The wound will then be dressed to allow healing. 

 

If you decide to get an implanted Evoke System, the leads will be inserted at a similar 
location after your wounds from the trial have healed (see Section 6). 

Note: 

You may notice some differences between stimulation during the trial and with the 

implanted stimulator, as the permanent leads may not be implanted in exactly the same 
place as the trial. 

If you had a lead extension implanted and decide to get an implanted Evoke System: 

 

The lead extensions will be removed, but the leads will remain implanted and connected 
to your implanted stimulator (see Section 6). 

 

If your implant surgery is scheduled for a later date after the trial period ends: 

o

 

At the end of the trial, the lead extension will be cut and remain under the skin 
in your back and the leads will remain implanted in the same place. 

o

 

The wound will then be dressed to allow healing. 

o

 

When you receive the fully implantable system, the remaining cut lead 
extensions will be removed and the leads that remained implanted after the trial 
will be connected to your implanted stimulator (see Section 6). 

If you had a lead extension implanted and decide not to get an implanted Evoke System: 

 

The leads, anchors and lead extensions will be removed. 

 

The wound will then be closed and dressed to allow healing. 

5.5  The eCLS 

Figure 5.1: The eCLS case. Your clinician will connect the eCLS to leads or lead extensions 

inside the eCLS case. Do not open the eCLS case. 

5.5.1  Using the eCLS 

The trial leads or lead extensions are connected to lead adapters and the lead adapters are 
connected to the eCLS by your clinician. Your clinician will then place the eCLS inside the eCLS 
case (see Figure 5.1). During the trial stimulation period, you may wear the eCLS, in its case, in a
