A method and apparatus for a closed end catheter system comprising a catheter body defining a tool lumen sized to receive an elongated tool. The distal end of the tool lumen has a plug therein. A guidewire lumen extends within the catheter body and is sized to receive a guidewire. The guidewire lumen extends along at least a portion of the length of the tool lumen such that the tool lumen and the guidewire lumen are in a biaxial relationship. The elongated tool has a distal tip and a working portion near the distal tip. Two marker bands are affixed to the catheter body and are separated from each other by a distance of not less than the length of the working portion of the tool. The elongated tool extends longitudially through the tool lumen such that when the distal end of the tool rests against the plug, the working portion of the tool is located between the first and second marker bands.
