1. A delivery system for a self-expanding stent, comprising: an inner member arranged coaxially with the outer member, said inner member and said outer member including a distal and proximal end； a pusher located at a proximal end of said inner member and connected to said inner member； a slider placed coaxially with the specified inner element and located inside and in contact with the inner diameter of the specified stent； a body assembled on a push rod； and a spring element located in the specified housing, and before its placement, the stent is compressed in the inner diameter of the specified outer element, and after partial placement of the stent can be re-compressed by the outer shell and the housing moving in the proximal direction to compress the spring element to hold the inner element with tension , and moreover, during the process of stent placement, the indicated slider can rotate around the indicated internal element and move longitudinally along it, allowing nnomu stent distally move or rotate in said outer member, as said outer member is retracted for placement of said stenta.2. The system of claim 1, wherein said spring element is a compression spring and which further comprises: a pusher stroke limiter, said pusher stroke limiter attached to the proximal end of said pusher and placed in said housing on the proximal end of said compression spring, in order1.
