Abstract

An atherectomy catheter includes a deflectable distal tip, a rotatable cutter proximal to the distal tip, a cutter drive shaft configured to rotate the rotatable cutter, and a pull shaft concentric with the drive shaft and coupled to the distal tip. The pull shaft is configured such that pulling the pull shaft deflects the distal tip, thereby exposing the rotatable cutter. Also disclosed herein is a magnetic drive system configured for non-contact actuation of a catheter.
