Types of Pain © Medtronic, Inc. 2008Let’s begin by looking at different types of pain. © Medtronic, Inc. 2008
Types of Neuropathic PainDirect nerve root injury: radiculopathy Battered root syndrome Perineural fibrosis Intrafascicular fibrosis Adhesive arachnoiditis Peripheral deafferentation Phantom limb pain Sympathetic-mediated pain syndrome Herpetic neuralgia Diabetic polyneuropathy Central deafferentation-thalamic stroke Here are some examples of neuropathic pain. © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg
Types of Nociceptive PainMechanical low back pain Discogenic pain Joint pain Facet joint Sacroiliac joint Pseudoarthrosis Osteoporosis Musculoskeletal trauma Here are some examples of nociceptive pain. © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg
Combined Nociceptive and Neuropathic PainFailed Back Surgery Syndrome (FBSS)* Idiopathic chronic pain syndrome Cancer pain *Also referred to as “post-surgical chronic back pain” Some pain exhibits characteristics of both nociceptive and neuropathic pain. © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg
Chronic Pain ConditionsPost-surgical chronic back pain or failed back Radicular pain syndrome or radiculopathies resulting in pain secondary to failed back or herniated disk Postlaminectomy pain Multiple back operations Unsuccessful disk surgery Degenerative disk disease, herniated disk pain refractory to conservative and surgical interventions Peripheral causalgia Epidural fibrosis Arachnoiditis or lumbar adhesive arachnoiditis Complex regional pain syndrome, reflex sympathetic dystrophy or causalgia [Speak to the slide.] © Medtronic, Inc. 2008
Device therapies are now considered earlier in the treatment continuumPain Treatment Ladder Device therapies are now considered earlier in the treatment continuum The Stamatos version of the Pain Treatment Ladder proposes focusing on the area causing the pain, rather than treating the whole body. In contrast to the traditional treatment ladder approach, interventional therapies, corrective surgery, and neurostimulation are placed before long-term opioid therapy. This allows targeting of medication or therapy to the specific area of pain before a more general pain treatment approach is applied. © Medtronic, Inc. 2008 Stamatos JM, et al. Live Your Life Pain Free, October Based on the interventional pain management experience of Dr. John Stamatos
Introduction to Medtronic NeurostimulationNow we’ll discuss implantable pain therapies including neurostimulation—also known as spinal cord stimulation—and intrathecal drug delivery. Both therapies have been proven to be effective in managing pain for those patients experiencing moderate to severe chronic pain that cannot be alleviated using other methods.1,2 We’ll begin with neurostimulation. Burchiel K, Anderson V, et al. Prospective, Multicenter Study of Spinal Cord Stimulation for the Relief of Chronic Back and Extremity Pain. Spine. 1996; 21: Winkelmuller M, Winkelmuller W. Long-term Effects of Continuous Intrathecal Opioid Treatment in Chronic Pain of Non-malignant Etiology. J Neurosurg. 1996; 35: [Note: page numbers appear this way in Practicum presentation] © Medtronic, Inc. 2008
Neurostimulation TherapyDelivers small electrical signals to the epidural space Inhibits pain signals before they reach the brain and replaces them with a tingling sensation that covers the specific areas where pain was felt Indicated for treatment of chronic, intractable pain of the trunk and/or limbs, including unilateral or bilateral pain The neurostimulator system consists of: A small electronic system called the neurostimulator, which creates the impulses to block the pain signals from reaching the brain A lead through which electrical stimulation is delivered to the spinal cord An extension that connects the lead to the neurostimulator © Medtronic, Inc. 2008
