Abstract:
1. An endovascular system for the treatment of aortic dissection in an aorta comprising in combination a deployment device and a stent assembly, the stent assembly comprising a proximal end, a plurality of self expanding zig zag stents and a link arrangement between adjacent stents so that the stents are linked together thereby defining an elongate substantially cylindrical lumen wall engaging surface, each stent having a plurality of struts and bends between the struts and the link arrangement comprising at least one of a biocompatible thread or fiber and knots which are knotted alternately to a bend of one stent and then a bend of an adjacent stent to provide a link thread of zig zag configuration, and the deployment device comprising an elongate catheter to be deployed over a guide wire, a nose cone at the proximal end of the elongate catheter and a trigger wire arrangement to retain the proximal end of the stent assembly just distal of the nose cone, wherein the trigger wire arrangement comprises at least one trigger wire extending through the deployment catheter and the trigger wire engaging with the proximal end of the stent assembly, the proximal end of the stent assembly comprising a proximal stent and the proximal stent comprising proximal bends, a circumferential biocompatible thread extending through the proximal bends and including thread portions between adjacent bends of the proximal end of the proximal stent and the engagement of the trigger wire with the stent assembly comprises the thread portions between adjacent bends extending around the trigger wire.
