摘要：
A tissue-removing catheter for removing tissue in a body lumen includes an elongate body. A tissue-removing element mounted on a distal end portion of the elongate body. The tissue-removing element includes a body including an exterior surface having a first segment extending from a proximal end toward a distal end of the tissue-removing element. A second segment extends from the first segment toward the distal end of the tissue-removing element. A third segment extends from the second segment to the distal end of the tissue-removing element. A transition between the first and second segments defines a first angle formed between the first and second segments. A transition between the second and third segments defines a second angle formed between the second and third segments. 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.
