As a result, the site may contain information on pharmaceuticals, medical devices and other products or uses of those products that are not approved in other countries or regions. Product materials. Up to two IPGs, leads, extensions, and burr hole covers may be implanted. Do not bend, kink, or stretch the lead body, sheaths, or other components as this may result in damage to the component and poor function. Ask patients with neurostimulators to shut off the device temporarily while the scan is performed. Lead handling. Using surgical instruments. Explosive or flammable gasses. Control of the patient controller. If the operating field is bloody, wipe gloves, lead, stylet, and sheath before handling the lead. Sources of therapeutic radiation include therapeutic X-rays, cobalt machines, and linear accelerators. Read this section to gather important prescription and safety information. 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. Use fluoroscopy and extreme care when inserting, advancing, or manipulating the guidewire or lead in the epidural space to minimize the risk of a dural tear. Deep brain stimulation complications include, but are not limited to, the following: Undesirable changes in stimulation related to cellular changes in tissue around the electrodes, changes in the electrode position, loose electrical connections, or lead fracture, Loss of therapeutic benefit as a result of change in electrode positions, loose electrical connections, or lead or extension fracture, Initial jolt or tingling during stimulation; jolting or shocking sensations, Lead fracture, migration, or dislodgement, Extension malfunction, fracture, or disconnect, Deep brain stimulation system failure or battery failure within the device, Deep brain stimulation system malfunction or dislodgement, Allergic or rejection response to implanted materials, Persistent pain, tightness, or redness at the incision sites or general pain, General erosion or local skin erosion over the IPG, Persistent pain, tightness, or discomfort around the implanted parts (e.g., along the extension path in the neck), Impaired wound healing (e.g., incision site drainage) or abscess formation, Additional neurosurgical procedure to manage one of the above complications or to replace a malfunctioning component, Stimulation-related complications or other complications, Worsening of motor impairment and Parkinsons disease symptoms including dyskinesia, rigidity, akinesia or bradykinesia, myoclonus, motor fluctuations, abnormal gait or incoordination, ataxia, tremor, and dysphasia, Paresis, asthenia, hemiplegia, or hemiparesis, Sensory disturbance or impairment including neuropathy, neuralgia, sensory deficit, headache, and hearing and visual disturbance, Speech or language impairment including, aphasia, dysphagia, dysarthria, and hypophonia, Cognitive impairment including attention deficit, confusion, disorientation, abnormal thinking, hallucinations, amnesia, delusions, dementia, inability to act or make decisions, psychic akinesia, long term memory impairment, psychiatric disturbances, depression, irritability or fatigue, mania or hypomania, psychosis, aggression, emotional lability, sleep disturbance, anxiety, apathy, drowsiness, alteration of mentation, postural instability and disequilibrium, Cardiac dysfunction (e.g., hypotension, heart rate changes, or syncope), Eye disorder including eye apraxia or blepharospasm, (1) The symbol statement Rx only or only or the statement Caution: Federal law restricts this device to sale by or on the order of a ___, the blank to be filled with the word physician, dentist, veterinarian, or with the descriptive designation of any other practitioner licensed by the law of the State in which the practitioner practices to use or order the use of the device; and. PATIENTS For complete and comprehensive MRI support, parameters, and precautions for all Abbott neuromodulation systems, please see the product manual for each of our devices. ); complications from unusual physiological variations in patients, including foreign body rejection phenomena; paralysis (loss of motor function, inability to move); Possible deep brain stimulation complications. Maximize the distance between the implanted systems; Verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and. Undesirable changes in stimulation, which may be related to cellular changes in tissue around the electrodes, changes in electrode position, loose electrical connections, or lead failure. Exposure of the metal contacts, such as those on the connection end of a lead or extension, to body fluids or saline prior to connection can lead to corrosion. Physicians should also discuss any risks of MRI with patients. Regardless if the device is deactivated, take care to monitor the device for proper function during and after treatment. Detailed information on storage environment is provided in the appendix of this manual. Unilateral or bilateral stimulation of the ventral intermediate nucleus (VIM) of the thalamus for the suppression of disabling upper extremity tremor in adult essential tremor patients whose tremor is not adequately controlled by medications and where the tremor constitutes a significant functional disability. 