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
steer 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.
