    Abstract: An intraluminal catheter comprising an elongated shaft having a proximal end, a distal end, at least one lumen, and a distal tip having an internal taper. The distal tip has an inner surface tapering distally to an inner diameter smaller than an inner diameter of the shaft proximal to the tapered distal tip. In one embodiment, the distal tip includes an outer surface tapering distally to an outer diameter smaller than an outer diameter of the shaft proximal to the tapered distal tip. In a presently preferred embodiment, the distal tip defines at least in part a guidewire receiving lumen.