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. The clinician programmer and patient controller contain a battery and other potentially hazardous materials. The neurostimulation system may interfere with the normal operation of another active implanted device, such as a pacemaker, defibrillator, or another type of neurostimulator. Changes in blood glucose levels in response to any adverse effect Both the Intellis and Vanta SCS devices integrate SureScan MRI technology, providing MRI access anywhere in the body with normal operating mode power settings. Nonadjacent leads and extensions have the possibility of creating a conduit for stray electromagnetic energy that could cause the patient unwanted stimulation. Such restrictions may apply aboard airplanes, near explosives, or in hazardous locations. January 4, 2022 By Sean Whooley. To correct the effects of typical interference, keep wireless communication equipment at least 15 cm (6 in) from the IPG. Security, antitheft, and radiofrequency identification (RFID) devices. Generator disposal. External defibrillators. Scanning under different conditions may cause device malfunction, severe patient injury, or death. Patients should cautiously approach such devices and should request help to bypass them. Patients with implanted Abbott leads should avoid scuba diving in more than 30 m (100 ft) of water or entering hyperbaric chambers above 4.0 atmospheres absolute (ATA) for any length of time, as this may damage the neurostimulation system. If this date has been reached or has been exceeded before the date of implantation, the generator should be charged prior to implantation. Introduction: Spinal cord stimulation is becoming an increasingly used modality for the treatment of chronic pain. All components listed must be implanted unless noted as "optional." This neurostimulation system is indicated for spinal column stimulation via epidural and intraspinal lead access to the dorsal root ganglion as an aid in the management of moderate to severe chronic intractable* pain of the lower limbs in adult patients with complex regional pain syndrome (CRPS) types I and II.**. The Eterna Spinal Cord Stimulation (SCS) System is designed to deliver low-intensity electrical impulses to nerve structures. Instruct patients to use their neurostimulation system only after an authorized clinician has programmed the device and has trained the patient how to control stimulation and safely use the system. The Proclaim XR SCS system can provide relief to . 74372 MAT-2215216 v3.0 | Item approved for U.S. use only. However, advise patients who feel uncomfortable paresthesia during postural changes that they should not operate potentially dangerous equipment such as power tools, automobiles, or other motor vehicles. Set the electrosurgery device to the lowest possible energy setting. NOTE: During intraoperative testing, Surgery mode must be turned off for the neurostimulation system to function correctly. The Proclaim XR implantable pulse generator (IPG) is a novel device designed to supply low-dose BurstDR stimulation in a primary cell battery guaranteed to last 5-10 years with appropriate programming. Expected effect from cessation of therapy, should disease symptoms return unexpectedly. Nonadjacent leads can possibly create a conduit for stray electromagnetic energy that could cause the patient unwanted stimulation. The clinician programmer and patient controller are not waterproof. Magnetic interference with consumer goods or electronic devices that contain magnets, such as mobile phones and smart watches, may unintentionally cause the neurostimulation system to turn on or turn off or affect communication between the device and generator; however, it will not change the prescribed programmed parameters. Skin erosion. Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs (If either occurs, turn off your IPG immediately.). Patients should avoid charging their generator over an incision that has not completely healed. The safety and efficacy of the implantation of greater than four leads have not been evaluated. Do not insert the sheath into the epidural space without the lead or guidewire inserted, as this may cause injury to the dura. Advise patients to keep the patient controller away from children and pets in order to avoid potential damage or other hazards. Securing the anchor. High stimulation outputs and charge density limits. Advise patients to inform their healthcare professional that they should not be exposed to diathermy treatment. Store components and their packaging where they will not come in contact with liquids of any kind. Devices with one-hour recharge per day. Preventing infection. Schu S, Gulve A, ElDabe S, et al. The placement of the leads involves some risk, as with any surgical procedure. Safety and effectiveness has not been established for patients with a neurological disease other than Parkinsons disease or essential tremor, previous surgical ablation procedures, dementia, coagulopathies, or moderate to severe depression; patients under 22 years; implantation in targets other than the STN for Parkinson's disease and the VIM for essential tremor; patients with an active implantable device; patients requiring MRI. During the implant procedure, if an electrosurgery device must be used, take the following actions:. Patients should avoid activities that may put undue stress on the implanted components of the neurostimulation system. If lithotripsy must be used, do not focus the energy near the IPG. Interference with wireless equipment. If the programming of stimulation parameters exceeds the charge density limit of 30 C/cm2, a screen will appear warning you that the charge density is too high. 72784 MAT-2215217 v2.0 | Item approved for U.S. use only. 