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.
A flexible elongate device for crossing a stenosis of a totally or almost totally occluded vessel of a patient, comprising a flexible elongate tubular member having proximal and distal extremities, a rounded tip, electrically actuatable means carried by the distal extremity of the flexible elongate tubular member, means for connecting the electrically actuatable means to the rounded tip and means for supplying electrical energy from the proximal extremity of the flexible elongate tubular member to the electrically actuatable means at the distal extremity of the flexible elongate tubular member for imparting vibratory impact motion to the rounded tip for facilitating advancement of the rounded tip through the stenosis.
A method for crossing a stenosis of a totally or almost totally occluded vessel of a patient by the use of a flexible elongate device having proximal and distal extremities, a rounded tip and electrically actuatable means carried by the distal extremity and connected to the rounded tip for imparting vibratory motion to the rounded tip, comprising advancing the rounded tip of the device in the vessel into contact with the stenosis and supplying electrical energy from the proximal extremity to the electrically actuatable means at the distal extremity thus generating vibratory motion at the distal extremity which imparts vibratory impact motion to the rounded tip to facilitate advancement of the rounded tip through the stenosis thereby forming a passage through the stenosis without danger of penetrating the wall of the vessel.
