Event or Problem Description
It was reported that during a coil embolization to the internal carotid artery (ica), a uniform 5mm x 9.7 cm coil (fcx100509, 31218796), a freeform mini 2mm x 3cm coil (mcr092030, 31349399) and a freeform mini 2mm x 3cm coil (mcr092030, 31077163) did not detached with manual break method.Additional event information received on 27-feb-2025 indicated that a prowler lpes microcatheter was used.Seven coils were previously planted with no issues.There had been no resistance during advancement of the device(s) through the microcatheter or positioning difficulty in the aneurysm.There were no attempts made using the detachment handle.There was no coil damage.This was a tortuous vessel with wide neck defect.The three minutes procedural delay was not clinically significant.All three coils had to be resheathed.
Additional Manufacturer Narrative
Manufacturer ref#: (b)(4).Section b5: additional event information received on (b)(6) 2025 noted that the physician¿s thinks that caused the failure to detach was a bend in the system somewhere.We believe it was due to the prowler microcatheter being bent when trying to deploy.There was nothing wrong with the microcatheter (mc).The coil tubing disconnected, and the filament was exposed.The physician has been in-service on proper technique moving forward.Complaint conclusion: it was reported that during a coil embolization to the internal carotid artery (ica), a uniform 5mm x 9.7 cm coil (fcx100509, (b)(6)), a freeform mini 2mm x 3cm coil (mcr092030, (b)(6)) and a freeform mini 2mm x 3cm coil (mcr092030, (b)(6)) did not detached with manual break method.Additional event information received on 27-feb-2025 indicated that a prowler lpes microcatheter was used.Seven coils were previously planted with no issues.There had been no resistance during advancement of the device(s) through the microcatheter or positioning difficulty in the aneurysm.There were no attempts made using the detachment handle.There was no coil damage.This was a tortuous vessel with wide neck defect.The three minutes procedural delay was not clinically significant.All three coils had to be resheathed.Additional event information received on 17-mar-2025 noted that the physisicna¿s thinks that caused the failure to detach was a bend in the system somewhere.We believe it was due to the prowler microcatheter being bent when trying to deploy.There was nothing wrong with the microcatheter (mc).The coil tubing disconnected, and the filament was exposed.The physician has been in-service on proper technique moving forward.A non-sterile freeform mini 2mm x 3cm coil was received contained in the decontamination pouch.Upon receiving the device, visual inspection was performed, the embolic coil was not attached to the delivery unit and it was not returned for evaluation.The manual break was attempted, and the proximal end of the puller wire was exposed.A manufacturing record evaluation was performed for the finished device (b)(6) number, and no non-conformances related to the malfunction were identified.The issue reported regarding the failure to detach the embolic coil is not confirmed, as no coil was attached to the delivery unit.There may have been other circumstances or issues that occurred during the use of the device that could not be replicated during the analysis.There is no indication that the issue reported in the complaint is a result of a defect inherently related to the device.As part of j&j medtech 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) 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.
