Complaint conclusion: as reported, the 5f 110cm 6 side holes (sh) angiographic super torque pigtail marker band (mb) catheter ruptured completely during the change on a non-cordis 0.35 guide wire.A lasso recovery was performed.There was no reported patient injury.Additional procedural details were requested but not provided.The device was not returned for analysis.A product history record (phr) review of lot 17940006 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.Based on the information provided, it is not possible to draw a clinical conclusion between the device and the reported event.Without the return of the device for analysis, the reported customer event ¿catheter (body/shaft)- burst¿ could not be confirmed and the exact root cause could not be determined.Procedural/handling factors may have contributed to the reported event.Per the instructions for use, which is not intended as a mitigation of risk, ¿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.Extreme care to avoid stretching or elongation must be exercised during manipulation and withdrawal.If resistance is felt during manipulation, determine the cause of resistance before proceeding and confirm super torque® mb angiographic catheter positioning under high quality fluoroscopic observation.Do not advance or withdraw the super torque® mb angiographic catheter within the vascular system unless it is preceded by a guide wire.Exercise care when removing guidewires from multiple-curve catheters.Avoid excessive tension on the device during manipulation.¿ neither the phr review nor the information available suggests that the reported failure could be related to the manufacturing process of the unit.Therefore, no corrective or preventative actions will be taken at this time.
