Abstract
A catheter device for crossing occlusions includes an elongate catheter shaft, a rotatable tip configured to rotate relative to the elongate catheter shaft, a drive shaft, and an OCT imaging sensor. The rotatable tip includes a central guidewire lumen, a distal grinding surface, and a fluted portion. The distal grinding surface can be substantially perpendicular to the guidewire lumen and include divots and sharp points that form pyramidal features, where the sharp points extend distally from the distal grinding surface. The fluted portion can have flutes extending around a circumference of the rotatable tip proximal to the distal grinding surface. The fluted portion may not include the divots and sharp points that form the pyramidal features of the distal grinding surface.
