    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.

    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 turbine is fixed to the elongate body and is disposed at an intermediate position between the proximal and distal end portions of the elongate body. A rotatable tissue-removing element is at the distal end portion of the elongate body and is operatively coupled to the turbine such that the turbine imparts rotation of the tissue-removing element. The tissue-removing element removes the tissue from the body lumen as the tissue-removing element is rotated by the turbine.

    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. 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 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 removal of tissue from the body lumen.

    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 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.
