IS IT SAFE TO PASS THROUGH METAL DETECTORS?

Some metal detectors and anti-theft devices may affect your stimulation therapy. Before you go through these kinds of devices, show your device ID card to security personnel and ask how best to proceed.

If you have to go through a metal detector or anti-theft device, turn off your neurostimulator and proceed carefully, moving quickly through the device. Once you’ve passed through the detector or device, be sure to check the status of your device.

Learn more about electromagnetic interference (EMI).

DOES HAVING A DBS SYSTEM MEAN I DON’T HAVE TO TAKE MEDICATION ANYMORE?

DBS therapy can be used in combination with medication to achieve the best results for your condition. Sometimes, however, medication use can be decreased, potentially reducing medication-related side effects. We recommend that you talk to your doctor about what’s right for you.

HOW LONG AFTER I GET THE DBS SYSTEM WILL MY SYMPTOMS IMPROVE?

Some people’s symptoms improve immediately after their surgery. For others, improvement is a process, which may involve working with your doctor to find the best combination of stimulation and medication as you recover from surgery. This process can sometimes take several months.

WILL DBS THERAPY PREVENT MY MOVEMENT DISORDER FROM GETTING WORSE?

The goal of DBS therapy is to improve your quality of life and provide an extended period during which your symptoms can be controlled. It may also reduce the amount of medication you need to take, potentially reducing medication-related side effects. However, DBS therapy is not a cure for Parkinson’s disease or essential tremor, and it is unlikely that it will completely get rid of your symptoms or stop them from getting worse.

WILL I BE ABLE TO “FEEL” THE STIMULATION?

Most people do not feel the stimulation once they find the right settings for their treatment. You may feel mild and painless sensations during a programming session, but these sensations are typically short-lived and disappear once adjustments are made.

HOW LONG WILL MY DBS DEVICE LAST?

The St. Jude Medical Infinity™ DBS System is recharge-free, meaning you won’t have to manage the battery. Your doctor can check the battery’s charge during programming sessions using his or her Apple‡ iPad mini‡ mobile digital device. He or she will keep you updated as needed.

See more information about your device’s battery.

WHAT ARE THE RISKS?

Talk to your doctor about complications related to the implant procedure and/or your DBS device. Complications are rare.

  • Serious complications such as coma, bleeding inside the brain, paralysis, seizures and infection, may result; some may be fatal.
  • Once implanted, the area around the system may become infected, parts may wear through your skin, and the lead or lead/extension connector may move. Any of these situations may require additional surgery or cause your symptoms to return.
  • While most complications will have no after-effects, some people may experience lasting, stroke-like symptoms, such as weakness, numbness, problems with vision or slurred speech.

In the event that side effects are intolerable or you are not satisfied with the therapy, the DBS system can be turned off or surgically removed.

IMPORTANT SAFETY INFORMATION

Deep Brain Stimulation

Prescription and Safety Information

Read this section to gather important prescription and safety information.

Intended Use

This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. The system is intended to be used with leads and associated extensions that are compatible with the system.

Indications for Use

This neurostimulation system is indicated for unilateral or bilateral stimulation of the thalamus, internal globus pallidus (GPi), or subthalamic nucleus (STN) in patients with levodopa-responsive Parkinson’s disease.

Contraindications

Implantation of this neurostimulation system is contraindicated for the following:

  • Patients for whom test stimulation is unsuccessful.
  • Patients who are unable to properly operate the system.

 

The following procedures are contraindicated for patients that have been implanted with this device:

Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and can cause tissue damage at the location of the implanted electrodes, resulting in a severe injury or death. Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off. All patients are advised to inform their healthcare professional that they should not be exposed to diathermy treatment.

Magnetic resonance imaging (MRI). Do not use a full body radiofrequency (RF) coil or other extremity coils on patients implanted with a neurostimulation system. Because energy from MRI can be transferred through the implanted system, the potential for heat generation at the location of the electrodes exists. This isolated temperature rise may cause tissue damage at the location of the implanted electrodes, possibly resulting in severe injury or death. Injury can occur during MRI treatment whether the neurostimulation system is turned on or off. All patients are advised to inform their healthcare professional that they should not be exposed to MRI.

Warnings

The following warnings apply to these components.

Poor surgical risks. Neurostimulation should not be used on patients who are poor surgical risks or patients with multiple illnesses or active general infections.

Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.

During implant procedures, if electrosurgery devices must be used, take the following actions:

  • Use bipolar electrosurgery only.
  • Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
  • Keep the current paths from the electrosurgery device as far from the neurostimulation system as possible.
  • Set the electrosurgery device to the lowest possible energy setting.
  • Confirm that the neurostimulation system is functioning correctly during the implant procedure and before closing the neurostimulator pocket.

Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system, (1) maximize the distance between the implanted systems; (2) verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and (3) avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system.

Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation. Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation. Patients who are implanted with nonadjacent multiple leads and patients who are sensitive to low stimulation thresholds may experience a momentary increase in their perceived stimulation, which some patients have described as uncomfortable or jolting. Patients should cautiously approach such devices and should request help to bypass them. If they must go through a gate or doorway containing this type of device, patients should turn off their IPG and proceed with caution, being sure to move through the device quickly.

Motor vehicles, machinery, and equipment. Patients should not operate motor vehicles, potentially dangerous machinery, or power tools or engage in any activity that would be potentially unsafe if their symptoms were to return unexpectedly.

Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.

Case damage. Do not handle the IPG if the case is pierced or ruptured because severe burns could result from exposure to battery chemicals.

Cremation. The IPG should be explanted before cremation because the IPG could explode. Return the explanted IPG to Abbott Medical.

IPG disposal. Return all explanted IPGs to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.

Charge density. A risk of tissue damage exists with stimulation parameter settings of high amplitudes and wide pulse widths. Higher amplitude and pulse width settings required to achieve therapy may indicate a system problem or suboptimal lead placement. Parameter values exceeding the charge density limit of 30 μC/cm2 should only be programmed with due consideration of the warnings concerning charge densities. Charge density can be reduced by lowering the stimulation amplitude or pulse width.

Low frequencies. Stimulation frequencies less than 30 Hz may be programmed; however, these frequencies may cause tremor to be driven (i.e., occur at the same frequency as the programmed frequency). For this reason, programming at lower frequencies is not recommended.

Precautions

The following precautions apply to this neurostimulation system.         

General Precautions

Surgeon training. Implanting physicians should be experienced in stereotactic and functional neurosurgery.

Clinician training. Clinicians should be familiar with deep brain stimulation therapy and be experienced in the diagnosis and treatment of the indication for which the deep brain stimulation components are being used.

Patient selection. Select patients appropriately for deep brain stimulation. The patient should be able and willing to use the patient controller and correctly interpret the icons and messages that appear on the screen.  

Infection. Follow proper infection control procedures. Infections may require that the device be explanted.

Electromagnetic interference (EMI). Some equipment in home, work, medical, and public environments can generate EMI that is strong enough to interfere with the operation of a neurostimulation system or damage system components. Patients should avoid getting too close to these types of EMI sources, which include the following examples: commercial electrical equipment (such as arc welders and induction furnaces), communication equipment (such as microwave transmitters and high-power amateur transmitters), high-voltage power lines, radiofrequency identification (RFID) devices, and some medical procedures (such as therapeutic radiation and electromagnetic lithotripsy).

Sterilization and Storage

Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.

Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind. Detailed information on storage environment is provided in the appendix of this manual.

Handling and Implantation

Expiration date. An expiration date (or “use-before” date) is printed on the packaging. Do not use the system if the use-before date has expired.

Care and handling of components. Use extreme care when handling system components prior to implantation. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.

Package or component damage. Do not implant a device if the sterile package or components show signs of damage, if the sterile seal is ruptured, or if contamination is suspected for any reason. Return any suspect components to Abbott Medical for evaluation.

System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite.

Device modification. The equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.

Hospital and Medical Environments

Electrical medical treatment. In the case that a medical treatment is administered where an electrical current is passed through the body from an external source, first deactivate the IPG by setting all electrodes to off, turning stimulation off, and setting amplitude to zero. Regardless if the device is deactivated, take care to monitor the device for proper function during and after treatment.

High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotriptor, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.

Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.

External defibrillators. The safety of discharge of an external defibrillator on patients with implanted neurostimulation systems has not been established.

Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.

Psychotherapeutic procedures. The safety of psychotherapeutic procedures, such as electroshock therapy and transcranial magnetic stimulation, which use equipment that generates electromagnetic interference, has not been established.

Electrocardiograms. Neurostimulation pulses may be detected by electrocardiograms.

Home and Occupational Environments

Patient activities and environmental precautions. Patients should take reasonable care to avoid devices that generate strong EMI, which may cause the neurostimulation system to unintentionally turn on or off. Patients should also avoid any activities that would be potentially unsafe if their symptoms were to return unexpectedly.

Mobile phones. The effect of mobile phones on deep brain stimulation is unknown. Patients should be advised to avoid carrying mobile phones in their shirt pocket or otherwise placing them directly over the deep brain stimulation system components. If interference occurs, try holding the phone to the other ear or turning off the phone.

Household appliances. Household appliances that contain magnets (e.g., refrigerators, freezers, inductive cooktops, stereo speakers, mobile telephones, cordless telephones, standard wired telephones, AM/FM radios, and some power tools) may unintentionally cause the neurostimulation system to turn on or turn off.

Therapeutic magnets. Patients should be advised to not use therapeutic magnets. Therapeutic magnets (e.g., magnets used in pillows, mattress pads, back belts, knee braces, wrist bands, and insoles) may unintentionally cause the neurostimulation system to turn on or off.  

Radiofrequency sources. Devices that contain permanent magnets (e.g., mobile telephones, cordless telephones, standard wired telephones, and AM/FM radios) may unintentionally cause the IPG to turn on or off.
