ABSTRACT:
A flexible elongate device including a flexible elongate tubular member having proximal and distal extremities. A flexible coil spring is provided having proximal and distal extremities. The proximal extremity of the coil spring is secured to the distal extremity of the flexible elongate tubular member. A rounded tip is secured to the distal extremity of the coil spring. A flexible elongate element having proximal and distal extremities is disposed within said coil spring and extends longitudinally of the coil spring. The distal extremity of the flexible elongate element is secured to the rounded tip. A vibrator is secured to the proximal extremity of the flexible elongate element for imparting vibratory motion to the flexible elongate element to cause vibratory impact motion of the rounded tip in a direction longitudinal of the axis of the flexible elongate element.
