Event Description
|
It was reported that the stent was partially deployed.After pulling the entire system the stent was deployed, however it had stretched.Two 7mm x 120mm, 130cm eluvia drug-eluting vascular stents were selected for use in a stenting procedure in the superficial femoral artery (sfa) as treatment for lower extremity peripheral arterial disease.The vessel was 100 % stenosed and had moderate tortuous severity.During deployment of the additional stent in the proximal sfa, the thumbwheel was stiff and it was difficult to deploy the device.The thumbwheel was turned completely, but the stent could not be deployed by about 4 cm.The guidewire was also stuck in the guide wire lumen, where the remaining part of the stent was deployed by pulling the entire device, but the stent was placed in a slightly stretched state.The delivery system was able to be removed, however there was an observed kink on the shaft at the base of the handle that likely occurred at the time of retrieval.No patient complications were reported.

Manufacturer Narrative
|
Device eval by manufacturer: returned product consisted of an eluvia self-expanding stent system with an unknown 0.014 inch guidewire stuck in the device.The outer sheath, tip, inner sheath and the remainder of the device were inspected for damage.Visual examination revealed that the sheath is kinked at the nosecone.Microscopic and further examination of the reminder of the device revealed no additional damages.The stent was deployed and did not return for analysis.An x-ray of the handle found the proximal inner was prolapsed.The customer used an undersized guidewire during deployment which led to insufficient support and caused the proximal inner to prolapse.Prolapsing of the proximal inner would cause deployment issues, froze on wire, and damage to the stent if the stent did not fully deploy when the device is pulled out.The information suggested that the kink occurred during removal due to complications during the procedure.
