Abstract
A catheter for positioning a guidewire across an occluded portion of a vessel includes an elongate catheter body, an integrated rotatable distal tip, a proximal handle region, and a catheter lumen extending through the elongate catheter body. The elongate body has a distal region configured to be bent to a set angle. The integrated rotatable distal tip includes one or more channeled flutes extending around the distal tip that are configured to be rotated in a first direction to dissect tissue and a second direction for bluntly contacting tissue. A proximal handle region includes a control for rotating the distal tip in either the first or second directions. The catheter lumen is configured to pass a guidewire.
