Event Date 05/27/2023

Event Type  Injury  

Event Description

It was reported that the coil fractured within the patient, and additional intervention was unable to retrieve all fragments of the coil.An embold fibered detachable coil system was selected for use in the embolization procedure to treat bleeding within a visceral artery.This was intended to be the last coil placed via a non-bsc catheter, after placing another embold coil.The end of the embold coil was reported to be bent and there was visible coupling wire pulled back.The physician thought the coil was outside the microcatheter tip, and tried to pull back the nitinol wire, but the coil was still attached.The coil was advanced again, more of the nitinol wire was pulled back, but the coil was still attached.The physician then decided to remove the coil from the microcatheter and the patient.It was not confirmed the coil was outside the microcatheter.The microcatheter was flushed with no issue under fluoroscopy.Another coil was opened, and upon insertion, it was discovered the previous coil was still in the microcatheter.Since the microcatheter had moved back, the second coil was pushed into a non-target location.The replacement coil was removed and not deployed.The physician attempted to snare the second embold, but the coil kept breaking apart.A portion of the coil was able to be snared successfully, and the portion of the coil that remained in the patient was able to be pushed partially into the existing coil nest.The tail end of the coil extended to a more proximal portion of the target vessel and may have covered a side branch of the visceral vessel unintentionally.A greater portion of the vessel was embolized than intended.However, the intended vessel occlusion was successful, and the patient was reported to have recovered fully.

Manufacturer Narrative

Corrected: h6 - impact codes: the impact codes of f15: recognized device or procedural complication and f10: inadequate/inappropriate treatment or diagnostic exposure were updated to f0103: unexpected therapeutic effects.Device analysis: the delivery wire was returned.No other components were returned for analysis.The returned delivery wire showed the polymer shaft was attached as well as the proximal coupler.The proximal coupler component was not damaged.The perforations were broken, and the pull wire was pulled completely out of the delivery wire.Inspection of the remainder of the device revealed no damage or irregularities.The complaints of kinks on the main coil, breaks on the coil, or delayed separation were unable to be confirmed due to the components not returning for analysis.
