Cautions:
#
■ When routing the extension, 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 two leads are implanted, route the lead-extensions so
the area between them is minimized (Figure 2). If the lead-
extensions 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).

2. After assembling the tunneling tools, make an incision at the exit site.
3. Begin at the exit site and tunnel subcutaneously to the lead incision.
Notes:
Deep tunneling is not desirable.
■
Avoid the lower thoracic ribs.
■
■ If the tunneling tool does not extend to the lead-extension connection
site, make an intermediate incision.
4. Use blunt dissection to form a tunnel from the lead incision to the lead-
extension connection site.
5. After tying a ligature to the handle of the percutaneous extension, gently
pull the extension through the passing straw to the exit site.

Connecting the percutaneous extension to the lead

Caution: Before connecting components, wipe off any body fluids and dry
#
all connections. Fluids in the connections may result in stimulation at the
connection site, intermittent stimulation, or loss of stimulation.
1. After disconnecting the short stylet from the lead, slip the connector boot
onto the lead body with the open end of the connector boot facing outward,
exposing the lead contacts.
Note: Irrigate the connector boot with a nonionic antibiotic solution. Dry
the interior of the boot.
2. Wipe the lead body and extension setscrew connector junction with sterile
gauze. If necessary, use sterile (USP) water or a nonionic antibiotic
solution. Dry all connections.
3. Insert the lead connector fully into the extension setscrew connector
junction.
Note: Each lead contact must be aligned under each setscrew.
