Abstract
A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis. A handle is mounted to a proximal end portion of the elongate body. A tissue-removing element is mounted on a distal end portion of the elongate body. An inner liner is received within the elongate body and defines a guidewire lumen. An advancer is mounted on the handle and is movable relative to the housing. The inner liner is coupled to the advancer at a proximal end portion of the inner liner such that movement of the advancer causes a corresponding movement of the inner liner to exert a push force on the tissue-removing element to advance the tissue-removing element and a pull force on the tissue-removing element to retract the tissue-removing element for moving the tissue-removing element relative to the handle.
