ABSTRACT:
A guide wire for assisting in implantation and balancing of an orbital atherectomy device is disclosed. The guide wire is generally configured to be received within a driveshaft and cutting region of the orbital atherectomy device. The guide wire is sufficiently flexible to minimize trauma to the vessel walls is positioned within a patient. The distal end of the guide wire can include on or more weighted elements movable along the distal region of the guide wire to permit the balancing of an a rotating drive shaft and cutting region of an orbital atherectomy device. The guide wire can also include an atraumatic tip located on the end of the guide wire to reduce trauma to the vessels during implantation. Lubricious coatings are also provided to reduce friction between the driveshaft and cutting region of the atherectomy device and guide wire.
