A surgical device for minimally invasive implantation of experimental deep brain stimulation leads in large research animals.
Deep brain stimulation (DBS) in experimental animals has promoted new indications and refined existing treatments. Implantation of downscaled clinical DBS leads directly compatible with commercially available implantable pulse generators can however be challenging. Accordingly, we have developed a lead implantation device (LID) and technique for minimally invasive implantation of experimental multicontact DBS leads in large research animals. ⋯ The LID was easy to handle and capable of accurate stereotaxic implantation of downscaled experimental DBS leads in the predetermined target brain structures with minimal surrounding tissue reaction. The device may benefit future large animal DBS research as it allows for precise implantation of DBS leads and may have implications for further refinement of clinical DBS leads.
