Abstract
An improved catheter assembly and method are provided for delivering guide wires to vessels. The catheter assembly of the present invention has the feature of containing two guide wire lumens in a single catheter to prevent wire wrapping and crossing of the wires. A torquing member is provided to assist in rotation of the catheter. The assembly allows for the delivery of a wire into a side branch vessel that is at a steep angle with respect to a main vessel. The assembly also provides for the delivery of two guide wires to a bifurcation.
