Abstract
An intravascular catheter has an outer end portion formed with a discharge orifice. A flexible centering wire supports the outer end portion of the catheter within a blood vessel while a treating agent is delivered into the blood vessel through the discharge orifice. The centering wire, in its natural, free state condition, has a coiled distal end portion. The centering wire is received lengthwise within a channel in the catheter. The centering wire is slidable in the channel from a retracted position to an operative position in which the distal end portion of the wire projects outwardly from the channel through a channel outlet and assumes its natural, coiled condition in contact with the interior wall of the blood vessel to support the outer end portion of the catheter within the blood vessel. The outer end portion of the catheter is centered within the blood vessel, out of contact with the interior wall of the blood vessel.
