WebFeb 8, 2024 · In-vivo patency of NanoGrafts was 100% at 2- and 4-weeks, with no changes over time in lumen size, flow velocities, and minimal foreign-body inflammatory reaction. However, the patency of ePTFE at 2-week was 66% and showed marked infiltration, neointimal thickening, and poor host tissue integration. WebePTFE grafts exhibit certain in vivo behaviors that are important for their use as graft materials. For example, an abdominal wall hernia is a protrusion of the intestine through an opening or area of weakness in the abdominal wall. Treatment involves surgery to repair the hernia using a patch [13].
