ABSTRACT:
A catheter formed of an elongated shaft with a dilatation balloon at the distal end includes a guide wire lumen external to the balloon. The guidewire lumen extends from the distal tip of the catheter to a proximal port distal from the proximal end of the catheter. The shaft is formed of a proximal hypotube and a distal spring coil. In some embodiments, the wire lumen extends the full length of the catheter and includes apertures for drug delivery or perfusion. A core wire is included to enhance the pushability of the catheter and support the balloon.