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. Unwanted changes in stimulation may include a jolting or shocking feeling. A physician can help determine if a patient is eligible to receive an MRI scan by following the requirements provided by Abbott Medical. Care and handling of components. This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. No use of any Abbott trademark, trade name, or trade dress in this site may be made without the prior written authorization of Abbott, except to identify the product or services of the company. 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. Conscious sedation. However, some patients may experience a decrease or increase in the perceived level of stimulation. Consumer goods and electronic devices. Security, antitheft, and radiofrequency identification (RFID) devices. External defibrillators. Nerve damage may result from traumatic or surgical nerve injury. Patients should not dive below 30 m (100 ft) of water or enter hyperbaric chambers above 4.0 atmospheres absolute (ATA). Manipulation may cause device inversion, inhibiting the ability to use the magnet to start or stop stimulation. Postoperatively, actively monitor patients for new or worsening symptoms of depression, suicidal thoughts or behaviors, or changes in mood or impulse control. The safety and effectiveness of neurostimulation for pediatric use have not been established. For more information about MR Conditional deep brain stimulation (DBS) components and systems, including equipment settings, scanning procedures, and a complete listing of conditionally approved components, refer to the MRI procedures clinician's manual for DBS systems(available online atmedical.abbott/manuals). The force of the instruments may damage the lead or stylet. The IPG should be explanted before cremation because the IPG could explode. If use of electrocautery is necessary, place the neurostimulator in Surgery mode using the clinician programmer app or the patient controller app before using an electrosurgery device. 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. Electromagnetic interference (EMI). Patients should be advised to keep their mobile phones and smart watches at least 15 cm (6 in.) The website that you have requested also may not be optimized for your screen size. IPGs contain batteries as well as other potentially hazardous materials. The abrupt cessation of stimulation for any reason will probably cause disease symptoms to return. 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. Component manipulation by patients. 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. Neurostimulation should not be used on patients who are poor surgical risks or patients with multiple illnesses or active general infections. Jude, Medtronic).Most of the early models of these devices were considered MR Unsafe primarily due to the theoretical risk of spinal cord injury from heating of the the electrode tip by RF-induced currents (the so-called antenna effect). Back pain. Patients should be instructed to avoid bending, twisting, stretching, and lifting objects over 2 kg (5 lb) for at least six weeks after implantation. The following additional considerations should be made for patients with diabetes: A pre-operative risk assessment should be performed for patients with diabetes who are at high risk for ischemic heart disease, those with autonomic neuropathy or renal failure, and patients with a Hemoglobin A1C (HbA1c) 8% (64 mmol/mol). Important note: For CT procedures that require scanning over the medical device continuously for more than a few seconds, as with CT perfusion or interventional exams, attending staff should be ready to take emergency measures to treat adverse reactions if they occur. Surgical complications include, but are not limited to, the following: intracranial hemorrhage (which can lead to stroke, paralysis, or death); cerebrospinal fluid leakage or cerebrospinal fluid abnormality; persistent pain at surgery site or IPG site; brachial plexus injury (nerves to chest, shoulder and arm); postoperative pain, stress, or discomfort; hemiparesis (muscular weakness or partial paralysis on one side of body); ballism or hemiballism (uncontrollable movements on both or only one side of the body); confusiontransient, nocturnal or ongoing; cognitive impairment, including delirium, dementia, disorientation, psychosis and speech difficulties; pulmonary embolism (sudden blood vessel obstruction); aborted procedures (air embolism, unable to find target, surgical complication, etc. For more information about setting the magnet mode, refer to the clinician programmer manual or contact Technical Support.
