ESCRIPTION

The Freedom Spinal Cord Stimulation System is used for Spinal Cord Stimulation (SCS) to aid in the relief of chronic, intractable pain of the trunk and/or limbs. The therapy utilizes pulsed electrical current to stimulate nerves near the spinal cord in order to inhibit the transmission of pain signals to the brain. The system consists of a neurostimulation lead that is placed in the epidural space of the patient and an external power unit, the Malibu Wearable Antenna

Assembly (WAA) that transmits power wirelessly through the skin to the implanted lead. The implantable lead is a sealed, self-contained system that can include or be mated to a receiver that generates stimulation waveforms to create an electrical volume conduction from the electrode array at the distal end of the lead. The Malibu WAA is the external power unit that is programmable to allow for adjustment of stimulation parameters including the waveform pulse rate, duration, and amplitude.

I

NDICATIONS

The Freedom SCS System is indicated for use as a therapy for:

• Failed Back Surgery Syndrome (FBSS);

• Complex Regional Pain Syndrome (CRPS), Reflex Sympathetic Dystrophy (RSD), or

Causalgia;

• Radicular Pain Syndrome or Radiculopathies;

• Post Laminectomy Pain;

• Multiple Back Surgeries;

• Unsuccessful Disk Surgery or Spinal Decompression Surgery;

• Degenerative Disk Disease (DDD) / herniated disk pain refractory to conservative and surgical interventions;

• Peripheral Causalgia;

• Epidural Fibrosis; and,

• Arachnoiditis or Lumbar Adhesive Arachnoiditis.

English

Page | 4

C

ONTRAINDICATIONS

Patients contraindicated for the Freedom SCS System are those who:

• Are poor surgical risks;

• Are pregnant;

• Are unable to operate the SCS system;

• Are exposed to short-wave diathermy, microwave diathermy or therapeutic ultrasound diathermy; and,

• Are occupationally exposed to high levels of non-ionizing radiation that may interfere with the therapy delivered.

P

RECAUTIONS

The Freedom SCS System could be impacted by operational changes to the Malibu Wearable

Antenna Assembly (WAA) through interference by strong electromagnetic interference (EMI) sources (e.g. diathermy, electrocautery, MRI, radio-frequency ablation, etc.). Should the system ever stop or change performance characteristics as a suspected result of EMI, turn off the system immediately and remove the source of EMI from proximity. Refer to the User

Manual for a detailed list of precautions.

UMMARY

Implanting a neurostimulation system has risks similar to other spinal procedures. If you are on anticoagulation therapy you might be at greater risk for postoperative complications such as hematomas that could result in paralysis.

In addition to those normally associated with surgery, implantation of a neurostimulation system includes the following risks:

• Allergic or immune system response implanted materials

• Infection;

• Lead erosion through the skin or lead migration;

• Leakage of cerebrospinal fluid;

• Loss of therapy effectiveness;

• Epidural hemorrhage, hematoma, or paralysis;

• Radicular chest wall stimulation;

• Change in stimulation, possibly related to cellular changes around the electrode(s), migration of lead position, electromagnetic interference, or lead fracture.

RANSITION

Before a permanent Freedom SCS System is prescribed to a patient, a trial system can be first implanted to evaluate the effectiveness of the therapy for the patient. A trial neurostimulator

(FRT4) can be implanted for such therapy evaluation; results should be reviewed at the end of the trial period to determine if the pain relief was satisfactory for the patient. Considerations before moving to a permanent implant may also include if the patient experiences any adverse events, if the patient has any difficulty operating the Malibu WAA, if the patient had sufficient and comfortable levels of paresthesia coverage and pain relief.

REPARING FOR SURGERY

Before opening the lead package, verify the package integrity, model number, and use-by date.

In the event that the package is damaged, do not use the product. In the event that the use-by date has expired, do not use the product. Contact Stimwave for further service.

C

AUTION

:

To reduce the risk of lead damage that my result in intermittent stimulation or loss of stimulation, requiring additional surgery to replace the lead:

§

Use only the needle and introducer sheath supplied in the kit.

§

Use a shallow needle-insertion angle (45 degrees or less) when inserting or withdrawing the needle into or out of the epidural space.

§

Do not bend, kink, or stretch the lead or stylet, which may damage the components.

§

Do not use any instrument to handle the lead. The force may compress the lead, resulting in the fracture of internal electronics or inability to insert or withdraw the stylet.

§

Use care when replacing a stylet, excessive pressure on the lead could damage the components, resulting in intermittent or loss of stimulation.

W

ARNING

:

Select a needle entry location that is not more than two vertebral spaces below the target stimulation site.

As with any spinal procedure, the risk of serious injury to the patient (e.g. hemorrhage, hematoma, or paralysis) increases as location of the selected needle insertion site progresses up the vertebral column – from a lower risk at a lumbar location to a higher risk at a cervical location. Select a vertebral location that provides the widest and easiest access to the epidural space during needle insertion to reduce the risk of serious patient injury resulting from direct trauma to the spinal cord.

English

Page | 12

P

LACING A LEAD

1. If necessary, make an incision at the needle-entry site to the depth of the subcutaneous fascia.

2. Using a paramedian approach lateral to the midline, and under fluoroscopy, insert the introducer sheath and needle assembly into the epidural space at a shallow angle until you encounter resistance from the ligamentum flavum (See Figure 1).

NOTE: Do not use any other needle or introducer sheath other than the ones provided in the lead kit. Do not remove the introducer sheath from the epidural needle when driving

the needle into the epidural space.

FIGURE 1. INSERT THE INTRODUCER SHEATH AND NEEDLE ASSEMBLY INTO THE EPIDURAL SPACE.

