It was reported that during an endovascular procedure in a patient with internal carotid artery aneurysm, the subject coil got stuck in the microcatheter, the physician removed the subject coil together with the microcatheter out of the patient vasculature.The physician deployed a flow diverter stent and then attempted to deploy coil from posterior circulation.There was a surgical delay of 1 hour and it was reported that the patient experienced unknown adverse consequences due to the surgical delay.No further information is available.

H4 manufacturing date ¿ added.H3 device evaluated by mfg ¿updated.H3 summary attached - updated.D4 expiration date - added.D9 product available to stryker ¿ updated.D9 returned to manufacturer on ¿updated.Due to the automated manufacturing execution system (mes) there are controls in the manufacturing process to ensure the product met specifications upon release.The device was returned and the lot number was confirmed with the packaging.During visual/microscopic inspection, the main coil was found to be stuck in a non-stryker catheter.The main coil was found to be detached/separated.The main coil was found to be kinked/bent and stretched.The coil delivery wire was found to be kinked/bent.The coil introducer sheath was not returned.During functional inspection, the catheter was flushed, and a mandrel was advanced through it, pushing the detached coil out of the catheter.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 coil jammed was confirmed during analysis.The reported patient complications could not be confirmed as the event is procedure/patient related.The device failed to meet specifications when received for complaint investigation based on the analyzed anomalies noted to the device.Additional information provided by the customer was the coil got stuck in the microcatheter.The device was prepared as per the dfu.Also, additional information indicated that continuous flush was set up and maintained throughout the clinical procedure.The device was returned and the coil was found to be detached and jammed within a non stryker catheter, the coil was removed from the catheter during device analysis and was found to be kinked and stretched, the delivery wire was returned and found to be kinked/bent.The introducer sheath was not returned.In the case of this complaint it is most likely that when the device encountered difficulties during the clinical procedure, the damage caused to the delivery wire and main coil was due to handling and manipulation of the device, causing the coil to prematurely detach and jam within the catheter.Therefore the as reported and as analyzed event of 'coil jammed' and the as reported event of 'patient complications' as well as the as analyzed event of 'main coil prematurely detached/separated during use', 'main coil stretched', 'main coil kinked/bent' will be assigned procedural factors as this complaint appears to be associated with a product that met stryker design and manufacturing specifications and was used in accordance with the dfu, but performance was limited due to procedural factors during use.An assignable cause of handling damage will be assigned to the as analyzed event of 'coil delivery wire kinked/bent' as the issue is associated with handling of the device during the clinical procedure, upon removal of the device from the packaging, or preparation of the device prior to use.
