Abstract
A tissue-removing catheter for removing tissue in a body lumen includes an elongate body sized and shaped to be received in the body lumen. A handle is mounted at a proximal end portion of the catheter and is operable to cause rotation of 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. A guidewire lumen extends through the elongate body from a distal end of the catheter to an intermediate location on the catheter spaced distally from the proximal end portion of the catheter. The guidewire lumen is configured to receive a guidewire such the catheter can be removed from the body lumen by pulling the catheter along the guidewire without removing the guidewire from the body lumen.