English

Page | 13

FIGURE 2. INTRODUCER SHEATH AND NEEDLE ASSEMBLY IN EPIDURAL SPACE.

3. Confirm introducer sheath and needle location under fluoroscopy (See Figure 2).

4. After rotating the introducer sheath and needle assembly so that the beveled edge faces cephalad, remove the needle stylet.

5. Advance the introducer sheath and needle assembly to confirm entry into the epidural space (e.g. using the loss-of-resistance technique with air or sterile water).

6. For a second lead, repeat steps 1 – 5 noting these recommendations:

§

Implant the second lead parallel to the first lead and approximately 1 – 3 mm lateral of the physiological midline.

§

Introduce the second lead one vertebral space below the first lead to help prevent nicking or cutting the first lead and to allow sufficient space for suturing both lead and anchors.

§

Stagger the lead tips or place them several vertebral spaces apart, depending on the position that produces the most effective paresthesia.

English

Page | 14

C

AUTION

:

Do not use contrast media or saline flush. Contrast media may obscure the field of view and a saline flush may increase the difficulty of lead placement.

7. After inserting the guide wire through the needle, advance the guide wire no farther than 1 -3 cm past the needle tip. Next, remove the guide wire from the needle.

NOTE: If the guide wire track deviates from the intended pathway, steering and manipulating the lead will be more difficult.

8. Next, remove the needle while maintaining the position of the introducer sheath (Figure

3).

NOTE: The metal needle blocks the energy from the Malibu WAA and cannot be used during intraoperative stimulation.

FIGURE 3. INTRODUCER SHEATH REMAINS IN EPIDURAL SPACE WHILE THE NEEDLE IS REMOVED.

English

Page | 15

9. Using fluoroscopy, slowly insert the lead through the introducer sheath and advance the lead to the initial target placement site (See Figure 4). A stylet may need to be reinserted. The Introducer Sheath is RF transparent, and can be used throughout intraoperative testing of the lead.

NOTE: When using a curved stylet and resistance is encountered during lead advancement, exchange the curved stylet for the straight stylet and use short, firm movements to advance the lead.

FIGURE 4. PASS THE LEAD THROUGH THE INTERIOR LUMEN OF THE INTRODUCER SHEATH.

10. After verifying the lead position under fluoroscopy (anterior-posterior and lateral views), compare that location with the location that has the highest probability of paresthesia coverage.

NOTE: To increase lead stability, insert enough lead length to extend at least three vertebral bodies into the epidural space. Position the lead so that the center electrodes will be active if lead migration occurs.

NTRAOPERATIVELY

NOTE: This procedure requires a Malibu Wearable Antenna Assembly. The Malibu WAA is packaged in a separate kit. Refer to the User Manual for instructions on how to use the Malibu

WAA.

1. While holding the lead in place, disconnect the stylet handle from the lead (proximal end), and completely withdraw the stylet.

2. Place the Malibu Wearable Antenna Assembly in a sterile drape or sterile fluoroscope bag in the region directly above the most proximal implanted electrode (See Figure 5).

C

AUTION

:

To prevent possible uncomfortable or unexpected stimulation (jolting or shocking sensation):

§

Program parameter changes in small increments above the perception threshold

(the amplitude value(s) at which the patient first perceives paresthesia).

§

Decrease the amplitude(s) before: o Changing electrode polarities. o Placing the on the patient’s back. o Turning ON the neurostimulator.

3. Identify the most appropriate stimulation parameters, beginning at a medium pulse width and frequency range.

NOTE: The frequency, pulse width and amplitude are all parameters that collectively make up the stimulation therapy that the patient receives.

English

Page | 17

FIGURE 5. INTRAOPERATIVE STIMULATION USING THE MALIBU WEARABLE ANTENNA ASSEMBLY.

4. Increase the amplitude while asking the patient close-ended questions to identify the perception threshold (the amplitude at which the patient first perceives paresthesia), the discomfort threshold (the amplitude at which paresthesia is beyond the patient’s tolerance), and the paresthesia coverage.

NOTE: If good paresthesia coverage is not attained, change electrode settings before repositioning the lead to confirm the direction of lead movement.

5. If two leads were placed, repeat steps 3 – 4 for the second lead; optimize paresthesia coverage using both leads.

6. In the patient’s chart, document the lead position that provided appropriate stimulation coverage (i.e. record the settings and patient responses and include a fluoroscopic image of the final lead position).

P

REPARATION FOR THE

MRI

EXAMINATION

The following steps are required prior to performing an MRI examination on a patient who has an implanted Freedom FRT4 or FRE4 component.

1. Allow at least six weeks from the date of implantation to the time of MRI examination.

2. Remove the Malibu Wearable Antenna Assembly (e.g., the external component of this neuromodulation system) from the patients before entering the MR system room.

3. Determine if the patient has any other implants or health conditions that would prohibit or contraindicate an MRI examination. Do not conduct an MRI examination if conditions or implants that would prohibit or contraindicate the MRI procedure are present. If the patient has another implant or device, the safety of performing MRI with the Freedom

SCS lead is unknown.

4. Instruct the patient to immediately inform the MR system operator (i.e., the MRI technologist) if any discomfort, stimulation, shocking, or heating occurs during the examination.

5. The patient must be conscious during the MRI examination in order to be able to inform the MR system operator of any heating, discomfort, or other problems.

6. Verify that all proposed MRI conditions comply with the specific requirements in this manual. If not, the MRI conditions must be modified to meet these requirements. If a particular parameter cannot be modified, do not perform the MRI examination.
