the ring of the VarioGuide arm.

General Safety Considerations
Warning
Never loosen the joints while an instrument is inserted into the patient through the
VarioGuide, except for joint 1, in order to swing the arm away from a placed catheter or
similar.
Warning
Do not grip the VarioGuide around the ball joints while the arm is moved as you could
injure your hands or fingers.
Warning
To maintain adequate friction, do not lubricate the joints.
