Physician Lead Manual Sterilization and Handling Sterilization The Advanced Bionics Lead Model SC 2108 and Lead Extension Model SC 3108 and accessories (except for the Lead Position Labels) were sterilized with ethylene oxide prior to shipment. Red lines on the green tape located near the bottom of the inner tray cover indicates exposure to the sterilization process. Inspect the condition of the sterilization indicator and the sterile package before opening the package and using the contents.
Sterilization and Handling • Avoid pulling an implanted lead taut; provide a stress relief loop at the insertion site to minimize tension on the lead. • Avoid handling the lead with sharp instruments; use only rubber-tipped forceps. • Take care when using sharp instruments such as hemostats or scalpels to prevent damaging the lead. • Wipe off any body fluids from the lead connector end before connecting it to any other component.
Physician Lead Manual Guidelines for Trial-phase Implantation This section details the recommended procedures for trial-phase temporary implantation of the lead. Pre-op Instructions 12 • Check that the sterile package is intact. (See “Sterilization” on page 10.) • Ensure that a Trial Stimulator and Patient Trial Kit are available for use following lead placement. Install a new 6 volt battery (included in the Patient Trial Kit) in the Trial Stimulator.
Guidelines for Trial-phase Implantation Lead Placement Note: Fluoroscopic evaluation of the lead position during this procedure will aid the physician in achieving an optimum pain coverage location, and is recommended. 1. Position, prep and drape the patient in the usual accepted manner. Inject a local anesthetic at the needle insertion site. 2. Insert the needle into the epidural space with the opening facing up using an angle of 45° or less. Use only the insertion needle provided in the Lead Kit.
Physician Lead Manual 4. OPTIONAL. Under fluoroscopic guidance, insert the lead blank through the needle and into the epidural space. Advance the lead blank to the target location, then withdraw the blank. 5. Slowly insert the lead, with stylet, through the needle (lead stylet should extend completely to the tip of the lead). 6. Advance the lead to the appropriate vertebral level using fluoroscopic guidance. A sufficient length of lead (i.e.
Guidelines for Trial-phase Implantation Connecting the OR Cable Assembly The OR cable extension is designed for temporary connection to the OR cable to facilitate stimulation testing outside of the sterile field. After stimulation testing, the cable extension is typically removed and the OR cable is connected directly to the Trial Stimulator for use during the trial phase. Do not immerse the OR cable connector or plug in water or other liquids.
Physician Lead Manual 5. Push the end of the lead into the port until it stops. Hold the lead in place while sliding the locking lever to the “1” (locked) position. Note: Once the lead is secured in the connector, the stylet can be manipulated in, but not removed from, the lead.
Guidelines for Trial-phase Implantation 6. Plug the OR Cable Assembly into the Trial Stimulator socket(s) labeled 1-L (left) and 2-R (right). Superior (upper or left) leads connect to socket 1-L. Inferior (lower or right) leads connect to socket 2-R. If only a single lead is being used, connect it to 1-L.
Physician Lead Manual Intraoperative Stimulation Testing Note: The following steps are for procedural reference only. Please refer to the Physician Systems Handbook for detailed stimulation testing procedures and guidelines. 1. Test various electrode configurations to obtain paresthesia. Note: If lead repositioning is necessary, turn stimulation off before proceeding. 2. 3.
Guidelines for Trial-phase Implantation 4. Once the needle tip is exposed, hold the lead as close to the percutaneous exit site as possible, then carefully pull the needle completely from the lead. 5. If desired, a small suture may be used to close the wound and stabilize the lead. Place and tape a stress relief loop and dress the wound. 6. Continue with “Connecting to the Trial Stimulator” on page 28.
Physician Lead Manual OPTION B: Permanent Lead Trial Removing the Needle 1. Cut down around the needle to access the supraspinous ligament. 2. Hold the lead distal to the needle hub to maintain lead position during needle removal. 3. Carefully withdraw the insertion needle from the epidural space by slowly pulling the needle up towards the proximal end of the lead. 4. Continue to pull the needle back approximately one centimeter at a time until the needle tip is exposed.
Guidelines for Trial-phase Implantation 5. Once the needle tip is exposed, hold the lead as close to the tip as possible, then carefully pull the needle completely from the lead. Anchoring the Lead 1. Place a suture through the supraspinous ligament or deep fascial tissue. 2. Slide a suture sleeve over the lead and down to the supraspinous ligament. 3. Ligate the sleeve onto the lead by tying a 2-0 silk or other nonabsorbable suture around the center groove of the sleeve to prevent sliding.
Physician Lead Manual 4. Suture the sleeve to the supraspinous ligament or deep fascia through the suture sleeve holes. Tunneling And Connecting Extension A tunneling tool and straw are provided with the Lead Extension Kit to facilitate percutaneous tunneling of the lead or extension. • 22 Attach the tunneling tool handle to the shaft by turning the locking mechanism clockwise.
Guidelines for Trial-phase Implantation 1. Mark the desired route of the tunnel. 2. Administer the appropriate local anesthetic along the tunneling path. 3. Make a small incision at the desired exit site.
Physician Lead Manual 4. Create a subcutaneous tunnel from the exit site to the midline incision until the straw is visible and accessible at the exit point. 5. Unscrew and remove the tool handle.
