Additional Manufacturer Narrative
Based on the analysis findings, the pipeline flex was not confirmed to have failure to open at middle.The pipeline flex braid were found fully opened and moderately frayed.In addition, the middle section of the braid was found fully opened and no damage.However, the pipeline flex device was confirmed to have pushwire break/ separation.The pushwire was found to be separated proximal to the dps sleeves.Per the sem result features observed indicate the wire failed via torsional overload failure mechanism.It is likely that the patient tortuous anatomy may have contributed to this event.There was no non-conformance to specifications identified that led to the reported issue.If information is provided in the future, a supplemental report will be issued.
Event or Problem Description
Medtronic received a report that the pipeline failed to open in the middle section and was damaged.The patient was undergoing treatment for an unruptured, saccular aneurysm located in the right ophthalmic artery segment.The max diameter was 7mm, and the neck diameter was 6mm.The patient's vessel tortuosity was severe.The landing zone was 4mm distal and 4.5mm proximal.The access vessel was the femoral artery.It was reported that after the microcatheter was in place and the doctor started to deliver the pipeline it was found that the stent was kinked at the horizontal section of c4, and the anterior and posterior sites could be opened.The kink and flattened horizontal section of the stent could not be resolved by pushing and pulling the stent several times.The pipeline was repeatedly retrieved and repositioned to the distal side.After more than two resheathing attempts, it was still kinked at the c4 horizontal segment and could not be deployed normally.It was noted that there were burrs on the tip of the pipeline, so the entire pipeline and microcatheter delivery system were withdrawn.The pipeline was not positioned in a bend when the middle section failed to open, and more than 50% had been deployed at the time.After the whole set was withdrawn from the body, the assistant pulled the pipeline pushwire from the proximal end of the microcatheter so that the pipeline and developing wire at the distal end of the pushwire remained in the micro catheter.In order to remove the stent, the distal end of the microcatheter was cut, but the device was not found.Posterior fluoroscopy revealed that the stent was located in the proximal hub section of the microcatheter.The hub section of the microcatheter was removed to take out the pipeline, and the distal end of the stent was found to be rough.The device was replaced.And the patient did not experience any injury or complications.The devices were prepared and flushed according to the instructions for use (ifu).Ancillary devices include a phenom 27 microcatheter.Additional information was received.During the retrieval process of the whole system, the push wire was not detached.After the push rod and the micro catheter were all withdrawn together, it detached when pulling the push wire from the proximal end of phenom27 microcatheter in vitro, and the stent remained at the hub of phenom27 proximal end.There was friction resistance, but not very high resistance.
