ABSTRACT:
A method and apparatus facilitate movement of a catheter through a blood vessel in a direction substantially parallel to the longitudinal extent of the catheter, by mechanically oscillating the catheter to impart movement at least to the distal end of the catheter in a direction substantially transversely to the longitudinal extent of the catheter. The oscillatory movement transverse to the longitudinal extent of the catheter continuously repels the catheter from the walls of the vessel in which the catheter is disposed, thereby reducing friction between the catheter and the blood vessel and making movement of the catheter within the vessel easier for implantation and explantation of the catheter.
