▪
Discard the torque wrench after making all connections.
Reusing a torque wrench may result in undertightening or
overtightening and subsequently, intermittent or loss of
stimulation.
5. Using minimal force, pull on the connections to ensure they are secure.
6. Confirm the integrity of the connections by rechecking the stimulation
pattern.
7. Slide the connector boots over the lead-extension connections and tie a
ligature (using nonabsorbable silk) between the pairs of rings at both ends
of each connector boot.

Cautions:
▪
Do not use polypropylene suture material on silicone
components. Polypropylene may damage the component,
resulting in component failure.
▪
Do not tie ligatures around the lead or extension body, which
may damage the insulation.
▪
Do not overtighten ligatures on the connector boot. Ligatures
that are too tight may damage the component.
▪
Ensure that the end of the connector boot is secure to prevent
fluid in the lead-extension connection, which may result in
stimulation at the connection site, intermittent stimulation, or
loss of stimulation.

Creating strain-relief loops and suturing the connector boots

#
Caution: Use strain-relief loops as directed when implanting surgical
leads. Implanting surgical leads without strain-relief loops may reduce the
functional survival time of the lead, requiring reprogramming and/or early
replacement of the lead to restore effective therapy.
1. While maintaining lead position, create a strain-relief loop with each of the
lead bodies, by coiling the lead bodies near the connector boots
(Figure 3).

#
Cautions:
▪
Do not pull the lead or extension taut. Allow enough slack in the
lead or extension to accommodate patient movement. Pulling
the lead or extension taut may result in a short or open circuit
or migration of implanted components.
▪
Coil the excess lead body into a circular loop greater than 2 cm
(0.8 in) in diameter. Do not use a U-shaped loop or bend
(Figure 4). A circular loop decreases the possibility of
electromagnetic interference and its effects and prevents
kinking or damaging the lead body.
