Impulse Dymanics OPTIMIZER Smart System - Resetting Device Counters; 27 Measuring Lead Impedances

26.2 Resetting Device Counters
In order to reset the OPTIMIZER Smart IPG Statistics counters to zero:
• Place (or replace, if necessary) the Programmer Wand over the OPTIMIZER
Smart IPG implant site.
• Select the Statistics button on the Task Bar.
• Select the Reset button at the bottom of the Statistics bar.
As this operation resets the internal counters of the device, a confirmation message will
pop up. If the reset request is confirmed, the reset operation is performed.
If the statistical counters are successful reset, the Programmer reports “Reset statistics
OK”.
However if the Programmer Wand is not well positioned over the implant site, the
resetting operation may fail. If a failure in communication occurs, the Programmer will
display the message “Reset Statistics Error” along with the options Retry and Cancel.
Retry can be performed by repositioning the Programmer Wand and selecting the Retry
button.
27. MEASURING LEAD IMPEDANCES
The impedance of the LS and V leads can be measured by the OPTIMIZER Smart IPG and
displayed by the OMNI Smart Programmer. A CCM signal is delivered through the selected
channel by the OPTIMIZER Smart IPG in order to measure the lead impedance. A pulse train
with the following parameters is used for impedance measurement:
• Number of Pulses: 1
• Amplitude: 5.0
• Phase Duration: 0.5 ms
The impedance of the selected channel can be measured by the OPTIMIZER Smart IPG within
the range 50Ω to 2000Ω to within a precision of 20% or 10Ω, whichever is greater.
Warning: Lead impedance measurements above 1000Ω are very imprecise and must be
construed only as an indication of electrical continuity through the lead.
During the impedance measurement, all programmed parameters remain the same, except for the
ones described above, which are transitorily changed. However, impedance measurement cannot
be performed if a triggering event does not occur, or if an inhibiting event occurs, for the
parameter values programmed in the device.
To measure the lead impedances:
• Place (or replace, if necessary) the Programmer Wand over the OPTIMIZER Smart IPG
implant site.
• Verify that the CCM Train Delivery parameter is set to Timed or Continuous.
• Select the Follow Up button on the Task Bar.
• Select the Impedance tab on the Follow Up bar.
• Select the V or LS button to measure the desired lead impedance.
