Abstract: A method for treating a body vessel using a stent formed from filaments of titanium or titanium alloys such as Ti—13Zr—13Nb.

Abstract: A stent delivery device having a pair of balloons at a proximal end of a catheter and having separate lumens for selectively inflating the respective balloons. The outer balloon is relatively compliant and the inner balloon is relatively non-compliant. A central lumen is provided for a guide wire. A stent is carried by the delivery device within an axially retractable sheath at the distal end of the catheter and is deployed by retraction of the sheath and inflation of the compliant balloon, and the stent is subsequently expanded by inflation of the non-compliant balloon.
