Patent ID: 10925713

Abstract:
The disclosure is directed to a continuous stitch wire routing and delivery system. The system includes a transitional stitching on a tube of a stent graft. The transitional stitching includes a distal portion stitching and a proximal portion stitching. A portion of each stitch loop of the stitches of the transitional stitching is disposed outside the tube and having a string passing through the stitch loop. A distal portion of the string passes through stitch loops of the distal portion stitching, a middle portion of the string is circumferentially around the tube, and a proximal portion of the string passes through stitch loops of the proximal portion stitching. The stent graft is in a compressed state when a tension of the string is above a high-tension threshold. The stent graft is in an expanded state when the tension is below a low-tension threshold.
