Model 3387 dbs lead

Quadripolar electrodes (Model 3387 DBS Lead; Medtronic, Minneapolis, MN, USA) were first implanted bilaterally in the anterior limb of the internal capsule (ALIC) of two subjects (Fig 1(A)), and the nucleus accumbens (NAc) in the following two consecutive cases (Fig 1(B)). Under local anesthesia, placement of electrodes was performed utilizing a stereotactic approach with a Leksell frame. MER utilizing a 5-channel discrete trajectories, the so-called “Ben-Gun”, was conducted to map the region of the brain where the HF-DBS probe was to be placed (Differential microTargeting Electrodes, FHC, Chemnitz, Germany;1.5 MO impedance). After changing to general anesthesia, programmable, battery-operated pulse generators were implanted in both subclavicular fossa, and were connected to the electrodes utilizing a tunneling tool for subcutaneous electrical wires.

Under local or general anesthesia, quadripolar electrodes (Model 3387 DBS Lead; Medtronic; Minneapolis, MN, USA) were stereotactically implanted bilaterally. The two distal contacts (0,1 on the left and 8,9 on the right electrode, respectively) were placed in the NA bilaterally. The more proximal contacts (2,3 and 10,11) were located in the ventral part of the VC. Stereotactic X-ray procedures in the operating room and postoperative CT were used to confirm the correct position of the electrodes postoperatively.

Bilateral quadripolar electrodes (Model 3387 DBS Lead; Medtronic; Minneapolis, MN, USA) were stereotactically implanted bilaterally under local anesthesia. The two distal contacts (0, 1 on the left and 8, 9 on the right electrode, respectively) were placed in the nucleus accumbens within the ventral striatum bilaterally (see Figure 1 for an overview). The more proximal contacts (2, 3 and 10, 11) were located in the ventral part of the VC. Post-operative computer tomography (CT) was used to confirm the correct position of the electrodes post-operatively.
