Abstract
A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element includes a cutting edge that extends around the axis of rotation and a depth stop that extends around the axis of rotation radially inward of the cutting edge relative to the axis of rotation. The depth stop defines an engagement surface adapted to engage a hard object and thereby limit the depth at which the cutting edge cuts into the hard object. In use, when the cutting edge cuts into a hard object, the depth stop engages the hard object to limit the cutting depth.
