Each lead design implanted in the globus pallidus interna. Annular DBS lead finite element model (FEM) solution during 2 mA stimulation (a), four contact radially segmented lead (b), four tine splayed lead (c), and eight tine splayed lead (d), and resulting FEM solutions during multicathode stimulation consisting of 0.5 mA at the primary contact and 0.25 mA through the two directly adjacent contacts.