Benefits of NeurostimulationAn effective method of pain control for many patients Reduces or eliminates pain medications Non-destructive and less invasive than surgical alternatives Reversible – can be discontinued or surgically removed Systems reprogrammable without surgery Trial helps assess patient response Patient control within physician-set limits [Speak to the slide. Stress that implantation of a neurostimulator system is a minimally invasive surgery. The system can be removed at any time. The trial allows the patient to try the system prior to implant.] © Medtronic, Inc. 2008 Kumar K, Nath RK, Toth C. Deep Brain Stimulation for Intractable Pain: A 15-year experience. Neurosurgery. 1997
Neurostimulation TrialPain Therapy Trial provides an opportunity to measure the effectiveness of neurostimulation without making a long-term commitment Gauge patient response Provide an adjustment period Explore therapy parameters Improve therapy cost-effectiveness The goal is at least a 50% reduction in pain without intolerable side effects Patient-specific goals may include less pain reduction but improved quality of life Candidates for neurostimulation undergo a trial to help predict the success of this therapy. During the trial, patients should experience at least a 50% reduction in pain, without intolerable side effects. © Medtronic, Inc. 2008 Kumar K, et al. Neurosurgery. 2006;58:
Some Risks of NeurostimulationLead migration resulting in loss of pain relief Intermittent or uncomfortable stimulation Stimulation in the wrong location Neurological damage during procedure Risk of infection at implantation [Speak to the slide.] For complete list of risks/complications, refer to product package insert © Medtronic, Inc. 2008 North R, Kidd D, Zahurak M, et al. Neurosurgery. 1993;32:
Introduction to Medtronic Intrathecal Drug Delivery (IDD)Now we’ll focus on Intrathecal Drug Delivery. © Medtronic, Inc. 2008
Intrathecal Drug Delivery (IDD) TherapyIDD therapy involves the delivery of pain medicine in the intrathecal space The pump is connected to a thin, flexible catheter; both are implanted under the skin Smaller doses of medication are needed for effective pain relief because drug is delivered directly to the pain receptors Intrathecal drug delivery (IDD) uses a drug delivery system to place medication directly to the intrathecal space of the spine. IDD consists of: A round pump device that stores and delivers pain medication A catheter that is connected to the pump and inserted into the spine © Medtronic, Inc. 2008
Synchromed® II Drug Infusion System IndicationsChronic intrathecal infusion of preservative-free morphine sulfate sterile solution in the treatment of chronic intractable pain Also indicated for chronic intrathecal infusion of Lioresal® Intrathecal (baclofen injection) for severe spasticity, chronic epidural infusion of preservative-free morphine sulfate sterile solution in the treatment of chronic intractable pain, and chronic intrathecal infusion of preservative-free ziconotide sterile solution for the management of severe chronic pain When being used for chronic pain, the pump can be filled with: Preservative-free morphine Ziconotide sterile solution © Medtronic, Inc. 2008 Lioresal® is a registered trademark of Novartis Pharmaceuticals, Inc.
Approximate Equivalent Daily Doses of MorphineRoute of Administration Relative Potency (mg)* Oral Intravenous Epidural Intrathecal 300 100 20 1 Intrathecal Drug Delivery can provide significant pain control with a small fraction of the dose (as little as 1/300th) that would be required with oral medications. This helps minimize side effects. *Relative approximations based on clinical observations © Medtronic, Inc. 2008 Lamer TJ: Mayo Clin Proc. May 1994;69(5):
Benefits of IDD TherapyPain relief for patients who have not received adequate relief with conventional therapies Reduction in adverse effects from oral opioids such as nausea, vomiting, sedation, and constipation Decreased or elimination of oral analgesics Increased ability to perform activities of daily living Patient control within physician-set limits May be effective for patients who do not experience relief from neurostimulation therapy [Speak to the slide. Emphasize that because the drug is delivered directly to the intrathecal space, IDD offers significant pain control with lower doses of medication.] © Medtronic, Inc. 2008 Lamer TJ: Mayo Clin Proc. May 1994;69(5): ; Paice JA, et al: J Pain Symptom Manage.1996;11(2):71-80.
