*Sub-perception stimulation has been demonstrated to be safe and effective in patients who have been treated successfully with conventional, paresthesia-inducing stimulation for at least six months. Full stimulation parameter ranges and options for both paresthesia based and sub-perception therapy are available for clinician’s use throughout the patient’s experience and treatment with SCS. **Combination therapy is 1khz plus standard rate.
The Boston Scientific Spinal Cord Stimulator Systems are indicated as an aid in the management of chronic intractable pain of the trunk and/or limbs including unilateral or bilateral pain associated with the following: failed back surgery syndrome, Complex Regional Pain Syndrome (CRPS) Types I and II, intractable low back pain and leg pain. Associated conditions and etiologies may be: radicular pain syndrome, radiculopathies resulting in pain secondary to failed back syndrome or herniated disc, epidural fibrosis, degenerative disc disease (herniated disc pain refractory to conservative and surgical interventions), arachnoiditis, multiple back surgeries.
Patients contraindicated for permanent SCS therapy are those who:
- are unable to operate the SCS system
- have failed trial stimulation by failing to receive effective pain relief
- are poor surgical risks
- are pregnant
Unauthorized modification to the medical devices is prohibited. System integrity could be compromised and harm or injury to the patient could occur if the medical devices are subjected to unauthorized modification.
Heat Due to Charging.
Patients should not charge while sleeping. This may result in a burn. While charging, the Charger may become warm. It should be handled with care. Failure to use the Charger with either the Charging Belt or an adhesive patch, may result in a burn. If patients experience pain or discomfort, they should cease charging and contact Boston Scientific.
Magnetic Resonance Imaging (MRI).
The Spectra WaveWriter SCS System with ImageReady MRI Technology is “MRI-Conditional” only when exposed to the MRI environment under the specific conditions defined in the ImageReady™ MRI Guidelines for Spectra WaveWriter Spinal Cord Stimulator System.
The safety and effectiveness of spinal cord stimulation has not been established for pediatric use.
Shortwave, microwave and/ or therapeutic ultrasound diathermy should not be used on SCS patients. The energy generated by diathermy can be transferred through the Stimulator system, causing tissue damage at the lead site and resulting in severe injury or death. The IPG, whether it is turned on or off, may be damaged.
Implanted Stimulation Devices.
Spinal cord stimulators may interfere with the operation of implanted sensing stimulators such as pacemakers or cardioverter defibrillators. The effect of implanted stimulation devices on neurostimulators is unknown.
Burns may result if the pulse generator case is ruptured or pierced and patient tissue is exposed to battery chemicals. Do not implant the device if the case is damaged.
Patients should be advised that changes in posture or abrupt movements may cause decreases, or uncomfortable or painful increases in the perceived stimulation level. Patients should be advised to turn down the amplitude or turn off the IPG before making posture changes. If using therapy that does not produce a sensation (subperception), postural changes are less likely to affect the patient. Important: If unpleasant sensations occur, the IPG should be turned off immediately.
Strong electromagnetic fields can potentially turn the Stimulator off, or cause uncomfortable or jolting stimulation or affect wireless communication. Patients should be counseled to avoid or exercise care around:
- Theft detectors or security screeners such as those used at entrances/exits of department stores, libraries, and other public establishments, and/or airport security screening devices. It is recommended that patients request assistance to bypass the device. If they must proceed through the device, the patient should turn off the Stimulator and proceed with caution, moving through the center of the screener as quickly as possible.
- Power lines or power generators
- Electric steel furnaces and arc welders
- Large, magnetized stereo speakers
- Tag deactivators such as those found in retail stores and libraries.
If the patient is near these devices, he may become aware of changing stimulation levels. In rare instances, if the stimulation is on, the patient could experience an increase in stimulation level to the point that the sensation is uncomfortably strong or possibly “jolting.” If this happens, the patient should turn off the Stimulator. If the Stimulator suddenly turns off by itself, the patient should first move away from the area. Next, check the stimulation status with the Remote Control by pressing the Unlock button and observing the screen. The implant may need to be recharged before stimulation can be restarted. The patient can refer to the Charging Handbook for further information.
The patient should be counseled to always be aware of his surroundings, particularly near theft detectors/security screeners. He should ask for assistance to go around these devices if he feels at all uncomfortable.
Physician training is required.
The following medical therapies or procedures may turn stimulation off or may cause permanent damage to the Stimulator, particularly if used in close proximity to the device:
- external defibrillation
- radiation therapy (Any damage to the device by radiation may not be immediately detectable.)
- ultrasonic scanning
- high-output ultrasound
X-ray and CT scans may damage the Stimulator if stimulation is on. X-Ray and CT Scans are unlikely to damage the Stimulator if stimulation is turned off.
If any of the above is required by medical necessity, refer to “Instructions for the Physician” in the DFU.
Ultimately, however, the device may require explantation as a result of damage to the device.
Subperception stimulation has been demonstrated to be safe and effective in patients who have been treated successfully with conventional, paresthesia-inducing stimulation for at least six months. Full stimulation parameter ranges and options for both paresthesia-based and subperception therapy are available for clinician’s use throughout the patient’s experience and treatment with SCS.
Automobiles and Other Equipment.
Patients using therapy that generates paresthesia should not operate motorized vehicles such as automobiles or potentially dangerous machinery and equipment with the stimulation on. Stimulation must be turned off first in such cases. For these patients, any sudden stimulation changes may distract patients from proper operation of the vehicle, machinery, or equipment.
