As reported, the physician attempted to use a 5f pig 110cm super torque marker band (mb) diagnostic catheter however, the marker band was insufficiently bonded to the catheter shaft and showed movement.Therefore, the device was not used for the procedure.There was no reported patient injury.The physician attempted to use the catheter during a percutaneous coronary intervention (pci) procedure.Multiple attempts to obtain supplemental information were made; however, additional event details were not provided.The non-sterile cath mb 5f pig 110cm 65h unit was received coiled inside a clear plastic bag and unpacked for evaluation.Inspection confirmed that the 10 marker bands were out of position and that the marker bands from numbers 11 to 20 had shifted from their manufacturing locations, with all 20 bands present and none missing as verified from distal end to hub.Dimensional checks of id and od on the body shaft showed measurements out of specification in the region between the assigned marker band locations, attributed to band displacement and resulting deformation of the catheter body affecting both internal and external diameter.A 0.038" guidewire was inserted through the distal tip but could not traverse the entire length of the catheter, stopping near the first misaligned band due to deformation; insertion and withdrawal also failed.Vision system inspection confirmed that the marker band surfaces did not show scratches, peelings, or abrasions.Overall inspection confirmed 10 marker bands displaced and corresponding dimensional deviations due to deformation of the catheter body; however, the exact cause of the condition could not be conclusively determined, and no evidence suggested the event was related to manufacturing or design.The observed ¿marker band ¿ offset/out of position ¿ prior to/during measurement¿ was seen during the product evaluation.Stretching of the catheter could result in marker bands moving along the catheter.The information provided did not confirm user compliance with the device labeling therefore handling factors that resulted in catheter stretching cannot be excluded.Users are trained to inspect for signs of damage prior to and during use.Any product with damage is not to be used.Information for safety is provided in the products labeling with the intent of making the user aware of the risks.According to the instructions for use (ifu), although not intended as a mitigation of risk, ¿stretching or elongation of the catheter during endovascular procedures could result in the marker bands moving along the catheter.¿ based on the available information and product analysis, there is no evidence to suggest the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
