Directional Leads

The 8 Contact Directional Leads (see Table 17) have rows of Contacts that are segmented
circumferentially to allow both axial and rotational stimulation selectivity. Each segmented Contact
covers 90 degrees of the Lead circumference. Each Directional Lead has a radiopaque marker
whose solid portion aligns with Contact 2. The outer diameter of each Directional Lead is 1.3 mm.
The Directional Leads are compatible with existing commercially available DBS implantation tools.
