Product history review: a review of the manufacturing records indicated the lot met all pre-release specifications.Explant investigation (ei): the following is a summary of the ei observations for the gore-tex® vascular graft (vgf).Tissue present: yes.The fragments were generally devoid of tissue, except for a few variably sized, scattered plaques of brown, dark brown, and yellow tissue present on the abluminal surfaces.The lumens were not patent.Vgf-1: extremity a was transected and ligated with a blue suture.In addition, the rings were absent in the area of extremity a (approximately 10 mm in length).Extremity b was transected.A disrupted ring was present near extremity a.Vgf-2: the fragment presented in a j-shape with rings absent in an area of the fragment near extremity a.The area absent of rings presented in a bent and partially flattened manner with a transverse transection present.Tan tissue was observable inside of the transverse transection.Evenly spaced serration marks were present on the abluminal surface near extremity b, which presented in a flattened/pinched manner with ring disruption present.Material disruptions (i.E., transections, suture ligature, absent/broken rings, device flattening/pinching, serration marks) are consistent with those caused by surgical instrumentation manipulation (i.E., scalpel, scissors, suturing, forceps, clamps) during a surgical procedure.Request for additional analysis: no.Reason: based on the ei¿s review of the third party report and reason for explant (infection), no additional analysis is requested.It was reported to gore that the thigh amputation is not attributable to our gore device.
