Patent ID: 7011675

Claim:
A system for delivering a stent into an anatomical structure, the system comprising: an outer tubular structure having a proximal end, a distal end, an inner surface defining a lumen, and an outer surface, wherein the outer tubular structure has a translucent region at the distal end and the translucent region has a length less than a constrained length of a stent placed within the outer tubular structure, wherein the outer tubular structure is devoid of braiding along the length of the translucent region between the inner and outer surfaces; an inner elongated structure having a proximal end and a distal end, the inner elongated structure being located within the outer tubular structure such that the distal end of the inner elongated structure substantially coincides with the distal end of the outer tubular structure; a stent accommodating area on the distal end of the inner elongated structure, the stent accommodating area accommodating the stent; and an external tubular structure contact area projecting from a surface of the inner elongated structure and located closer to a proximal end of the stent accommodating area than a distal end of the stent accommodating area, the external tubular structure contact area frictionally sliding against an interior surface of the outer tubular structure, wherein the translucent region is coextensive with at least a portion of the stent accommodating area.
