A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis, and proximal and distal end portions spaced apart from one another along the axis. The elongate body is sized and shaped to be received in the body lumen. A tissue-removing element is mounted on the 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 defines a guidewire lumen. The inner liner is coupled to the tissue-removing element at a distal end portion of the inner liner. A coupling assembly is disposed in the tissue-removing element for coupling the inner liner to the tissue-removing element. The coupling assembly includes a bushing attached directly to the distal end portion of the inner liner.

Tissue-removing catheter with guidewire isolation liner

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.
