Abstract
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.
