Abstract
The present technology relates generally to endovascular prostheses. More particularly, the disclosure relates to endovascular prostheses having a graft material and a stent structure attached with a suture, or a seam formed by a suture, where the suture has a coating that expands upon exposure to body fluids. The expansion allows for the coating to fill suture holes in the graft material so as to reduce or eliminate endoleaks.
