Abstract
An atherectomy catheter for performing an atherectomy procedure, the atherectomy catheter includes a catheter body defining one or more lumens, a core wire extending through a core wire lumen of the one or more lumens of the catheter body, and an abrasive bead slidably mounted to the core wire. The core wire is configured to be coupled to an excitation device and operation of the excitation device causes the abrasive bead to rotate about and slide longitudinally along the core wire.
Claims20
An atherectomy catheter for performing an atherectomy procedure, the atherectomy catheter comprising:
- a catheter body defining one or more lumens;
- a core wire extending through a core wire lumen of the one or more lumens of the catheter body;
- and
- an abrasive bead slidably mounted to the core wire,
- wherein the core wire is configured to be coupled to an excitation device and operation of the excitation device causes the abrasive bead to rotate about and slide longitudinally along the core wire.
An atherectomy assembly for performing an atherectomy procedure, the atherectomy assembly comprising:
- a catheter body defining one or more lumens;
- a core wire extending through a core wire lumen of the one or more lumens of the catheter body;
- an abrasive bead slidably mounted to the core wire, and
- an excitation device operatively coupled to the core wire and configured to vibrate the core wire,
- wherein vibration of the core wire causes the abrasive bead to rotate about and slide longitudinally along the core wire.
A method of operating an atherectomy device, the method comprising:
- providing the atherectomy device that comprises:
- a catheter body defining one or more lumens;
- a core wire extending through a core wire lumen of the one or more lumens of the catheter body;
- and
- an abrasive bead slidably mounted to the core wire;
- and
- activating an excitation device operatively coupled to the core wire to provide a vibration to the core wire, causing the abrasive bead to rotate about and slide longitudinally along the core wire.
