Securing the Stimulation Lead
The stimulation lead is anchored to the tissues surrounding the hypoglossal nerve. The
suggested method for anchoring the lead body is to anchor it to the digastric muscle using
permanent sutures (Figure 11).
1. Position the cuff and stimulation lead:
• Maintain the cuff and stimulation lead body parallel to the nerve to avoid placing torque
or tension on the nerve.
• It is recommended that the spine of the cuff is positioned inferior to the nerve.
2. Secure the stimulation lead with adequate strain relief by creating a lead loop in between
the stimulation lead cuff and the anchoring site (e.g., digastric muscle).
3. Using both anchor recesses, tie permanent sutures to the anchor, then secure the anchor
to the digastric muscle using the sutures.
4. It is recommended that the physician not close the neck incision until all system
components are implanted and tested. Consider gently packing the neck incision with 4x4
gauze soaked in a saline/antibiotic solution. Remove such packing with care prior to
closing the incision so as not to dislodge or disrupt the cuff placement.
Cautions:
• Make sure that the anchor points are located in tissue that moves with the
hypoglossal nerve.
• Do not loop the lead such that the lead body crosses and touches itself.
Crossing the lead bodies can result in fibrosis at the intersection point and
reduce strain relief in the lead body.
• Place sutures only around the anchor region of the lead.
• Surgical instruments should not be used to handle the lead body directly. The
lead is easily kinked and the insulation is easily damaged. Care should be
used when handling the lead. Surgical instruments may be used for handling
the lead anchor.
