Abstract
A stent delivery system is disclosed that has an outer assembly and an inner assembly that accommodates a stent. The inner assembly further has an external assembly contact area projecting from its surface that frictionally contacts an inner surface of the outer assembly. The contact area is positioned at one end of the inner assembly, proximal to the stent accommodating area. Also disclosed is a method of using the stent delivery system.

47. 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 an outer lumen, and an outer surface;
an inner elongated structure having a proximal end, a distal end, and an inner surface defining an inner lumen, the inner elongated structure being disposed inside the outer lumen; and
a plurality of contact areas projecting from the inner elongated structure and arranged sequentially along a length of the inner elongate structure, at least one of the plurality of contact areas being longer than the stent, wherein the plurality of contact areas increase in flexibility from the proximal end of the inner elongated structure to the distal end of the inner elongated structure. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)

65. A system for delivering a stent into an anatomical structure, the system comprising:
-
an outer tubular structure having a proximal end, a distal end, and an inner surface defining a lumen, wherein the outer tubular structure has a translucent region at the distal end, the translucent region having a length less than a length of the stent;
an inner elongated structure having a proximal end and a distal end, the inner elongated structure being located within 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
a contact area projecting from 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, wherein the translucent region is coextensive with at least a portion of the stent accommodating area, wherein the outer tubular structure has a substantially constant diameter between the proximal end and the distal end. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73, 74)
