Benefits of technology

The technology described in this patented system allows an implanted medical device called Deep Brain Stimulator (DBS) that has been trained on patients' brains to treat neurologically related conditions like substance abuse or anxiety attacks without causing harmful side effects from traditional methods. This helps improve therapy efficacy while minimizing negative outcomes associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding effective ways to treat substance abusing behaviors such as overeating or alcoholism with medication like methadone (methamphet) due to their negative impact on individuals who take them outdoors without being able to stop drinking from these products themselves.

[0048] The distance P1 between the output electrode contacts 810 and 820 in the first group of output electrode contacts is 0.5 mm.

[0049] The distance P2 between the first group of output electrode contacts and the second group of output electrode contacts is 3.5 mm.

[0050] The distance P3 between the output electrode contacts 930 and 940 in the second group of output electrode contacts is 0.5 mm.

[0051] The lengths L1, L2, L3, and L4 of the electrode contacts 810, 820, 930, and 940 are all 0.5 mm.

Embodiment 2

[0053] The distance P1 between adjacent electrode contacts 810 and 820 in the electrode contact group of the first intracerebral functional area is 2mm.

[0054] The distance P2 between the electrode contact group of the first functional area of ​​the brain and the electrode contact group of the second functional area of ​​the brain is 4 mm.

[0055] The distance P3 between the output electrode contacts 930 and 940 in the second set of output electrode contacts is 4mm.

Embodiment 3

[0058] Typical case: male, 38 years old, married, height 180cm, weight 60kg. Repeated use of heroin for 16 years, in the form of scalding and smoking, with a dose of 0.5g / day. There is a sense of euphoria when using it, and discomfort symptoms such as irritability, tearing, yawning, muscle aches, insomnia, etc. after withdrawal, and a strong sense of psychological desire. He has had compulsory withdrawal and self-abstinence for 10 times, and the longest withdrawal time is 18 months (working in other places, when he is about to arrive at his hometown by train, he will have a strong psychological desire, and he will recover on the day he returns to his hometown. Suck). When living locally, the longest withdrawal time is 6 months. During the period of drug use, he can maintain his work intermittently (in order to raise drug funds), only interested in drug use, and indifferent to other things. Although married, the frequency of sexual life between husband and wife is low, about...

Abstract

The invention discloses a deep brain stimulation electrode. The deep brain stimulation electrode comprises at least two groups of output electrode contacts; one or more output electrode contacts are arranged in each group of the output electrode contacts; one or more output electrode contacts of the first group of the output electrode contacts are arranged at the brain nucleus accumbens septi part after the output electrode contacts are mounted; one or more output electrode contacts of the second group of output electrode contacts are arranged at the brain internal capsule anterior limb part after the output electrode contacts are mounted. The invention further discloses a deep brain stimulation device provided with the electrode, and a deep brain stimulation method used for drug rehabilitation. According to the invention, simultaneous combined stimulation to the nucleus accumbens septi and the internal capsule anterior limb difunctional areas is realized by one electrode; specific stimulation can be conducted on different brain functional areas; the availability and safety of the deep brain electric stimulation on abstinence of drugs, and treatment of psychogenic illnesses of obsessive-compulsive disorder, depressive disorder, and the like are improved.
