Figure 1: The proposed stereotaxic system for implanting a curved lead to human/primates.
From: The “curved lead pathway” method to enable a single lead to reach any two intracranial targets

(a) The frame, including the bottom frame, supporting poles and skull screws. (b) The adaptor (black arrow) and vertical plank (black dovetail arrow) are added to the frame in figure a. (c) The horizontal plank (black triangle) and positioning pole (black dovetail arrow head) are added to the system in figure b. (d) The positioning poles (hollow arrow) are added to the system in figure c. (e) Positioning sheath (hollow triangle) is added to the system in figure d. (f) Trocar within the guiding sheath (hollow dovetail arrow) is added to the system in figure e. (g) From left to right: positioning sheath, positioning sheath with the guiding sheath passes through, and the trocar inserted in the guiding sheath. (h) From top to bottom: positioning base and the deflection angle measurement device.
