Event or Problem Description
As reported by the field, this was a coil embolization to a posterior communicating artery (pcom) aneurysm.The first 4 coils were deployed without an issue.The 5th coil, a freeform mini 1mm x 3cm ( mcr091030, 31140702) was situated and detachment was attempted with a mechanical detachment handler (mdh1, 102109430) which did not detach.Manual break method was then attempted, once again failing to detach at both 2cm pull and 4cm pull.Coil was removed and a 6th coil, a freeform mini 1mm x 2cm (mcr091020, 31131257) was positioned.After attempting and failing detachment with handle manual break method was utilized again.The coil still failed to detach and was therefore removed.Case was completed with one competitive coil.There was a 10-minute procedural delays due to the event.The procedure was successfully completed.Additional event information was received on 24-jun-2024 indicating that a phenom 17 150cm microcatheter was used.There was no resistance during advancement of the devices through the microcatheter or positioning difficulty in the aneurysm.There was no damage to the embolic coil or any device component.The vessel was moderately tortuous, nothing ¿extreme¿ per the physician.The events did not result in any patient injury.The physician felt that the procedural delayed completion of case and need to remove coil increased risk of disrupting coil mass.
Additional Manufacturer Narrative
Product complaint # (b)(4).Updated sections on this med watch: b4, d4 (primary udi number), g3, g6, h2, h3, h6 and h11.Complaint conclusion: as reported by the field, this was a coil embolization to a posterior communicating artery (pcom) aneurysm.The first 4 coils were deployed without an issue.The 5th coil, a freeform mini 1mm x 3cm ( mcr091030, 31140702) was situated and detachment was attempted with a mechanical detachment handler (mdh1, 102109430) which did not detach.Manual break method was then attempted, once again failing to detach at both 2cm pull and 4cm pull.Coil was removed and a 6th coil, a freeform mini 1mm x 2cm (mcr091020, 31131257) was positioned.After attempting and failing detachment with handle manual break method was utilized again.The coil still failed to detach and was therefore removed.Case was completed with one competitive coil.There was a 10-minute procedural delays due to the event.The procedure was successfully completed.Additional event information was received on 24-jun-2024 indicating that a phenom 17 150cm microcatheter was used.There was no resistance during advancement of the devices through the microcatheter or positioning difficulty in the aneurysm.There was no damage to the embolic coil or any device component.The vessel was moderately tortuous, nothing ¿extreme¿ per the physician.The events did not result in any patient injury.The physician felt that the procedural delayed completion of case and need to remove coil increased risk of disrupting coil mass.A non-sterile freeform mini 1mm x 2cm was received contained in the decontamination pouch.Upon receiving the device, visual inspection was performed, and the embolic coil was not attached to the delivery system.The manual break was attempted, and 11.5 cm of puller wire were exposed.The embolic coil was not returned for evaluation.Microscopic inspection on the distal end of the device showed no damages on the support coil.A manufacturing record evaluation was performed for the finished device 31131257 number, and no non-conformances related to the malfunction were identified.The issue reported regarding the failure to detach the embolic coil was not confirmed due to the broken condition of the manual break and detached condition of the embolic coil.There may have been other circumstances or issues that occurred during the use of the device that could not be replicated during the analysis.The appearance of the returned device does not suggest that it was subjected to excessive force to overcome the friction with the microcatheter.As part of cerenovus quality process all devices are manufactured, inspected, and released to approved specifications.Since no issues were identified, no capa activity is required.The instructions for use (ifu) provide the following recommendations for the manual break use: 1.Locate the manual break indicator (mbi) markers approximately 20cm from the proximal end of the device.2.Using your thumb & forefinger, grip the delivery pusher with one hand precisely at the center of each of the mbi markers.3.Bend the proximal end of the pusher between the mbi markers approximately 90 degrees or until the tube snaps.If needed, continue bending and straightening until the tube separates and exposes the internal pull-wire.4.Ensure the proximal portion of the delivery tube is in line with the remaining tube.While holding the distal end, pull the proximal end approximately 2-3cm to release the coil.Note: if it is determined that the coil will not be detached, remove it from the microcatheter as outlined in the following section.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.A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.
