Abstract
A torquing member is provided in a stent delivery catheter assembly for delivering and implanting a stent at or near a bifurcated vessel. The torquing member, in cooperation with a tracking guide wire and a positioning guide wire, facilitates torquing and rotation of the catheter, and hence the stent mounted thereon, to accurately position and implant the stent at or near the bifurcation.
Claims30
A stent delivery catheter assembly, comprising:
- an elongated catheter having an inflation lumen, a tracking wire lumen, and a positioning 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;
- and
- a torquing member attached to the tracking wire lumen and positioning 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.
