Abstract
An apparatus, including an insertion tube having a proximal tube end and a distal tube end that includes an electrode, a first irrigation line including proximal and distal irrigation line ends and configured to supply fluid from the distal irrigation line end through apertures in the tube, and an electrical line including a proximal electrical line end and a distal electric line end coupled to the electrode. The apparatus includes a slip ring unit having a stator, a rotor connected to the proximal electrical line end, and a hollow channel extending through respective centers of the stator and the rotor along a longitudinal axis of the slip ring unit. The apparatus includes a rotary joint in fluid communication with the proximal irrigation line end, an angle sensor configured to detect torsion of the proximal irrigation line end, and a drive mechanism coupled to rotate the rotor responsively to the torsion.
