Abstract:
1. An endoluminal prosthetic device, comprising: a graft comprising a bio-compatible material and at least one lumen extending longitudinally therein; a first stent comprising a plurality of struts and apices between the struts, wherein at least one apex in the first stent is secured to the graft by looping a thread around and at the apex and through the graft material forming a first knotted stitch, and wherein the first knotted stitch prevents the at least one apex in the first stent from moving relative to the graft; and a second stent comprising a plurality of struts and apices between the struts, wherein at least one apex in the second stent is secured to the graft by looping the thread around and at the apex and through the graft material forming a second knotted stitch, wherein the second knotted stitch is formed by the same thread forming the first knotted stitch, and wherein the second knotted stitch prevents the at least one apex in the second stent from moving relative to the graft, wherein the thread forms a running suture linking the first knotted stitch of the first stent and the second knotted stitch of the second stent, wherein the running suture extends at least partially in a longitudinal direction from the first knotted stitch to the second knotted stitch; and wherein the running suture strengthens the endoluminal prosthetic device by adding strength to bonds between the first stent, the second stent, and the graft.
