Abstract:
1. A delivery system for a self-expanding stent, said system comprises: an inner member located coaxially with an outer member, said inner member and said outer member including a distal and proximal end; a pusher positioned at a proximal end of said inner member; a slider located coaxially with said inner member and positioned to interface with said stent; and a distal stop attached to said inner member, said distal stop including a proximal end and a distal end, wherein before deployment of the stent, said distal end of said distal stop is proximal to the distal end of the stent and the stent is constrained within an inner diameter of said outer member, and during deployment of the stent said slider can rotate about and move longitudinally along said inner member allowing said stent to move distally or rotate within said outer member as said outer member is retracted to deploy said stent and wherein said self expanding stent comprises: a helical strut band helically wound about an axis of said stent, said helical strut band comprising a wave pattern of strut elements, said wave pattern having a plurality of peaks on either side of said wave pattern; and a plurality of coil elements helically wound about an axis of said stent, said coil elements progressing in the same direction as said helical strut band interconnecting at least some of said peaks of a first winding through or near to at least some of said peaks of a second winding of said helical strut band, wherein a geometric relationship triangle is constructed having a first side with a leg length L wherein a coil-strut ratio, is a ratio of said first leg length L
