Study Description
Brief Summary:

The nucleus accumbens (NAcc) has a significant role in the process of opiate addiction and the initiation of relapse after detoxification. There is evidence that deep brain stimulation (DBS) of the NAcc exerts a positive effect on individuals with severe heroin addiction via inhibitory action .

The investigators hypothesise that bilateral stimulation of the NAcc will significantly reduce withdrawal symptoms and thus enable the patients to substantially decrease their Levomethadone usage.

Arms and Interventions

Arm Intervention/treatment
Experimental: Deep brain stimulation Device: Suzhou Sceneray® DBS System
We plan to use the SceneRay 1242 (SceneRay, SuZhou, China) electrode with a diameter of 1.27 mm and 4 contacts. The SceneRay 1242 electrode combined with the SceneRay 1181 implantable pulse generator has the advantage of adaptive coverage area for the Ventral Capsule/Ventral Striatum, enabling simultaneous implantation in the nucleus accumbens (NAc; 2 ventral contacts) and the anterior limb of the internal capsule (ALIC; 2 dorsal contacts) with independently programmed parameters such as frequency, amplitude, and voltage; and remote and wireless programing, which allows for convenient and prompt adjustments in emergency situations. The contact length is 3.0 mm and the spacings between the ventral and dorsal contacts are 2 mm, 4 mm, and 4 mm, respectively, spanning a total length of 22.5 mm (3 + 2 + 3 + 4 + 3 + 4 + 3 mm, with 0.5 mm projecting from the electrode tip).
