Event Text Entries

[75835919] Stent returned to numed completely mangled the covering was not returned. Further analysis is not possible due to the condition of the stent and the absence of the covering. The detachment of the covering is confirmed. This was the physician's first time using this device unaided, so it is likely that inexperience played a role in the failure. The report states that the physician used " 16 and 18" f hemostasis tools to insert the stent in to a 12f introducer. Numed only provides 12, 14 and 16f hemostasis tools with unmounted stents. If a 16f hemostasis tool was used with a 12f introducer, the distal end of the hemostasis tool would have collapsed, making it difficult to advance the stent. The use of umbilical tape to crimp the stent may have also contributed to the failure. Numed recommends crimping the stent by hand. Crimping instructions are included in the instructions for use and there is an instructional video on numed's website. A sample from this lot was tested for covering strength. The covering failed at 2. 54 lbf, which is above the 1. 5 lbf minimum. This complaint was for (2) covered cp stents. The other stent will be reported through mdr # 1318694-2017-00012.
