During preparation, a 4x200mm saber balloon catheter tip came off.A new saber balloon catheter was used to complete the procedure.There was no patient injury.There was no damages noted to the device packaging.There was no force used when the device was removed from the packaging.There was no difficulty removing the product from the hoop, the protective balloon cover, the stylet or any of the sterile packaging components.One non-sterile unit of saber 4mm20cm 90 was received coiled inside a plastic bag.Per visual analysis, the balloon was previously inflated/deflated, the distal tip of the balloon device was found separated.No damages were noted in the device.The separated tip was inspected under microscope and it was noticed that the separated edges presented evidence of elongation.Unit was sent to sem analysis and results showed that the distal and proximal sections of the separated tip presented evidence of elongations.The elongations observed suggests that the device was induced to stretching/pulling events that exceeded the material¿s yield strength prior to the separation.No other issues were noted during sem analysis.A device history record (dhr) review of lot 17483975 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 product analysis.However, the exact root cause of the separated condition could not be conclusively determined.Based on the information available for review, procedural/handling factors may have contributed to the event reported as evidenced by elongations found during sem analysis.According to the instructions for use ¿if resistance is felt upon removal, then the balloon, guidewire and the sheath should be removed together as a unit, particularly if balloon rupture or leakage is known or suspected.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 dhr review nor the product analysis suggests that the event experienced by the customer could be related to the manufacturing process.Therefore, no corrective and preventive actions will be taken at this time.
