As reported by the nurse, the pig catheter broke during a case while it was inside the patient.The physician also observed that the band markers on the catheter were loose and moved.The most proximal marker also moved.There was no reported patient injury.The device was stored and handled per the instructions for use (ifu).There were no anomalies notes when the device was removed from the package.The device was prepped per the ifu.There were no anomalies noted during prep.There was some resistance met while withdrawing the device.The physician had to use a snare to retrieve the distal portion of the catheter out.All 20 markers were accounted for.The device did not kink in the area of separation.Additional procedural details were requested but are unknown.A non-sterile diagnostic cath mb 5f pig 110cm 6sh was received for analysis coiled inside a plastic bag.The catheter body was separated at 24.5 cm from its distal end and one of the separated sections presented a compressed condition at the separation section.Also, 1 out of 20 marker bands were found moved/ out of position at the distal section of the unit.The distal section of the unit was observed under the vision system and the marker band marks on the unit¿s surface did not present evidence of damage (scratches, peelings, abrasions, etc.).The catheter showed 1 marker band (mb 20) moved proximal from its original place.The rest of the marker bands 2 to 20 remained in their original positions (the position of the marker bands is numerated from the distal end to the hub).No other anomalies were found.Sem analysis was performed to determine the possible cause of the catheter body separation.Sem results showed that the separated sections of the outer member presented elongations and frayed edges.Also, compress condition was observed on one of the separated sections.These characteristics presented evidence as a product of an application of a tension force that induced the separation.The inner and outer diameter (id and od) of the catheter body's inner shaft was measured between marker band 1 and marker band 2 and id result was found within the minimal lower specification, however, od was found out of specification; this suggested an elongation condition in this section of the catheter.Review of lot 17610987 revealed no anomalies during the manufacturing and inspection processes that can be associated with the reported complaint. the complaint reported by the customer as ¿catheter body shaft - separated - in-patient¿ was confirmed as the product was received.The cause of the event experienced by the customer could not be conclusively determined.However, procedural factors may have contributed to the reported event as evident by elongations which could be attributed to tensile forces.According to the products instructions for use, users are warned that manipulation of the catheter under excessive friction due to interaction with other devices or while trapped in the vasculature, can lead to stretching or elongation of the catheter.Stretching or elongation of the catheter during endovascular procedures could result in the marker bands moving along the catheter.In extreme cases, marker bands may come off the catheter and dislodge into the vascular system.Neither the device history record review nor the product analysis suggests that the event is related to the manufacturing process.Therefore, no corrective or preventative actions will be taken at this time.
