Stent delivery system

A stent delivery system, the system comprising:

• a) an inner shaft having a length from a proximal end to a distal end;
• b) an outer shaft moveable with respect to the inner shaft, the outer shaft having a proximal end and a distal end;
• c) a stent receiving area on the inner shaft adjacent the inner shaft distal end;
• d) a tip mounted on the inner shaft distal end;
• e) means coupled to the inner shaft and outer shaft for manipulating the outer shaft with respect to the inner shaft;
• f) a stent positioned in the stent receiving area;
• and
• g) a spacer assembly disposed between the inner shaft and the outer shaft, said spacer assembly including a channel spacer, extending coaxially along and in contact with a portion of the length of said inner shaft having a plurality of channels spaced about a circumference of said inner shaft and channel spacer combination, wherein said spacer assembly supports said inner shaft with respect to said outer shaft by eliminating slack when said outer shaft is moved with respect to said inner shaft.
