<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for implanting radially expandable prostheses in the body lumens rely on tacking or anchoring of the prostheses with separately introduced fasteners. <P>SOLUTION: This proteose may be self-expanding or balloon expandable. After initial placement, a fastener applier system 27 is introduced within the expanded prosthesis to deploy a plurality of fasteners at at least one prosthesis end, usually as each end of the prosthesis. The fasteners are usually helical fasteners which are delivered from a helical track in the fastener applier by rotation with a rotator wire. The fasteners will be applied singly, typically in circumferentially spaced-apart patterns about the interior of each end of the prosthesis. <P>COPYRIGHT: (C)2009,JPO&INPIT |
