Figure 15 displays the recommended maximum charge density for different combinations of Amplitude (mA) and Pulse Width (μs). The solid black line (Limit: 6 mm
refers to all Contacts on DB2201‑Standard Lead and the proximal and distal Contacts of DB2202‑Directional Lead. The dashed black line (Limit: 1.5 mm
the small directional contacts of DB2202‑Directional Lead. These estimates of charge density are only for the Boston Scientific DBS Leads.
WARNING:
Patients may have the ability to change the Amplitude with the Remote Control. The physician should set and verify the maximum and
minimum Amplitude levels allowed by the Remote Control to ensure that current levels remain safe.
Energy Use Index
The Energy Use Index applies to non‑rechargeable Stimulators only. The Energy Use Index gives you an estimate of longevity of the battery life on the Program
selected. After the optimal settings have been identified for a Program, from the Program Tab, select Program Options and then select Battery to obtain the Energy
Use Index.
Use Figure 16 to identify the longevity that corresponds to this Energy Use Index. The figure takes into account nominal non‑therapy power consumption, including
shelf‑life and patient remote control use. If the estimate for longevity obtained is below 12 months, consider evaluating a Boston Scientific rechargeable system.
