1. A stent delivery catheter assembly, comprising:
- an elongated catheter having an inflation lumen, a tracking guide wire lumen, and a positioning guide wire lumen;
an expandable member positioned at a distal end of the catheter and in fluid communication with the inflation lumen;
a stent mounted on the expandable member, the stent being longitudinally flexible and for implanting in a body lumen and expandable from a contracted condition to an expanded condition, the stent having an elongated side aperture for use in treating areas proximate septal perforators without occluding the septal perforators; and
a torquing member attached to the tracking guide wire lumen and positioning guide wire lumen so that as the catheter is positioned in a body lumen, the torquing member assists in properly orienting the stent in the lumen.

Abstract
A stent delivery catheter assembly for delivering and implanting a stent at or near an area of septal perforators includes a torquing member which, in cooperation with a tracking guide wire and a positioning guide wire, facilitates torquing and rotation of the catheter and hence the position of the stent mounted thereon to accurately position and implant the stent at or near the area of septal perforators. The stent of the present invention has an elongated side aperture which is designed to be implanted next to the area of septal perforators to prevent covering of the orifices of the septal perforators.
