ABSTRACT:
Elongate flexible elements are guided into place within a tortuous body passage by providing the elements with annular guides adjacent their distal ends and sliding the elements over a guide wire extended through the passage. Column strength to move the elements through the body passage may be provided by a tubular pusher slidably received on the guide wire. The annular guides are localized at the distal ends of the members so that a plurality of members may be sequentially or simultaneously guided into place over a single guide wire.
