Abstract
A stent delivery system for delivering a plurality of stent segments to at least one treatment site includes a catheter shaft having a proximal end and a distal end, a plurality of expandable members arranged axially along the catheter shaft near the distal end, a plurality of stent segments, and a selecting mechanism adapted for selecting one or more expandable members for expansion. Each expandable member is expandable independently of at least one other expandable member, and each expandable member has at least one stent segment positioned on it. One or more of the expandable members may be selectively expanded to deploy the one or more stent segments positioned thereon at the treatment site.

36. A method for delivering a plurality of stent segments to at least one treatment site, the method comprising:
-
positioning a distal portion of a stent delivery catheter device at a first treatment site, the stent delivery catheter having a plurality of expandable members positioned thereto, each of the expandable members having one or more stent segments positioned thereon;
selecting one or more first expandable members for expansion; and
expanding only the one or more first expandable members to deploy at least a first stent segment at the first treatment site, while at least a second expandable member and at least a second stent segment on the stent delivery catheter remain unexpanded. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
