It was reported that tae (trans arterial embolization ) was performed for cha (common hepatic artery) aneurysm.During procedure resistance was encountered when the subject coil was attempted to be placed inside the aneurysm from a non-stryker microcatheter breakthrough.Therefore, the subject coil was retrieved, resulting prematurely detached within the microcatheter.The physician replaced it with a new device and continued the procedure without clinical consequences to the patient.

H4 manufacturing date ¿ added.D4 expiration date - added.Due to the automated mes (manufacturing execution system) system there are controls in the manufacturing process to ensure the product met specifications upon release.The subject device was not available; therefore, a visual inspection as well as a functional evaluation could not be performed.The reported event is covered in the device directions for use (dfu).As well, the risk of the reported event is documented in the risk documentation and there are current controls to mitigate the risk of the as reported event.The reported complaint could not be confirmed, and it could not be definitively determined if the device failed to meet specifications because the product was not returned.Additional information provided by the customer indicated that the device was confirmed to be in good condition during preparation/prior to use on the patient and was prepared for use as per the dfu, continuous flush was set up and maintained throughout the clinical procedure, the tortuosity of the patient's anatomy was normal, a non-stryker microcatheter was used with the subject coil, the tapered distal end of the introducer sheath was firmly seated in the hub of the microcatheter, the rhv was adequately tightened while the introducer sheath was in the hub (not over/under-tightened) and was opened enough to allow passage of the device through without damage, no torque was given where advancing the delivery wire, the coil was advanced slowly and gently without applying excessive force, and resistance was encountered at the distal of the microcatheter.While there are a number of potential causes for the reported issue, because review of available information failed to identify a definitive cause and the device was not returned for analysis, an assignable cause of undeterminable was assigned to this complaint.
