Event Description

A report was received that during a coil embolization, the 2.5mm x 6cm ultipaq 10 (fsr10025620/c27367) and 3mm x 4cm cashmere 14 (crc14030430/s10171) coils could not be deployed.The coils were removed easily without the need for additional intervention.The coils were replaced, and the procedure was completed successfully.The surgery was not delayed due to the event.No patient complications occurred as a result of the event.The products will be returned for evaluation.No further information was provided.

Manufacturer Narrative

Product complaint # (b)(4).The purpose of this mdr submission is to report that the product has been returned for evaluation and testing; however, the engineering evaluation has not been completed.A review of the manufacturing documentation associated with this lot presented no issues during the manufacturing or inspection process that can be related to the reported complaint.No non-conformances related to the reported complaint condition were identified.Additional information will be submitted within 30 days of receipt.A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.This is one of two products involved with the complaint and the associated manufacturer report numbers are 3008114965-2019-00867 & 3008114965-2019-00868.

Manufacturer Narrative

Product complaint # (b)(4).Additional information received indicated that there was resistance/friction encountered as the coils were advanced through the microcatheter and the coils were unable to be deployed.The coils were successfully removed from the patient without need for additional intervention.The embolic coils were still attached to the delivery system when removed, but the embolic coils appeared damaged upon removal.The user did not apply undue force when handling the devices.The size and brand of the concomitant microcatheter was not reported.Prior to these coils, other coils were able to be advanced through the same microcatheter without resistance.No further information could be obtained.Device code - remove "separation failure" (2547) as the reported issues were resistance/friction, deployment difficulty, and coil damage, not that the coils failed to detach.The product has been shipped for evaluation and testing; however, it has not been received to date.Additional information will be submitted within 30 days of receipt.The manufacturer will submit a supplemental report if new facts arise which materially alter information submitted in a previous mdr report.This is one of two products involved with the complaint and the associated manufacturer report numbers are 3008114965-2019-00867.

Manufacturer Narrative

(b)(4).It was reported that during a coil embolization, there was resistance/friction encountered when the 2.5mm x 6cm ultipaq 10 (b)(4) and 3mm x 4cm cashmere 14 (b)(4) were advanced through the unspecified microcatheter and the coils were unable to be deployed.The coils were removed successfully from the patient without the need for additional intervention.The embolic coils were reportedly still attached to the delivery system when removed, but the embolic coils appeared damaged.The coils were replaced, and the procedure was completed successfully.The surgery was not delayed due to the event.No patient complications occurred as a result of the event.The products will be returned for evaluation.No further information was provided.The user did not apply undue force when handling the devices.Prior to these coils, other coils were able to be advanced through the same microcatheter without resistance.No further information could be obtained.A non-sterile 3mm x 4cm cashmere 14 was received inside of a pouch.Upon receipt of the complaint device, visual inspection was conducted.The device positioning unit (dpu) core wire and hub connector were found undamaged.The resheathing tool was seen without damage.The v-notch of the sheathing tool was undamaged.The introducer was found completely unzipped and kinked.The embolic coil was seen inside the introducer sheath.There were no other visual anomalies observed during the visual inspection.The device was then examined under a microscope.The articulating joint was intact.No damage was found at any point in the embolic coil.The embolic coil distal ball tip was present and intact.The distal outer sheath was seen intact indicating that the resistance heating (rh) coil had not heated, and the detachment process had not been initiated.The device was connected to multimeter and the resistance was measured within specification.The device was then connected to a lab detachment control box (dcb) and standard connecting cable.The dcb power was turned on and the system ready light illuminated.The embolic coil was immersed in warm enzyme solution and the detach button was pressed.The embolic coil detached.Microscopic evaluation indicated that the rh coil had heated.Advancement through a lab microcatheter could not be tested due to the condition of the returned device.A review of manufacturing documentation associated with this lot presented no issues during the manufacturing or inspection processes related to the reported complaint.No non-conformances related to the reported complaint condition were identified.The customer report of resistance/friction during advancement through the microcatheter and deployment difficulty could not be evaluated because the kinked condition of the introducer prevented functional analysis.The customer report of coil damage was not confirmed since no damage was seen on the embolic coil.The exact circumstances surrounding the observed kink on the introducer cannot be determined based on the condition of the returned device; however, it is likely that excessive force was applied to the device.100% of devices are inspected for damage at quality control (qc) final inspection.Thus, it is very unlikely that the device left the manufacturing facility with the observed damage.Functional testing could not be performed to determine potential causes of the resistance during advancement and deployment difficulty.Resistance/friction, deployment difficulty, and coil damage are known potential failures associated with the use of the device.The instructions for use (ifu) contains several cautions relating to these situations, including instructions for troubleshooting the situations should they be encountered during use.The ifu states the following: ¿if unusual friction is still noticed during advancement or retraction of the microcoil system, verify flush lines are open and properly pressurized.Then slowly withdraw the entire microcoil system and examine for damage.Replace it with a new microcoil system.If friction still exists, withdraw and examine the delivery catheter system.If the microcoil system becomes immobile in the infusion microcatheter, apply a gentle push-pull motion to free it.If unsuccessful, remove both microcatheter and microcoil system together as a unit and replace with new devices.¿ neither the device history record review nor the product analysis suggests that the reported failures could be related to the manufacturing process of the unit.Assignment of root cause for the event remains speculative and inconclusive, based on the minimal information provided and the evidence presented by the sample article; however, it is possible that procedural and handling factors, including device manipulation and interaction with the concomitant microcatheter, may have contributed to the reported failures and damage noted to the introducer.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.A supplemental report will be submitted if new facts arise which materially alter information submitted in a previous mdr report.This is one of two products involved with the complaint and the associated manufacturer report numbers are 3008114965-2019-00867 & 3008114965-2019-00868.
