Manufacturer Narrative

Manufacturing review: the lot number was not reported.A review of lot records could not be performed.It was therefore not known whether the reported issue was a potential manufacturing related issue.Investigation summary: based on the images provided it was confirmed that two stents had been placed with overlapping technique and that the stent in proximal position was found twisted and fractured.A detailed description of the fracture was not possible due to poor image quality.Potential factors that could have led or contributed to the reported event have been evaluated.Based on the images provided, the evaluation was closed as confirmed for stent twisting.The twisting of this kind of stent is caused by interactions of various use related and anatomical factors with the given stent design.Based on the information available, a definite root cause could not be identified.Labeling review: in reviewing the applicable labeling for this product it was found that the instructions for use (ifu) sufficiently address this potential risk.The ifu closely describes the stent placement by stating: 'confirm that the introducer sheath is secure and will not move during deployment (.) to ensure the most accurate placement, firmly hold the black system stability sheath throughout deployment (.) do not hold the silver stent delivery sheath at any time during deployment.Do not constrict the stent delivery sheath during stent deployment.(.) initiate stent deployment by rotating the thumbwheel in the direction of the arrows while holding the handle in a fixed position.(.) while maintaining a fixed handle position, rotate thumbwheel to obtain initial stent wall apposition of 1cm minimum.(.) with distal end of the stent apposing the vessel wall, deployment continues with the following method (.) while maintaining a fixed handle position, place your finger in front of the deployment slide and slide it from the distal to proximal end.' the ifu also mentions balloon pre and post dilation: 'predilation of the lesion should be performed using standard techniques.' and 'post stent expansion with a pta catheter is recommended.' (b)(4).
