 Combination Therapy

Combination Therapy


The Spectra WaveWriter SCS System is the first SCS system with combination therapy, the ability to layer waveforms simultaneously. By layering more than one therapy at the same time and delivering multiple therapies over time, combination therapy is designed to provide more thorough and longer-lasting relief to the most patients possible. 

Give your patients the type of stimulation they need—
when and where they need it:


  • Deliver fast-onset pain relief with paresthesia while a slow-onset sub-perception waveform washes in.
  • Layer multiple therapies simultaneously to treat a single pain area such as the low back.
  • Use multiple therapies sequentially, which may help address habituation.
  • Deliver different waveforms to different locations simultaneously for patients with pain in multiple areas.

Sub-Perception Algorithms

Engineered to help you easily find and keep the optimal
target and maintain therapy over time.


Our proprietary Contour™ Field Shaping Algorithm offers a collection of novel, paresthesia-independent, broad field shapes contoured to each patient

Sub-Perception Algorithms


The Spectra WaveWriter SCS System's Contour™ Field Shaping Algorithm delivers sub-perception therapy in new ways.  This proprietary algorithm shapes the stimulation field over multiple vertebral levels to each patient's individual spinal anatomy.

Proprietary Sub-Perception Algorithms Designed to Help You:


  • Easily find and keep the optimal target
  • Address patient variability
  • Preferentially modulate elements in the dorsal horn for effective therapy independent of paresthesia

Waveform Automation

Designed to help you identify the most effective
therapies for personalized pain relief.


The Spectra WaveWriter™ SCS System automatically rotates through different therapies.

Waveform Automation


Engineered for simplicity, the Spectra WaveWriter System can automatically rotate through specific waveforms while allowing patients to enter real-time evaluations on their remote control. By providing critical patient data, the system is designed to help physicians identify the most effective therapies with the least patient burden for personalized relief—both today and as pain changes over time.

INDICATIONS FOR USE

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. 

CONTRAINDICATIONS

Patients contraindicated for permanent SCS therapy are those who:

WARNINGS

Unauthorized Modification.

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.

Pediatric Use.

The safety and effectiveness of spinal cord stimulation has not been established for pediatric use.

Diathermy.

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.

Stimulator Damage.

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.

Postural Changes.

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.

Electromagnetic Interference.

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:

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. 

PRECAUTIONS

Physician training is required.

Medical Devices/Therapies.

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:

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 Therapy.

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.

Post Operative.

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:

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.

Stimulator Location.

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.

Lead Location.

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.

Device Failure.

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.

Operating Temperature.

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.

Component Disposal.

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:

Ensure that the devices are not in use while performing service and maintenance tasks.

Cell Phones.

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.

ADVERSE EFFECTS

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:

In any event, instruct the patient to contact their physician to inform him/her.

CAUTION: U.S. Federal law restricts this device to sale by or on the order of a physician.
