Stimulation Guidelines
Charge Density
The Clinician Programmer (CP) software provides a warning when the charge density at
a contact is about to be programmed to exceed 30 µC/cm
is evidence of tissue damage above this level. However, the CP allows the stimulation to
continue above this level.
This graph displays the recommended maximum charge density of 30 µC/cm
different combinations of current amplitude (mA) and pulse width (µs). 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. Do not set the default amplitude outside of the
minimum and maximum amplitude range.
Note: A warning will pop-up on the Clinician Programmer screen if the stimulation
parameters will cause the charge density to exceed 30 µC/cm
per stimulation phase, as there