IDD Trial The purpose of the trial is to assess the efficacy and side effects of intrathecal morphine Trialing methods include Continuous epidural Continuous intrathecal Bolus epidural Bolus intrathecal Patients who report at least 50% reduction in pain may be candidates for long-term therapy Candidates for IDD undergo a trial procedure to predict success with an implanted pump. During the trial, patients should experience at least a 50% reduction in pain, without intolerable side effects to the test drug, to be considered for the therapy. © Medtronic, Inc. 2008
IDD Therapy Risks Programming error Drug concentration errorSurgical complications, such as infection Catheter could become dislodged or blocked The pump could stop working Other side effects may occur [Speak to the slide.] For complete list of risks/complications, refer to product package insert © Medtronic, Inc. 2008 Onofrio BM, Yaksh TL.

Patient Selection © Medtronic, Inc. 2008
Indications for Neurostimulation and Intrathecal Drug Delivery TherapyNeurostimulation and Intrathecal Drug Delivery are indicated for a variety of chronic pain conditions. A number of conditions can be treated with neurostimulation or intrathecal drug delivery. As a result, if a patient does not respond well to neurostimulation, IDD can be applied. © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg 362. Refer to full prescribing information for Medtronic Neurostimulation Systems and Synchromed® II and Isomed® Drug Infusion Systems
Patient Selection ConsiderationsPatients who have neuropathic pain in a concordant anatomic distribution respond best to neurostimulation (NS) therapy Patients who have nociceptive pain in a concordant distribution respond best to Intrathecal Drug Delivery (IDD) Patients who do not respond well to NS may be candidates for IDD therapy [Speak to the slide. Stress the final bullet point.] © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg 362.
Patient Selection ChecklistFailure of oral/transdermal opiate use or undesirable side effects More conservative therapies have failed An observable pathology exists that is concordant with the pain complaint Further surgical intervention is not indicated No serious untreated drug habituation exists Psychological evaluation and clearance for implantation has been obtained No contraindications to implantation exist Appropriate patients will have experienced inadequate pain relief and/or intolerable side effects from more conservative therapies. A psychological evaluation should reveal a patient’s true expectations of the therapy. After fulfilling the criteria listed above, the patient proceeds to a trial. This test helps predict success of the therapy. Refer Patient for a Pain Therapy Trial © Medtronic, Inc. 2008 Cole AJ. In Low Back Pain Handbook, 2nd ed. 2003; pg 362.

Role of Interventional Pain Specialist© Medtronic, Inc. 2008
Practice Management CollaborationThe roles of the referring physician and pain specialist are interdependent when treating chronic pain patients. Together, you play an important role in accessing effective pain treatment options. © Medtronic, Inc. 2008
Interventional Pain Specialist Pain Management ApproachRecognizes unique benefits of technological advances and interventions Communicates with all concerned parties to ensure best treatment possible Develops follow-up plan once pain successfully treated Collaborates with referring physician when treatment overlaps with general health care Follows up with referring physician once pain is controlled [Speaker should discuss his/her approach to managing pain patients after referral.] © Medtronic, Inc. 2008
Interventional Pain Specialist Referral CriteriaMultiple symptoms or pain sources Conservative therapies not working Patient’s functional status deteriorated Uncomfortable prescribing or monitoring opioids It is important to understand the need to refer a chronic pain patient early in the process. Patients often are referred to a pain clinic after too many ineffective therapies have been applied and failed. Early referral will allow the pain specialist to provide a comprehensive formulation of the problem and a quick reversal of the situation when possible. Being able to identify circumstances under which a subspecialty referral is needed is key to ensuring a patient gets the right treatment. © Medtronic, Inc. 2008
Device Therapy Referral Interventional Pain Specialist RoleConduct a thorough patient history and physical exam Develop an interventional pain treatment plan Conduct a Medtronic Pain Therapy trial Perform the Medtronic Pain Therapy implantation or refer after the trial Develop a follow-up plan with the patient [Speak to the slide. Stress the collaborative relationship that should exist between the physicians.] © Medtronic, Inc. 2008