For therapy that does not generate paresthesia (e.e., subperception therapy) it is less likely that sudden stimulation changes resulting in distraction could occur while having stimulation on when operating moving vehicles, machinery, and equipment.
During the two weeks following surgery, it is important that patients use extreme care so that appropriate healing will secure the implanted components and close the surgical incisions:
- Patients should not lift objects of more than five pounds.
- Patients should not engage in rigorous physical activity such as twisting, bending, or climbing.
- If new leads were implanted, patients should not raise their arms above their head.
Temporarily, there may be some pain in the area of the implant as the incisions heal. Patients should be instructed that if discomfort continues beyond two weeks, they should contact their physician.
If patients notice excessive redness around the wound areas during this time, they should contact their physician to check for infection and administer proper treatment. In rare cases, adverse tissue reaction to implanted materials can occur during this period.
Patients should consult their physician before making lifestyle changes due to decreases in pain.
Patients should never attempt to change the orientation or “flip” (rotate or spin) the Stimulator. Patients should not “finger” or play with the Stimulator. If the Stimulator flips over in the Patient’s body, it cannot be charged. If the Patient knows that the device has turned, or if stimulation cannot be turned on after charging, the Patient should contact his or her physician to arrange an evaluation of the system. In some cases, the skin over the Stimulator may become very thin over time. If this occurs, Patients should contact their physicians.
In some instances a lead can move from its original location, and stimulation at the intended pain site can be lost. If this occurs, Patients should consult their physician who may able to restore stimulation by reprogramming the Stimulator in the clinic or repositioning the lead during another operation.
Stimulators can fail at any time due to random component failure, loss of battery functionality, or lead breakage. If the device stops working even after complete charging (up to four hours), Patients should turn off the Stimulator and contact their physician so that the system can be evaluated.
The operating temperature of the Trial Stimulator, Remote Control, and Programming Wand is 10–40 °C (50–104 °F). For proper operation, do not use the Charger if the ambient temperature is above 35 °C (95 °F).
Storage, Handling and Transport.
Do not expose the Remote Control or Charging System components to excessively hot or cold conditions. Do not leave the devices in your car or outdoors for extended periods of time. The sensitive electronics can be damaged by temperature extremes, particularly high heat. If the Remote Control or the Charging System is to be stored for a period of time without batteries, the storage temperature should not exceed -20 to 60 °C (-4 to 140 °F). Handle the system external components and accessories with care. Do not drop them or submerge them in water. Although reliability testing has been performed to ensure quality manufacturing and performance, dropping the devices on hard surfaces or in water, or other rough handling, can permanently damage these components. Refer to the Limited Warranty for additional information. Upon completion of the Patient Trial, remove the batteries from the Trial Stimulator.
Do not dispose of the Remote Control or Charger in fire. The battery in these devices can explode in fire. Dispose of used batteries in accordance with local regulations. The Stimulator should be explanted in the case of cremation, and returned to Boston Scientific. External devices to be disposed of per local regulatory requirements. Please contact your healthcare professional.
Remote Control, Charging System, External Trial Stimulator and Wand Cleaning.
The charging system components can be cleaned using alcohol or a mild detergent applied with a cloth or tissue. The Remote Control, External Trial Stimulator and Programming Wand can be cleaned using a mild detergent applied with a lightly dampened cloth or tissue. Residue from soapy detergents should be removed with a cloth lightly dampened with water. Do not use abrasive cleansers for cleaning. Cleaning wipes for the External Trial Stimulator can also be ordered through Boston Scientific customer service. As an operator of the external devices, perform only the following service and maintenance tasks on the external devices:
- Changing the battery
- Charging the battery
Ensure that the devices are not in use while performing service and maintenance tasks.
While we do not anticipate any interference with cell phones, the full effects of interaction with cell phones are unknown at this time. If there is a concern or a problem is encountered, the patients should contact their physician.
Potential risks are involved with any surgery.
The possible risks of implanting a pulse generator as part of a system to deliver spinal cord stimulation include:
- Lead migration, resulting in undesirable changes in stimulation and subsequent reduction in pain relief.
- System failure, which can occur at any time due to random failure(s) of the components or the battery. These events, which may include device failure, lead breakage, hardware malfunctions, loose connections, electrical shorts or open circuits and lead insulation breaches, can result in ineffective pain control.
- Tissue reaction to implanted materials can occur. In some cases, the formation of reactive tissue around the lead in the epidural space can result in delayed onset of spinal cord compression and neurological/sensory deficit, including paralysis. Time to onset is variable, possibly ranging from weeks to years after implant.
- Skin erosion at the IPG site can occur over time.
- Possible surgical procedural risks are: temporary pain at the implant site, infection, cerebrospinal fluid (CSF) leakage and, although rare, epidural hemorrhage, seroma, hematoma and paralysis.
- External sources of electromagnetic interference may cause the device to malfunction and affect stimulation.
- Exposure to MRI can result in heating of tissue, image artifacts, induced voltages in the neurostimulator and/or leads, lead dislodgement.
- Undesirable stimulation may occur over time due to cellular changes in tissue around the electrodes, changes in electrode position, loose electrical connections and/or lead failure.
- The patient may experience painful electrical stimulation of the chest wall as a result of stimulation of certain nerve roots several weeks after surgery.
- Over time, the Stimulator may move from its original position.
- Weakness, clumsiness, numbness or pain below the level of implantation.
- Persistent pain at the IPG or lead site.
In any event, instruct the patient to contact their physician to inform him/her.
