Synopsis

Keywords: Safety, Safety

When implanting a DBS system, the excess amount of extension wires is looped and placed in different regions (near the skull burr holes or in the chest), depending on the neurosurgeon/institution. In this study, we tested three different DBS configurations with excess extension wires looped behind the IPG. A phantom with a DBS device (lead model B33005, IPG Percept B35200, and Extension wire model B34000) was used to perform this study. We observed that the temperature rise was higher with one loop placed behind the IPG compared to two or no loops.
