An introducer deploys an endoluminal device in a distal location from a
proximal location. The introducer comprises a retrograde portion, an
anterograde portion axially moveable relative to the retrograde portion,
a shaft having a distal tip and an anterograde sheath attached to the
distal tip, and an inflatable balloon mounted radially outside the
retrograde portion for anchoring the device during deployment from its
proximal end to its distal end. The retrograde portion may comprise
bilumen tubing having an external wall, an internal wall that defines a
central lumen radially inward of the internal wall, and an annular lumen
in fluid communication with the balloon defined between the external wall
and the internal wall.
