Event or Problem Description
The healthcare professional reported that during an endovascular embolization procedure, two (2) 1mm x 2cm cerepak freeform mini coils (mcr091020) from the same lot (31131257) did not detach.Multiple attempts were tried with the cerepak detachment handle (mdh1 / lot# unknown).There was no report of any negative patient impact.There was no medical intervention required.The procedure was not delayed due to the reported event.
Additional Manufacturer Narrative
Manufacturer¿s ref.No: (b)(4).The purpose of this mdr submission is to report the investigation finding of the returned device.The complaint device was returned for evaluation and analysis.The investigation finding is documented below.Investigation summary: a non-sterile 1mm x 2cm cerepak freeform mini coil was received contained in the decontamination pouch.Visual inspection was performed.The embolic coil was observed still attached to the delivery system.No deformities were noted on the detachment tube.No defects were noted on the loop wire.No contamination was noted at the distal end.The pull wire broke at 14.5 cm from the manual break, and the pull wire did not translate.The manual break was not attempted.The pull wire was removed from the delivery system using an instron tester.The coil detached at 64 gram-force (gf).The pull wire was inspected, the kink feature was located at 6.5 cm, with a height of 0.0071 inches, and width of 0.0118 inches.The ablation pattern was found within specifications.The outer diameter of the pull wire was measured, and found to be 0.00186 inches, and 0.00222 inches.No visual defects were observed.No evidence of ptfe delamination nor unintentional weld was found.The peek tube was dissected from the distal and proximal end, and no evidence of glue or pebax reflow was noted.The distal inner diameter of the peek tube was measured and found to be within specifications.No contamination was found inside.The crimp of the inner and outer tubes was inspected, and the exposed length of the inner tube was found to be 3.4 cm, and it was not deformed.The proximal joint was inspected for correct welding/gluing in the welding location, and no defects were observed.The wire broke at 5.2 cm from the proximal welding location.A review of manufacturing documentation associated with this lot (31131257) presented no issues during the manufacturing or inspection processes related to the reported complaint.There were no nonconformances related to device manufacture or inspection.As part of the cerenovus quality process, all devices are manufactured, inspected, and released to approved specifications.Devices undergo 100% inspection at different points during the manufacturing process to prevent damages from leaving the facility.The issue reported regarding the embolic coil becoming fragmented was not confirmed, as such damage was not identified on the embolic coil; however, the issue reported regarding the detachment failure was confirmed due to the broke condition of the pull wire, and the attached condition of the coil.It should be noted that the manual break was not attempted.With the limited information available and the evidence obtained from the device inspection, there is no clear insight into the root cause and/or exact contributing factors that may have resulted in the observed failure mode.There is no indication that the issue reported in the complaint is a result of a defect inherently related to the device.It should be noted that product failure is multifactorial.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.Based on the manufacturing documentation review, there is no indication that the event is related to the device manufacturing process.As part of the post market surveillance program, information from this complaint is trended for statistical signals and corrective / preventive action may be triggered at a later time.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.This is one of 3 products involved with the reported complaint.The associated manufacturer report numbers are: 3008114965-2023-00795, 3008114965-2023-00796, and 3008114965-2023-00797.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.Additional information will be submitted within 30 days of receipt.
