(b)(4).Returned product consisted of an eluvia self-expanding stent delivery system (sds) with a.035 guidewire stuck in the device.The outer shaft, mid-shaft, proximal liner and the remainder of the device were checked for damage.Visual examination showed a kink at the nosecone.The guidewire that was stuck in the device was protruding from the distal end approximately 25.5cm from the tip.The wire was protruding from the proximal end approximately 79cm from the handle.The stent was not returned.The handle was opened to inspect for further damage.It was noticed that the mid-shaft was buckled/damaged at the retainer clip.The inner liner was buckled/damaged around the guidewire at the clip area.With the buckled/damaged mid-shaft at the retainer clip around the guidewire and the inner liner buckled/damaged around the guidewire, this most likely contributed to the guide wire being stuck in the device.No damage to the proximal inner was noticed.No damage to the pull rack or the thumbwheel teeth.Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.The most probable root cause is operational context as device performance was limited due to anatomical procedural factors.(b)(4).

It was reported that the delivery system was stuck on the wire.A 6x80x130 eluvia¿ drug-eluting vascular stent system was selected for a percutaneous transluminal angioplasty (pta) procedure.During the procedure, the stent was fully deployed.After deployment, the stent delivery system (sds) could not be removed because it was stuck on the.035 guidewire used.The sds and the guidewire were removed together.There were no patient complications and the procedure had a good outcome.
