Abstract
The present disclosure provides a tissue-removing catheter for removing tissue in a body lumen that includes an elongate body, a handle, tissue-removing element, liner assembly, and coupling assembly. The elongate body is sized and shaped to be received in the body lumen. The tissue-removing element is mounted on a distal end portion of the elongate body and removes tissue as rotated by the elongate body. The liner assembly defines a guidewire lumen. The coupling assembly is coupled to the liner assembly with a first orientation and a second orientation relative to the coupling assembly. The first orientation permits distal movement of the liner assembly relative to the coupling assembly prior to rotation of the elongate body to rotate the tissue-removing element. The second orientation is relative to the coupling assembly after rotation of the elongate body to prevent distal movement of the liner assembly relative to the coupling assembly.
