Event or Problem Description
As reported by a health care professional, this was a coil embolization of a left middle cerebral artery (mca) aneurysm that had recanalized from a prior clipping procedure.The following three cerepak coils detached: fcx100412, scr122505 and xcr120202.The fourth/final coil, a freeform mini 1.5mm x 4cm (mcr091540, (b)(6)) failed to detach.The physician was using the manual break method.Microcatheter used was an sl-10, stent was an atlas.There were no procedural delays.The procedure was successfully completed.Additional event information received on 18-mar-2025 indicated that there was no resistance during advancement of the device through the microcatheter or positioning difficulty in the aneurysm.There was no damage to the embolic coil or any device component.The vessel was not excessively tortuous or with acute bends.There was no patient injury.After the coil did not detach, the user decided to stop adding any more coils.The physician is unsure of caused the failure to detach.He has approximately 20 cerepak coils and has never had an issue before.
Additional Manufacturer Narrative
Manufacturer ref#: (b)(4).Updated sections on this medwatch: b4, d9, g3, g6, h2, h3 and h11.The product has been returned for evaluation and testing; however, the engineering evaluation has not been completed.A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.
Additional Manufacturer Narrative
Manufacturer ref#: (b)(4).Complaint conclusion: as reported by a health care professional, this was a coil embolization of a left middle cerebral artery (mca) aneurysm that had recanalized from a prior clipping procedure.The following three cerepak coils detached: fcx100412, scr122505 and xcr120202.The fourth/final coil, a freeform mini 1.5mm x 4cm (mcr091540, 31354258) failed to detach.The physician was using the manual break method.Microcatheter used was an sl-10, stent was an atlas.There were no procedural delays.The procedure was successfully completed.Additional event information received on 18-mar-2025 indicated that there was no resistance during advancement of the device through the microcatheter or positioning difficulty in the aneurysm.There was no damage to the embolic coil or any device component.The vessel was not excessively tortuous or with acute bends.There was no patient injury.After the coil did not detach, the user decided to stop adding any more coils.The physician is unsure of caused the failure to detach.He has approximately 20 cerepak coils and has never had an issue before.The device was returned to j&j medtech for further evaluation.A non-sterile freeform mini 1.5mm x 4cm was received contained in the decontamination pouch.Upon receiving the device, visual inspection was performed, and the manual break was activated at the proper location.The proximal end of the puller wire was exposed and attached to the inner tube.The embolic coil was still attached to the delivery unit, as described in the event.Microscopic inspection revealed several stretched and kinked conditions on the embolic coil.The proximal key engagement was occluded with dried residues.A manufacturing record evaluation was performed for the finished device 31354258 number, and no non-conformance's related to the malfunction were identified.The issue reported regarding the failure to detach is confirmed based on the attached condition of the embolic coil to the delivery unit after activating the manual break.The occluded condition of the proximal key engagement suggests that the saline flush could had been insufficient, since according to risk documentation, an insufficient continuous saline flush can increase resistance / friction between microcoil system and the microcatheter resulting in accidental mechanical product damage which can lead to a potential degradation of device performance due to embolic coil damages such as kinking and stretching.There is no indication that the issues reported in the complaint result from a defect inherently related to the cerepak device.As part of j&j medtech quality process all devices are manufactured, inspected, and released to approved specifications.Since there was no evidence to suggest the event was related to a manufacturing or design issue, no capa activity is required.The instructions for use (ifu) contain the following recommendations: 1.Remove the detacher from the protective packaging and place it within the sterile field.The detacher is packaged separately for single patient use only.2.Confirm again under fluoroscopy that the coil alignment marker of the delivery tube creates a ¿t¿ with the proximal marker of the microcatheter.3.Verify that the rhv is firmly locked around the delivery tube to ensure that the coil does not move during connection process.Ensure the delivery tube is straight between the rhv and the detacher.4.Hold the delivery tube approximately 3 inches from proximal end and bring the detacher over the delivery tube until a firm stop is felt.5.Maintain the delivery tube position within the detacher and use a thumb to pull back the slider on the detacher.6.Continue to pull on the slider until end of travel or a click is heard.Gently release the slider until it returns to starting position or a second click is heard.Remove detacher by slowly withdrawing it from the delivery tube.Note: detacher must remain in sterile field until the procedure is completed.7.Fluoroscopically verify that the coil is detached by gently pulling back the delivery tube approximately 1cm.If the coil has detached, remove the delivery tube from the microcatheter.8.If the coil has not detached, repeat steps 3-7.If 2 unsuccessful detachments occur, discard the detacher and proceed to the manual break section.9.Repeat steps 1-8 until the procedure is completed.Discard the detacher.Caution: always perform fluoroscopic verification of detachment prior to withdrawing the delivery system fully.Failure to do so may lead to an embolic complication.10.After detaching the coil, remove the delivery tube from the microcatheter and discard.11.Repeat the above sequence for all additional coils until the procedure is complete.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.
