Manufacturer Narrative

H6: code c19: a review of the manufacturing records for the device verified the lot met all pre-release specifications.The sheath was returned to gore for analysis.The sheath was returned to gore for evaluation.No dilator was returned.As received, the stent could not be withdrawn from the sheath and damage was observed on the leading tip of the sheath.These observations are consistent with the applicable portions of the description summary.Once the stent was removed from the sheath, the evaluation found a 14fr dilator could be advanced and locked in the sheath without issue, therefore the complaint was not confirmed.The inability of the gore® viafort vascular stent to advance out of the sheath could not be determined because the events could not be confirmed.The inability of the gore® viafort vascular stent to be withdrawn was confirmed; however, the root cause could not be determined.This type of occurrence will continue to be monitored.Please note that the gore® viafort vascular stent vns240702c/27311377 used at the procedure is a study device and is not approved for sales in the usa.It was reported that the difficulty to pull the sheath back from the patient was due to the long-standing chronic thrombus.According to the gore® dryseal flex introducer sheath instructions for use (ifu), adequate vessel access is required to introduce the sheath into the vasculature.Careful evaluation of vessel size, anatomy, tortuosity, and disease state (including calcification, plaque, and thrombus) is required to ensure successful sheath introduction and subsequent withdrawal.If vessel is not adequate for access, major bleeding, vessel damage, or serious injury to the patient, including death, may result.Additional considerations for patient selection include but are not limited to patient¿s anatomical suitability for endovascular repair.
