Abstract

A tissue-removing catheter for removing tissue in a body lumen includes a catheter body assembly having an axis and proximal and distal end portions spaced apart from one another along the axis. At least a portion of the catheter body assembly is sized and shaped to be received in the body lumen. A handle is mounted to the proximal end portion of the catheter body assembly and operable to cause rotation of the catheter body assembly. The handle includes internal handle components that interface with the catheter body assembly. The internal handle components provide at least four interface locations spaced axially along the catheter body assembly. A tissue-removing element is mounted on the distal end portion of the catheter body assembly. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the catheter body assembly within the body lumen.
