Event Description
|
The healthcare professional reported that during an endovascular embolization procedure, the 4.5mm x 22mm enterprise® vascular reconstruction device (enc452212 / 7212911) was impeded in the distal end of the 150cm x 5cm prowler select plus microcatheter (606s255x /(b)(4)) and could not pass though the microcatheter.The physician removed the microcatheter and the stent from the patient and switched to new devices to complete the procedure.There was no report of any negative patient impact.Additional information was received on 07-dec-2023.Per the information, the procedure was targeting the ophthalmic artery segment in a 72-year-old male patient.When the stent was removed from the patient, it was still on the delivery wire.In response to whether the stent/stent delivery system appear damaged, the response received was ¿the stent was impeded [and] could not pass through the microcatheter.¿ a continuous flush had been maintained through the microcatheter.There were no visible kinks nor other damages observed on the microcatheter.Nothing unusual was noted about the system prior to use.The replacement stent was another 4.5mm x 22mm enterprise® vascular reconstruction device (enc452212).The replacement microcatheter was another 150cm x 5cm prowler select plus microcatheter (606s255x).The information confirmed there was no negative patient impact.There was no clinically significant delay in the procedure as a result of the reported issue.

Manufacturer Narrative

Manufacturer¿s ref.No: (b)(4).The purpose of this mdr submission is to report the investigation finding of the returned device.The complaint device was returned for evaluation and analysis.The investigation finding is documented below.Investigation summary: a non-sterile 4.5mm x 22mm enterprise® vascular reconstruction device was received contained in the decontamination pouch.Visual inspection was performed.It was noted that only the delivery stent was returned for evaluation; it was observed to be in good condition (i.E., no kinks, no bends, nor elongations).The issue regarding a stent being impeded in the distal end of the microcatheter cannot be evaluated through functional testing since only the delivery wire was returned for evaluation.The stent must be inside the introducer tube to perform the functional analysis.Additionally, the returned component did not present damages that suggest that it was forcibly advanced.With the limited information available, a conclusive cause cannot be determined; however, it is possible that clinical and procedural factors, including device manipulation and operator's technique, may have contributed to the reported failure.At this time, there is no evidence to support that the issue reported in the complaint is a result of a defect inherently related to the device.The stent detachment was not originally reported in the complaint and it is suggested that occurred during the post-operative handling or decontamination of the device since it was reported that when the stent was removed from the patient, it was still on the delivery wire.If additional information or components are received at a later time, this investigation will be reassessed accordingly.Lake region medical performed a review of the device history records relative to the manufacturing, inspection, and packaging of the lot 7212911.The history record indicates this product was final inspection tested at lake region medical and was determined to be acceptable.As part of the cerenovus quality process, all devices are manufactured, inspected, and released to approved specifications.It should be noted that product failure could be caused by multiple factors.The instructions for use (ifu) does contain the following recommendations: if resistance is met during manipulation, determine the cause of resistance before proceeding.Do not apply undue force if resistance is encountered at any point during stent manipulation.Withdraw the unit and advance a new one.Based on the manufacturing documentation review, there is no indication that the event is related to the device manufacturing process.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective / preventive action may be triggered at a later time.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no corrective actions will be taken at this time.This is one of 2 products involved with the reported complaint.The associated manufacturer report numbers are: 3008114965-2023-00908 and 3008114965-2023-00909.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
