(b)(4).Review of device manufacturing record history confirmed device met pre-release specifications.The returned specimen did not include the hub or deployment knob.Part of the device was inside of an introducer sheath, which was not evaluated as it is not a gore product.Approximately 10 cm of dual lumen catheter shaft was coming out of the valve-end of the introducer sheath.The hub end of the dual lumen catheter shaft appeared severed.On the opposite end, there was 9.5 cm of endoprosthesis that was partially expanded.The transition-end of the endoprosthesis appeared to be compressed/constrained within the introducer sheath.The body tape was separated from stent apices at multiple places along endoprosthesis.A loop of deployment line was coming out of the introducer sheath, with part of it looped around struts 7.5 cm from the tip-end of the endoprosthesis.No distal shaft nor distal tip could be visualized outside of the endoprosthesis.Based on the device examination performed, no manufacturing anomalies were identified.

It was reported to gore that a patient presented for treatment in the right superficial femoral artery due to diffused peripheral disease.Pre-dilation was performed with a 3mm diameter balloon.A 6fr sheath was used to advance the gore® viabahn® endoprosthesis across the lesion and placed at the intended treatment site.Deployment was initiated, and about two-thirds of the device expanded when the deployment line broke.The catheter was cut in an attempt to locate the line remaining within the lumen.The line was not located, necessitating removal of the guidewire, sheath and the partially expanded device through the access vessel at the groin.The devices were removed, and an 11fr sheath was inserted.A new viabahn device was advanced and deployed at the treatment site.A cut down was done to repair the artery.Patient was reported to be doing well after the procedure.
