Intra-Operative Programming with the CI
Note: The Evoke SCS System Surgical Guide provides specific information about surgical
procedures and necessary connections between leads/extensions/lead adapter/CLS/eCLS
as required for the various procedures.
Note: Neither the CI nor the CST are supplied sterile and should not be used inside the
sterile field during intra-operative programming; see Evoke SCS System Surgical Guide for
details.
5.1
Confirmation of Optimal Lead Placement
Physicians may have a preference on the method to confirm optimal lead placement in the
operating room. Lead position may be confirmed anatomically using fluoroscopy,
neurophysiologically using external neuromonitoring equipment, or ECAP measurement
and/or through paresthesia mapping using intraoperative patient feedback.
Following lead placement based on required anatomical location, the surgeon connects the
leads to the lead adapters and the lead adapters to the lead adapter cable and extension
inside the sterile field (see Evoke SCS System Surgical Guide for details). The surgeon passes
the end of the lead adapter extension out of the sterile field to the programming clinician.
5.1.1
Connect the lead adapter extension to the eCLS
This section is to be completed by the programming clinician outside of the sterile field.
1.
Connect the lead adapter cable (or lead adapter extension) to the eCLS (refer to
Figure 5.1).
Figure 5.1: Connect the lead adapter cable (or lead adapter extension) to the eCLS.
5.1.2
Confirmation of optimal lead placement
Confirmation of optimal lead placement may use ECAP measurement (Section 5.1.2.1)
and/or paresthesia mapping (Section 5.1.2.2) to confirm medio-lateral lead location,
dermatomal coverage, ability to measure ECAPs, and/or paresthesia coverage of the
pain areas.
