A catheter having improved ability to cross body passage obstructions and that more easily allows backloading of a guidewire into the lumen of the catheter is comprised of a tip, a shaft, and a lumen. The distal end of the catheter tip is oriented at an angle other than 90° to the lengthwise axis of the catheter tip. A guidewire may be easily backloaded into the elongated catheter lumen at the location of the angled catheter tip.
