Abstract
The bending of the catheter is controlled from the handle by a variable tension exerted to a steering cable housed in an offset longitudinal notch of the catheter. The handle comprises: a body adapted to be held in hand by an operator; a piston, axially mobile in rotation and in translation inside the handle body; a first mechanism with a pulley for the winding of the steering cable and a lever for modifying in a controlled manner the tension of the cable and hence controlling the steering of the catheter; and a second mechanism comprising a member for holding a security wire and a member for adjusting the axial position of this wire with respect to the internal tube of the catheter, so as to keep the security wire in tight condition whatever the bend provided to the catheter by operation of the first mechanism.
