Evaluating the Longevity of Implantable Pulse Generator Used in Deep Brain Stimulation: A Systematic Review

Background and Aim: Deep Brain Stimulation (DBS) surgery is increasingly performed to treat movement disorders. In these patients, a rechargeable or non-rechargeable battery is placed under their subcutaneous chest after implantation of an electrode in the basal ganglia of the brain, which has different battery life. Methods and Materials/Patients: In this study, three databases, including PubMed, ScienceDirect, Scopus without time limit, and Google Scholar search engine were examined by two independent researchers. Results: In the initial search, a total of 338 data were found. Then, by reviewing the title and summary of articles, 17 articles were included in the study and then 13 articles were reviewed in full text. The results of the articles were divided into two subgroups of battery life related to the types or subtypes of movement disorders indicated by DBS and battery life related to the types of IPG models. Conclusion: Battery life in Parkinson’s movement disorder and tremor is longer than in dystonia. Also, the battery life of Soletra model is longer than Kinetra and Kinetra model is longer than Activa, and any battery replacement surgery reduces battery life.
