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.
