26. Form an appropriately-sized pocket using blunt dissection on either side of midline for coiled excess
lead and extension connectors.
27. Place a small loop at the lead for slack. If necessary, loosely tie a suture around the lead-loop, but do
not tighten onto the lead.
CAUTION: Tightening sutures directly on the lead can damage the lead. In addition, during an MRI scan, the
patient could be at risk of tissue heating, resulting in tissue damage or serious patient injury.
28. Carefully remove excess slack by gently pulling the extensions from the exit wound.
29. For Permanent Trials, if desired, a small suture may be used to close the exit wound of the extension.
Place and tape a stress relief loop and dress the wound. Proceed to the instructions to "Insert the
Leads into the OR Cable Connector" in the appropriate Clinician Trial Manual.
30. For Permanent Implant, close the midline incision, and refer to instructions for "Connecting the Lead to
the IPG" in the IPG Directions For Use for your SCS System.
Removal of Lead or Extension
Remove bandages and properly cleanse the exit site. The method of removal depends upon whether a
temporary trial or permanent trial was performed.
Option A: Percutaneous Lead Removal After Temporary Trial
31. Clip sutures if used to secure the trial lead(s) in place.
32. Remove the lead(s) and discard.
33. To replace the trial lead(s) with permanent Avista MRI percutaneous lead(s), proceed to the
instructions for "Percutaneous Lead Placement in the Epidural Space" in this manual.
Option B: Removal of Lead Extension after Permanent Trial
34. Open the midline incision to expose the lead extension and connector.
35. Cut the lead extension at the connector. Do not cut the implanted lead.
