Device is combination product.(b)(4).The eluvia self-expanding stent delivery system was returned with a.014 guidewire inside the device.The outer shaft, mid-shaft, proximal liner and the remainder of the device were checked for damage.The handle was previously opened when received.Visual examination showed that the outer sheath showed no damage.The mid-shaft showed no damage.The pull rack showed damage on the 1st tooth.The thumbwheel showed minor damage.The stent was not returned.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The investigation conclusion is caused by other device as another device/drug/subsequent procedure caused the complaint event.The eluvia dfu states that a stiff 0.035 in guidewire is strongly recommended for deployment of the stent, especially for tortuous anatomy and contralateral approaches.Use of undersized guidewires may lead to insufficient support of the device which can compromise stent delivery (b)(4).
