Abstract

Devices for removing implanted objects from body vessels are provided. A device includes a sheath assembly having a cutting tip. The cutting tip includes a cutting surface that is adapted to cut tissue coupled to an implanted object as the cutting tip rotates. The sheath assembly further includes an outer shield carried outside of the cutting tip. The outer shield includes a distal opening, and the outer shield is translatable relative to the cutting tip from a first position to a second position and vice versa. In the first position the cutting surface of the cutting tip is disposed within the outer shield, and in the second position the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield.
