Physical Characteristics of the Vercise PC Stimulator
Vercise™ PC Implantable Pulse Generator DFU
92104390-01 11 of 15
Physical Characteristics of the Vercise PC
Stimulator
The physical characteristics of the Stimulator are outlined in Table 1. The Stimulator contains a
radiopaque identication tag. The identication tag is visible using standard x-ray procedures.
Table 1: Stimulator Physical Properties
Feature Description
Case Titanium
Header Epoxy
Dimensions 70.9 mm x 49.5 mm x 11.3 mm
Volume 33 cm3
Stimulator Programmable Characteristics
The stimulation parameters are independent for the two DBS Leads such that stimulation of
two different brain targets can have different amplitudes, pulse widths, stimulation rates, and
contact congurations. The two DBS Leads can also have differing monopolar and multipolar
congurations; however, a given DBS Lead contact cannot be programmed as both monopolar and
multipolar. The programmable parameter ranges for the Stimulator are shown in Table 2.
Note: Some frequency combination may not be used. See the Programming Manual for
specic frequency combinations.

A programming interlock is enforced to limit the total output current to 20 mA
or less per coverage area. For example, a maximum current output of 12.7 mA
on one contact would limit the total summed current output on the remaining
contacts to 7.3 mA within one coverage area.
2 The rate is limited to a sum of 255 Hz for a given port. The global rate limit for
each lead is also 255 Hz
