Event Description
|
It was reported that a shaft break occurred.The target lesion was located in the carotid artery.An 8x21, 5f, 135cm carotid wallstent® was advanced however, the shaft of the catheter was broken and the stent was dislodged from the delivery system.The catheter was removed and the undeployed stent remained inside the patient.Snaring was not performed as the clear protective sheath was still covering the stent.A non bsc stent was then deployed to trap the detached stent against the vessel wall.No patient complications were reported and the patient's status was fine.

(b)(4).Device evaluated by mfr: the proximal section of a carotid monorail stent delivery system was received for analysis.A break in the outer sheath was identified 168mm distal to the middle outer.The distal section of the break was retained inside the patient and was not received for analysis.Additionally it was noted that the outer sheath was severely kinked and stretched in the region of the break site and several other kinks were found along the length of the device.This type of damage is consistent with the application of excessive force to the delivery system.No other issues were identified during the product analysis.The damage identified during the product analysis is consistent with the application of excessive force.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).
