Abstract Details

2009, Master of Sciences (Engineering), Case Western Reserve University, EECS - Electrical Engineering.
This work presents a novel 4-sided, 16-channel deep brain stimulation electrode with a flexible extension lead for connectivity with pulse generation electronics. The 3-dimensional electrode enables steering the current field circumferentially. The electrode is fabricated in pieces by microfabrication techniques; the pieces are then assembled mechanically, after which the lead is connected. The electrode is modeled by finite element analysis and tested in vitro to validate the design concept, i.e., targeted stimulation. With monopolar and bipolar configurations, the electric potential in front of the activated site is at least five times larger than that on the other not-activated sides within a 3 mm radius. The resistance of each channel is also measured. Finally, a pull test is performed to evaluate the mechanical strength of the epoxy used to attach the lead to the electrode. The samples withstood a force of 8.66 g at a 60° angle, thus exhibiting high robustness.
