handling factors may have contributed to the reported event.According to the safety information in the instructions for use ¿proper functioning of the catheter depends on its integrity.Care should be used when handling the catheter.Damage may result from kinking, stretching, or forceful wiping of the catheter.Forceful handling can result in catheter separation and the subsequent need to use a snare or other medical interventional techniques to retrieve the pieces.Always verify integrity of the catheter after removal.¿ neither the phr review nor the product analysis suggests that the found damages could be related to the manufacturing process of the unit.Therefore, no corrective or preventive actions will be taken at this time.
