During a percutaneous transluminal angioplasty (pta) shunt case, when a guide wire was inserted into a 5mm6cm 150 saber pta the guidewire penetrated between the balloon and its distal tip.Therefore the balloon catheter was replaced with a new balloon catheter.The procedure finished successfully.There was no reported patient injury.The product will be returned for analysis. the target lesion was the shunt.The patient¿s vessel level of tortuousness and calcification was unknown.The rate of stenosis was unknown. there was no difficulty removing the product from the hoop, no difficulty removing the protective balloon cover and no difficulty removing the stylet or any of the sterile packaging components. there were no kinks or other damages noted prior to inserting the product the product into the patient. there was no difficulty inserting the device onto the wire. additional procedural details were requested but are unknown.

During a percutaneous transluminal angioplasty (pta) shunt case, when a guide wire was inserted into a 5mm6cm 150 saber balloon catheter (bc), the guidewire penetrated between the balloon and its distal tip.Therefore the balloon catheter was replaced with a new balloon catheter.The procedure finished successfully.There was no reported patient injury.The target lesion was the shunt.The patient¿s vessel level of tortuousness and calcification was unknown.The rate of stenosis was unknown.Additional information was received that there was no difficulty removing the product from the hoop, no difficulty removing the protective balloon cover and no difficulty removing the stylet or any of the sterile packaging components.There were no kinks or other damages noted prior to inserting the product the product into the patient.There was no difficulty inserting the device onto the wire.Additional procedural details were requested but are unknown. one non-sterile catheter saber 5mm4cm 90 was received coiled inside a plastic bag.Per visual analysis the distal tip area presented a fractured/separation condition at.3mm.No other anomalies/damages were found on the received unit.Sem results showed that the characteristics observed on the rupture point of both sides of the tip separation leads to the same failure mode.The pattern of trail lines observed on the diameter surfaces at the rupture\separation point indicate that a mechanical cutting might be the cause of the mentioned separation.The exact kind of tool is unknown.Review of lot 17477982 revealed no anomalies during the manufacturing and inspection processes. the reported ¿body/shaft- puncture/cut - during prep¿ was not confirmed through analysis; however, it was noted that the distal tip presented a fractured/separated condition.The exact cause of the failure reported by the customer as well as the separation of distal tip found could not be conclusively determined.However, based on the sem results, procedural factors likely contributed to the conditions reported.According to the instructions for use (ifu), ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.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.¿ 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/preventive action will be taken.
