16.1 Conventions
The SAPS operates in a Windows environment with drop-down menus. Standard mouse and
keypad functions are used to navigate through a Windows environment on the laptop.
• The names of selectable buttons (or fields) and drop-down menus appear within the button.
Each of these buttons or fields represents an operation, parameter, or parameter value.
• To select a button or field, move the cursor over the button and select the button using the
mouse or keypad selector.
A glossary and list of symbols is found in the back of this manual (see Section 19: Glossary ).
16.2 Communication Signals
The WT communicates wirelessly bidirectionally through the air and tissue with the IPG at a
distance up to 1 m from the WT by converting USB communications into radio frequency (RF)
communications using a unique, proprietary, and secure protocol that implements the Medical
Implantable Band (MICS, ~403 MHz). This ensures that the IPG is not programmable by other
MICS programmers and that the WT cannot program other MICS based devices.
The communication portion of the Vivistim
®
System is designed to minimize the possibility of mis-
programming or “phantom” programming with the IPG. Phantom programming is the inadvertent
programming via environmental sources of electromagnetic interference (EMI). All IPG
parameters are programmed and verified during each programming event.
16.3 Wireless Transmitter
The WT (see Figure 16.1) is the bi-directional RF communication link between SAPS and the
implanted IPG. The WT uses the FCC-approved MICS band (~403 MHz) to communicate with
the IPG at distances of up to 1 m. The WT has a 2 m cable with a USB connector that plugs into
the commercially available laptop. The WT is powered via the USB connection on the laptop
and does not require any additional power source, such as its own battery or additional power
connection.
