摘要：
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 handle is mounted to the proximal end portion of the elongate body and operable to cause rotation of the elongate body. A tissue-removing element is mounted on the distal end portion of the elongate body. An inner liner is received within the elongate body and coupled to the handle at a proximal end of the inner liner. A sensor is arranged with respect to the elongate body and inner liner and is configured to detect wear of the inner liner caused by the elongate body contacting the inner liner during use.
