eCLS from the lead adapter extension.

The surgeon then disconnects the lead adapter from the lead.
5.2
Confirmation of Proper CLS Connection
This task is only performed if a CLS is being implanted. The surgeon creates a pocket for
the CLS and tunnels the leads and/or extensions to the CLS pocket. The surgeon inserts the
proximal connector end of the leads and/or extensions into the ports in the header of the
CLS and places the CLS partially into the CLS pocket.
Programming clinician tasks:
1.
Connect the CI to the CLS via the radio link (see Section 8.1).
2.
Check electrode impedance using the CI to ensure the proximal connectors are
connected properly (see Section 8.1).
o
If electrode impedance is greater than 4000Ω check all the connections.
o
Check impedance after each reconnection of the proximal connector to the CLS
header block.
3.
The surgeon tightens the set-screw on the CLS header when satisfied that there is a
proper connection.
o
Always check the impedance before tightening CLS header set-screw.

Post-Operative Procedures
The stimulator (eCLS or CLS) can be programmed when the patient has recovered
sufficiently to interact with the programming clinician.
1.
Train the patient on use of the EPC, eCLS or CLS and guidelines for recovery
after implant surgery (see Evoke SCS System User Manual).
2.
If the patient has a CLS, also train them on correct use of the Evoke
System Charger (see Evoke SCS System User Manual).
3.
If the patient has externalized leads for a temporary trial using an eCLS, go to
Section 6.1. (Connecting an eCLS to Externalized Leads).
4.
If the patient has an implanted CLS, go to Section 7 ‘Clinical Programming -
Introduction’.
Caution: Aspects of the therapy may change with time due to lead movement or as
the patient becomes accustomed to the stimulation. You may reprogram the patient’s eCLS
or CLS if required at any time.

Connecting an eCLS to Externalized Leads
6.1.1
Connect the lead to the lead adapter
1.
Place the tip of the proximal connector end of the lead into the end of the lead
adapter slot.
