A catheter assembly having a sheath, which includes a side wall enclosing
an interior bore, and a distal region. The assembly also has a bendable
catheter tube, which is carried for sliding movement in the interior
bore. A pull wire also runs through the interior bore of the sheath,
preferably within a lumen. The catheter tube has a distal portion with a
coupling which joins the distal portion of the catheter tube and the
distal portion of the pull wire. Relative movement of the pull wire and
the sheath causes bending of the catheter tube outwardly through the
opening, in response to sliding movement of the catheter tube within the
interior bore toward the distal region of the sheath.
