摘要:
A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element is an integrally formed, one-piece body and has an annular tissue-removing head at the distal end of a tissue-removing element body. In some embodiments, primary tissue-removing components include an integrally formed cutting tooth and inner shearing member and are spaced angularly around the tissue-removing blade. Secondary tissue-removing components include cutting teeth and are interposed between the primary tissue-removing components around the tissue-removing blade. The tissue-removing element is made by removing material from a blank to form the primary and secondary tissue-removing components.
