Claim:
1. A catheter device for positioning a guidewire across an occluded portion of a vessel, the device comprising: an elongate catheter body having a distal region comprising a metal band extending longitudinally along a wall of the elongate catheter body, wherein the distal region has a pre-biased configuration and is configured to be bent to a fixed angle along the metal band; an integrated rotatable distal tip comprising one or more channeled flutes extending around the distal tip, the rotatable distal tip configured to be rotated in a first direction to dissect tissue and a second direction for bluntly contacting tissue, wherein the rotatable distal tip comprises a slip collar that engages a slip ring fixedly coupled to a distal end of the elongate catheter body to hold an axial position of the integrated distal tip fixed relative to the distal end of the elongate catheter body while allowing rotation relative to the elongate catheter body; a proximal handle region including a control for rotating the distal tip in either the first or second directions; and a catheter lumen extending through the elongate catheter body, the catheter lumen configured to pass a guidewire.
