Abstract
A tissue-removing catheter for removing tissue in a body lumen includes an elongate body and a handle mounted to a proximal end portion of the elongate body. The handle is operable to cause rotation of the elongate body. A tissue-removing element is mounted on a distal end portion of the elongate body. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the elongate body within the body lumen. An inner liner is received within the elongate body and is coupled to the handle at a proximal end portion of the inner liner. The inner liner defines a guidewire lumen. The inner liner is coupled to the tissue-removing element at a distal end portion of the inner liner such that translational movement of the inner liner in the body lumen causes a corresponding translational movement of the tissue-removing element.
