ABSTRACT:
An over-the-wire catheter includes an elongated shaft having a guidewire lumen extending substantially the entire length of the catheter for receiving a guidewire. The catheter has a length relative to the guidewire such that the guidewire can simultaneously extend out the proximal and distal ends of the catheter. The catheter shaft includes a window opening the guidewire lumen to the exterior of the catheter. The window is of such a length and is so located on the shaft that as the catheter is withdrawn proximally over the guidewire, the window is exposed to provide access to the guidewire before the proximal end of the guidewire is disposed distal to the proximal end of the catheter and such that the distal end of the catheter is exposed to provide access to the guidewire extending therefrom before the proximal end of the guidewire is disposed distal to the window.
