4 4 AN END-ANGLE-CONTROLLED CATHETER DEVICE USING FOUR GUIDE LINES IN FOUR DIRECTIONS OF UP AND DOWN AND LEFT AND RIGHT DIRECTIONS AND A METHOD OF USING THE SAME
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a catheter apparatus for adjusting an end angle using four guide lines in four directions of upper, lower, left, and right directions, and more specifically, a catheter apparatus having an elongated flexible tube, Four wires arranged at intervals of 90 [deg.] Apart, one end being guided to the distal end of the catheter body, one end of the four guidewires being spaced at 90 [deg.] From the distal end of the catheter body And four inlet holes which are arranged at a position shifted by a predetermined distance in the direction of the catheter body from the fixed portion at the distal end of the catheter body to draw the four guide lines into the inside of the catheter body By adjusting the lengths of the four guide lines drawn to the distal end of the catheter body, And to control a feature of the configuration thereof. The present invention also relates to a method of using an end angle-adjustable catheter apparatus using four guide lines in four directions of upper, lower, left, and right directions, more specifically, as a tube having flexibility of elongated shape, , Four wires arranged at intervals of 90 [deg.] From each other, one end of the four lead wires arranged at 90 [deg.] Apart from each other at the distal end of the catheter body to which the other end is led to the distal end of the catheter body And four inlet holes for introducing the four guide lines into the interior of the catheter body, which are disposed at a position shifted from the fixed portion at the end of the catheter body by a predetermined distance in the direction of the distal end of the catheter body A method of using a catheter device comprising: (1) a catheter body, which is a flexible elongated tube, And (2) adjusting the distal angle of the catheter body by adjusting the lengths of the four guide lines extended to the distal end of the catheter body. According to the end angle-controll