Guidelines for Trial-phase Implantation 6. Grasp the tip of the tool with one hand while holding the straw in place with the other hand. Pull the tunneling tool shaft out through the straw. 7. Push the lead or extension proximal ends through the straw, then withdraw the straw. 8. Wipe clean the proximal end of the lead, then insert the proximal end into the extension connector until it stops and the last contact disappears.
Physician Lead Manual 9. Using the torque wrench supplied, turn the extension connector setscrew clockwise until it clicks, indicating lock. Note: • Ensure the wrench is fully seated in the setscrew before tightening. • The wrench is torque-limited and cannot be overtightened. 10. Form an appropriately-sized pocket using blunt dissection on either side of midline for coiled excess lead and extension connectors. 11. Place a small loop at the lead for slack.
Guidelines for Trial-phase Implantation Tightening sutures directly on the lead can damage the lead. 12. Carefully remove excess slack by gently pulling the extensions from the exit wound. 13. Close the midline incision. 14. 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.
Physician Lead Manual Connecting to the Trial Stimulator 1. Wipe fluids off the exposed lead connections. 2. Disconnect and discard the excess OR cable extension, unless extra length is needed for trial use. 3. Connect the OR cable(s) to the lead(s) or lead extensions: Slide the locking lever to “0,” fully insert the end of the extension into the port, slide the locking lever to “1.” 4. Connect the cable labeled 1-L to the upper or left lead, and the cable labeled 2-R to the lower or right lead.
Connecting to the Trial Stimulator 6. Fit the Velcro® belt to the patient, cut off the excess length, and place the Trial Stimulator in the belt pocket.
Physician Lead Manual Guidelines for Permanent Implantation This section details the procedures for • tunneling the lead/extension as part of an IPG implant • connection of lead/extension to the IPG The Tunneling Tool Assembly used in this procedure is provided with the Precision device as part of the IPG Kit. Percutaneous Lead/Extension Removal Before revising a trial system for chronic stimulation, the exposed portion of the lead or extension must be removed.
Guidelines for Permanent Implantation Option B. Extension Removal 1. Open the midline incision to expose the lead and connector. 2. Cut the lead extension at the connector. 3. Pull the lead extension through the tunnel and away from body at the externalized site. 4. Loosen the connector setscrew using the torque wrench provided. Disconnect and remove the connector. Note: Connect a new lead extension, if necessary, to reach the selected IPG site.
Physician Lead Manual IPG Implantation 1. Ensure that the area surrounding the lead entry site is incised to a dimension that will accommodate the tunneling tool. Check that the lead is securely sutured with the suture sleeve. 2. Select and mark the intended IPG site several inches away from the previously externalized leads, and create an incision at the top of the site. 3. Create a subcutaneous pocket no larger than the IPG outline at a depth of up to 3/4 inch (2.0 cm) from the surface.
IPG Implantation Tool Assembly The tunneling tool provided with the IPG includes a shaft extender to be used for up to two leads (with or without extensions). 1. Attach the handle to the tunneling tool shaft by turning the locking mechanism clockwise. Note: For more length, attach the shaft extension to the handle, and then attach the carrier shaft. 2. Thread the tip cover onto the tunneling tool and tighten by turning clockwise. Tunneling The Lead 1. Mark the desired route of the tunnel. 2.
Physician Lead Manual Note: Check that the tunneling tool tip is securely threaded onto the carrier. 3. OPTIONAL. If necessary, bend the tool shaft to conform to the patient’s body. Do not bend locking joints. 4. Create a subcutaneous tunnel from the IPG site to the midline incision. Note: Deep tunneling is not recommended.
IPG Implantation 5. Once the tunneling tip is completely exposed at midline, press it toward the shaft and turn it counterclockwise to remove it for access to the carrier. Note: You may feel the tip slide back before the cover begins to unscrew.
Physician Lead Manual 6. Carefully position each lead or extension into the carrier shaft and press the lead/extension into the groove. Note: If necessary, swivel the carrier by pulling it away from the handle and turning it to get better access to the cavities. 7. 36 Gently pull the tunneling tool back through the tunnel.
IPG Implantation 8. Gently lift the lead(s) out of the locking groove(s). 9. Wipe off any fluids from the proximal end of the lead(s). Connecting To the IPG Before implanting the IPG, refer to the IPG Implant Manual. Dual Lead Connection • Superior (upper or left) leads connect to IPG port 1-L. • Inferior (lower or right) leads connect to IPG port 2-R. Single Lead Connection • Connect a single lead to IPG port 1-L. • Plug port 2-R with the connector plug supplied in the IPG Kit.
Physician Lead Manual 1. Fully insert the lead(s) into the IPG port(s). When the lead is properly inserted, the lead will stop and the retention ring will be located under the setscrew. 2. Pass the torque wrench through the slit in the septum located on the top of the IPG header and tighten both set screws, one at a time, until the torque wrench “clicks,” indicating lock.
IPG Implantation Note: • If the connector plug is used in port 2-R, it is still necessary to tighten the setscrew as described. • The wrench is torque-limited and cannot be overtightened. • Ensure that the lead is fully inserted before tightening the setscrew to prevent lead damage. 3. Place the IPG in the subcutaneous pocket with “This Side Up” facing anterior towards the skin. 4. Coil excess lead or extension under the IPG. Note: To confirm good connections, check impedances. 5.
