Cautions:
▪
Do not use polypropylene suture material on silicone
components. Polypropylene may damage the component,
resulting in component failure.
▪
Do not overtighten ligatures on the anchor or connector boot.
Ligatures that are too tight may damage the component.
For the EZ anchor: Make a ligature, pass the suture around the anchor
and make another ligature. Use a minimum of 4 sutures. Suture the
anchor to the supraspinous ligament or deep fascia.
For the winged anchor: Tie ligatures around the grooves in the middle
of the anchor to secure the anchor to the lead. Next, suture the anchor to
the supraspinous ligament or deep fascia.
Note: Laboratory testing has shown that injecting silicone medical
adhesive between the anchor and lead after tying the ligatures increases
the anchor-to-lead holding force.
3. If desired, use the external neurostimulator to verify that the location of
the lead and the pattern of stimulation have not changed.

Tunneling the lead for direct connection to a neurostimulator

Creating a subcutaneous pocket for the neurostimulator
1. Make an incision equal to the length of the neurostimulator.
2. Use blunt dissection to create a subcutaneous pocket.
Note: Refer to the neurostimulator implant manual for the proper
subcutaneous pocket depth.
Tunneling the lead
Note: If a longer tunneling tool is desired, a Medtronic tunneling tool
accessory kit may be used.
1. After simulating the tunneling route, mark the patient's skin at the
neurostimulator pocket. (The neurostimulator should be placed on the
opposite side of the body from another active implanted device and should
be placed preferably on the right side of the body to allow for future
placement of cardiac devices on the patient's left side.)

Cautions:
▪
When routing the lead, avoid sharp bends or kinks, which may
break the wires. Broken wires may create an open circuit,
resulting in loss of stimulation or component failure and
requiring surgical replacement.
▪
When routing two lead bodies, assure that the area between
them is minimized (Figure 5). If the lead bodies are routed in a
loop and the patient is exposed to some sources of
electromagnetic interference (eg, theft detectors), the patient
may perceive a momentary increase in stimulation, which some
patients have described as uncomfortable stimulation (jolting or
shocking sensation).
