Event Description
|
It was reported that stent damage and deployment difficulties occurred.The target lesion was located in a heavily calcified, long segment occlusion of the left superficial femoral artery (sfa).The lesion was prepared with predilation using a balloon catheter and a scoring balloon catheter.A 6x150 130 cm eluvia¿ drug-eluting vascular stent system was advanced contralaterally to the sfa and was able to deploy 1cm of the stent with the thumb wheel when deployment failed.The physician then "cut off the control handle" and tried to manually deploy the stent however this also failed.The eluvia¿ system was removed by advancing a 7 french, 90cm sheath over the eluvia¿ system and partially deployed stent.The system was removed and a distal part of the stent was damaged and elongated.A small piece of the stent broke and was trapped by a 6mm balloon.The procedure was completed with the deployment of 6 x 150 mm and 7 x 100 eluvia¿ stents overlapping in the occluded segment of the sfa.The procedure results "showed nicely run off." there were no patient complications reported and the patient's status was stable.

Manufacturer Narrative

Device evaluated by mfr.: returned product consisted of an eluvia self-expanding stent delivery system (sds).The outer shaft, middle shaft, inner shaft and the remainder of the device were checked for damage.The outer sheath, middle shaft and the proximal inner shaft were all separated from the device when received.The sheath showed buckling/damage approximately 30 to 31.5cm from the separated area.The outer sheath also showed 2 kinks, one at 21.5cm from the marker band and the other at 23.5cm from the marker band.The handle was opened when returned and multiple components were missing.The nosecone was not returned.The retainer clip from inside of the handle was not returned.The pull handle was completely separated from the handle.The stent was returned in the device; however, it was partially deployed approximately 12mm from the marker band and damaged.The handle was opened and it was noticed that the thumb wheel had gear damage.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).
