Abstract
A stent delivery catheter is disclosed. The catheter includes an inner catheter tube and an outer catheter tube which are rotatable relative to each other. The inner catheter and outer catheter include releasable attachment structures to releasably engage the ends of the stent. A proximal hand piece includes controls for enlarging and deploying the stent in a body lumen.

21. A stent delivery device for delivering a stent into a lumen of the body, the stent having a first end and a second end, the delivery device comprising:
-
a main body having a proximal end and a distal end;
an inner tube extending distally from the main body, the inner tube having a distal end releasably connectable to the first end of the stent;
an outer tube extending distally from the main body, the outer tube being rotatably slideable over the inner tube and having a distal end releasably connectable to the second end of the stent;
a sheath extending distally from the main body, the sheath being slideable over the outer tube to at least partially expose the stent; and
a belt extending from the main body and attached to the outer tube, wherein pulling of the belt rotates the outer tube relative to the inner tube. - View Dependent Claims (22, 23, 24, 25, 26, 27)
