Event Description

It was reported that there was an unretrieved device fragment.A 22x60 embold fibered coil was selected for use in the embolization of a splenic artery pseudoaneurysm.The anatomy was moderately tortuous.The coil was advanced through a 2.4fr non-boston scientific microcatheter.While positioning the coil into the pseudoaneurysm, there were quite a few turns, and the coil was not advancing smoothly and began buckling.The physician then tried to pull the coil back out, but it separated.Under fluoroscopy, a "long string of something, some kind of wire, fiber thing" was observed that went all the way down to the groin.The coil was snared, but while doing so, one whole piece broke off.Most of the device was retrieved, but there was still a piece that goes from the pseudoaneurysm through the splenic artery out into the celiac and about 5cm out into the abdominal aorta.The physician did not think this will cause an issue as it was not flow-limiting or causing any obstruction.Flow was still good.The radiopaque part of the coil was mostly in the splenic artery, and there's a less radiopaque part that is very thin and soft which hangs out into the celiac/aorta.Approximately 20-30cm was removed, but the last part was unable to be retrieved.The procedure was completed with a non-boston scientific coil.No further patient complications were reported, and the patient is expected to fully recover.

Manufacturer Narrative

Device eval by manufacturer: the 22x60 embold fibered coil was returned for analysis.The delivery sheath, delivery wire, and a severely damaged, stretched, and tangled coil were returned.Visual and microscopic analysis was conducted.The perforations were intact.The delivery wire was inside of the delivery sheath.The distal and proximal couplers were attached to the delivery wire via the pull wire.No damage on the delivery sheath or delivery wire was noticed.The couplers showed slight bends.The coil was severely stretched and tangled, and there were multiple breaks on the coil wire.The stretched coil was not connected to the distal coupler.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.
