Selecting Contacts - Boston Scientific Vercise DBS Mode D'emploi

Selecting Contacts

You may program the patient either by manually selecting anodes and cathodes in Custom Mode
or automatically trolling the stimulation field along the lead in E-Troll Mode. Both monopolar and
multipolar configurations are permitted in Custom Mode.
A monopolar configuration uses only cathode(s) on the contacts, with the stimulator case acting as
the anode. A multipolar configuration has anode(s) and cathode(s) assigned to the contacts.
Note: Prior to measuring impedances for the first time, all contacts will display an "X" After
an impedance measurement, only contacts with an Impedance over 4500 Ω will
display an "X". Impedances over 4500 Ω are considered to be resultant from open
or unconnected wires. Although an "X" inside a contact indicates higher than normal
impedances, contacts may still be included in a stimulation configuration.
E-Troll Mode
E-Troll Mode is an enhanced way of conducting a monopolar review. E-Trolling allows you to
steer a monopolar cathode along the selected Lead with a single button – eliminating the need to
manually select each contact. E-Troll gradually shifts a percentage of the monopolar cathode to the
next contact using current steering technology to create smooth transitions between contacts.
To E-Troll along a lead:
1
Switch to E-Troll mode by clicking
2
Select a contact to assign it as a cathode and adjust the amplitude.
3
Use the
stimulation focus.
To choose another starting point or to E-Troll on the other lead, click another contact.
Note: The amplitude for the selected Area will drop to 0.1 mA when another contact
is selected.
Note: Contacts assigned in a multipolar configuration in one Area cannot be assigned to a
monopolar configuration in another Area, so E-Trolling is interrupted in such cases.
