Title: TISSUE-REMOVING CATHETER WITH GUIDEWIRE ISOLATION LINER
Abstract:
A tissue-removing catheter (10) for removing tissue in a body lumen includes an elongate body (12) and a handle (40) mounted to a proximal end portion of the elongate body (12). The handle (40) is operable to cause rotation of the elongate body (12). A tissue-removing element (20) is mounted on a distal end portion of the elongate body (12). The tissue-removing element (20) is configured to remove the tissue as the tissue-removing element (20) is rotated by the elongate body (12) within the body lumen. An inner liner (14) is received within the elongate body (12) and is coupled to the handle (40) at a proximal end portion of the inner liner (14). The inner liner (14) defines a guidewire (26) lumen. The inner liner (14) is coupled to the tissue-removing element (20) at a distal end portion of the inner liner (14) such that translational movement of the inner liner (14) in the body lumen causes a corresponding translational movement of the tissue-removing element (20).
