Additional Manufacturer Narrative
Manufacturer's reference number: (b)(4).Information regarding patient weight, height, medical history, race, and ethnicity was not reported.Since no device has been received for analysis, no product investigation can be performed and the reported failure could not be evaluated.A device history review (dhr) associated with this lot presented no issues during the manufacturing or inspection process that can be related to the reported complaint.Cerebral hemorrhage is a known potential complication associated with the use of the embotrap iii device and is mentioned in the instructions for use (ifu) as such.There was no alleged quality issue related to the used device, as the device performed as intended.There are clinical and procedural factors, including vessel characteristics, device interaction, and operator technique, that may have contributed to the reported event rather than the design or manufacture of the device.It was reported that alternative factors, such as the administration of tissue plasminogen activator (tpa), may have contributed to the hemorrhagic event; however, the exact cause remains unknown.Hemorrhagic complications following thrombectomy procedures may result from multiple factors, including reperfusion injury, pharmacological factors, and vessel injury.Based on the information provided, a device-related cause cannot be ruled out nor confirmed.Given that the serious adverse event (hemorrhage with associated neurological deficits) occurred in temporal association with device use, and in the absence of a confirmed alternative cause, this event does meet us fda reporting criteria under 21 cfr 803 with a classification of a ¿serious injury,¿ with an awareness date of 02-apr-2026.The file will be re-reviewed if additional information is received at a later date.As part of the post market surveillance program, information from this complaint is trended to identify statistical signals for consideration of further correction action.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.Missing information from this report is identified as blank; this information was not provided in the reported event or available at the time of report submission.The company is seeking this information through the event investigation.This report is being submitted pursuant to the provisions of 21 cfr, part 803.This report may be based on information which has not been investigated or verified prior to the required reporting date.This report does not reflect a conclusion by cerenovus, or its employees that the report constitutes an admission that the product, cerenovus, or its employees caused or contributed to the potential event described in this report.If information is obtained that was not available for the initial report, a follow-up report will be filed as appropriate.
Event or Problem Description
It was reported, via a personal interaction, that an embotrap iii 5 mm x 37 mm (et309537/25k286av) was used for a mechanical thrombectomy of the middle cerebral artery m1 occlusion to treat cerebral infarction, which was performed by combined technique.During the procedure, successful recanalization (tici 3) was achieved in one pass; however, a postoperative hemorrhagic complication was observed.The patient was left with residual neurological deficits.No further treatment is planned.The physician commented that although it is unclear whether there is a causal relationship with embotrap iii, a postoperative hemorrhagic complication was observed.Potential causes other than the embotrap iii was reported as "the effect of tpa may be considered; however, this remains uncertain." continuous flush was not done.Another device used during the procedure was a cereglide71 intermediate catheter.The event was initially reported as such, "the procedure was a mechanical thrombectomy of middle cerebral artery m1 occlusion to treat cerebral infarction, which was performed by combined technique.The devices were used according to ifu.Using the embotrap iii with a combined technique, successful recanalization (tici 3) was achieved in 1 pass.A postoperative hemorrhagic complication was observed.The patient was left with residual neurological deficits.Neurological deficits remained.No further treatment is planned.Physician¿s comment on the relationship between this event and the product: although it is unclear whether there is a causal relationship with the embotrap iii, a postoperative hemorrhagic complication was observed.As potential causes other than the embotrap iii, the effect of tpa may be considered; however, this remains uncertain.Continuous flush was not done.The lesion was middle cerebral artery m1.Other concomitant device was ceregride 71 intermediate catheter.".
