Title: TISSUE-REMOVING CATHETER
Abstract:
A tissue-removing catheter (10) for removing tissue in a body lumen includes an elongate body (12) sized and shaped to be received in the body lumen. A handle (40) is mounted at a proximal end portion of the catheter (10) and is operable to cause rotation of the elongate body (12). A tissue-removing element (20) is mounted on a distal end portion of the elongate body (12). The tissue-removing element (20) is configured to remove the tissue as the tissue-removing element (20) is rotated by the elongate body (12) within the body lumen. A guidewire lumen (24) extends through the elongate body (12) from a distal end of the catheter (10) to an intermediate location on the catheter (10) spaced distally from the proximal end portion of the catheter (10). The guidewire lumen is configured to receive a guidewire (26) such the catheter (10) can be removed from the body lumen by pulling the catheter (10) along the guidewire (26) without removing the guidewire (26) from the body lumen.
