Abstract
A vascular catheter comprises a catheter body having a fixed guide wire secured to its distal end. The fixed guide wire includes an axial passage which is aligned with a wire lumen within the catheter body so that the vascular catheter can be introduced to the vascular system over a movable guide wire. The catheter body typically comprises flexible tube having a housing secured to its distal end. A variety of interventional devices, including both therapeutic and diagnostic devices, can be disposed within the housing. Use of both a fixed guide wire and a movable guide wire facilitates initial introduction of even large diameter vascular catheters, while allowing subsequent repositioning of the catheters after the movable guide wire has been withdrawn.
