Original lecture slide 19 comparing conventional ring and segmented directional stimulation

DIRECTIONAL DBS

  • Shape the field when anatomy makes every millimetre count
  • CONVENTIONAL RING
  • 360°
  • Omnidirectional field
  • SEGMENTED / DIRECTIONAL
  • Steer current away from
  • sensitive structures
  • Potentially wider therapeutic window — when lead position and anatomy permit.
  • Directional DBS: segmented leads permit current steering; clinical benefit depends on anatomy, lead location and programming.
