Abstract
This disclosure sets out a catheter for bodily insertion. The catheter tip supports an elongate hollow housing with a window for occlusive material cutting, a cutter head on the interior rotates, driven by a drive wire in the hollow catheter tube. In addition, the cutter head reciprocates or oscillates to cut on its back edge, the edge trimming material entering through the window. The window and optional slots admit the unwanted material and enable trimming for a vacuum removal through the catheter tube. The window is urged into contact by a pair of flexed wires, the wires moving the housing into operative contact.
