    摘要： A tissue-removing catheter for removing tissue in a body lumen includes an elongate body and a tissue-removing element 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 coupled to a handle at a proximal end of the inner liner. The inner liner defines a guidewire lumen. The inner liner isolates an interior of the guidewire lumen from the elongate body and tissue-removing element such that rotational and torsional forces are not transferred from the elongate body and tissue-removing element to the interior of the guidewire lumen when the elongate body and tissue-removing element are rotated during operation of the tissue-removing catheter.

    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. 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 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. A sensor is arranged with respect to the inner liner and is configured to produce a signal for indicating the presence of a guidewire within the inner liner.

    摘要： A tissue-removing catheter for removing tissue in a body lumen includes a tube extending axially along the catheter. A junction box housing is located at a distal end of the tube. An elongate body extends distally from the junction box housing. The elongate body is sized and shaped to be received in the body lumen. A gear assembly is disposed in the junction box housing. The gear assembly engages the elongate body for rotating 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.