Summary With today’s treatments, patients should not have to wait for effective pain relief By partnering, we can help patients find the right pain treatment Together we can improve the quality of life for chronic pain patients Our decisions may change the course of a patient’s life Working as a team, we are able to treat all aspects that factor into the patients’ pain experience: health, injury, emotional, family, community and psychosocial. Together we can improve the quality of life for chronic pain patients and our decisions may change the course of their lives. © Medtronic, Inc. 2008
Case Study Male, 45, office manager, no major psychosocial issuesOne spine surgery to treat herniated disc Referred from primary care physician to address axial back pain and secondary radicular pain that persists six months following anatomically corrective surgery Average back pain score (VAS) of 80/100 with diminished functional capacity Relief from physical rehabilitation therapy was not satisfactory Unsuccessfully treated with neuropathic pain agents and two systemic opioids, patient experienced extreme sedation and constipation Treated with nerve block series but relief was temporary Our final discussion point is the case study outlined above. © Medtronic, Inc. 2008
SynchroMed® Infusion System Brief SummaryIndications: US: Chronic intraspinal (epidural and intrathecal) infusion of preservative-free morphine sulfate sterile solution in the treatment of chronic intractable pain, chronic intrathecal infusion of preservative-free ziconotide sterile solution for the management of severe chronic pain, and chronic intrathecal infusion of Lioresal® Intrathecal (baclofen injection) for the management of severe spasticity; chronic intravascular infusion of floxuridine (FUDR) or methotrexate for the treatment of primary or metastatic cancer. Outside of US: Chronic infusion of drugs or fluids tested as compatible and listed in the product labeling. Contraindications: When infection is present; when the pump cannot be implanted 2.5 cm or less from the surface of the skin; when body size is not sufficient to accept pump bulk and weight; when contraindications exist relating to the drug; drugs with preservatives. Do not use the Personal Therapy Manager accessory to administer opioid to opioid-naïve patients or to administer ziconotide. Warnings: Comply with all product instructions for initial preparation and filling, implantation, programming, refilling, and injecting into the catheter access port (CAP) of the pump. Failure to comply with all instructions can lead to technical errors or improper use of implanted infusion pumps and result in additional surgical procedures, a return of underlying symptoms, or a clinically significant or fatal drug under- or overdose. Refer to the appropriate drug labeling for specific under- or overdose symptoms and methods of management. Avoid using short wave (RF) diathermy within 30 cm of the pump or catheter. Diathermy may produce significant temperature rises in the area of the pump and continue to heat the tissue in a localized area. If overheated, the pump may over infuse the drug, potentially causing a drug overdose. Effects of other types of diathermy (microwave, ultrasonic, etc.) on the pump are unknown. An inflammatory mass that can result in serious neurological impairment, including paralysis, may occur at the tip of the implanted catheter. Clinicians should monitor patients on intraspinal therapy carefully for any new neurological signs or symptoms. For intraspinal therapy, use only preservative-free sterile solution indicated for intraspinal use. Use only Medtronic components indicated for use with this system. Failure to firmly secure connections can allow drug or cerebrospinal fluid (CSF) leakage into tissue and result in tissue damage or inadequate therapy. A postoperative priming bolus should not be programmed if the pump is a replacement and the catheter has not been aspirated. © Medtronic, Inc. 2008
SynchroMed® Infusion System Brief Summary continuedRefer to appropriate drug labeling for indications, contraindications, warnings, precautions, dosage and administration information, and screening procedures. Physicians must be familiar with the drug stability information in the technical manual and must understand the dose relationship to drug concentration and pump flow rate before prescribing pump infusion. Implantation and ongoing system management must be performed by individuals trained in the operation and handling of the infusion system. Inform patients of the signs and symptoms of drug under- or overdose, appropriate drug warnings and precautions regarding drug interactions, potential side effects, and signs and symptoms that require medical attention. Instruct patients to notify their clinician of travel plans, to return for refills at prescribed times, avoid activities such as strenuous exercise or contact sports that jar, impact, twist, or stretch the body, to always carry their Medtronic device identification card, to avoid manipulating the pump through the skin, and to notify healthcare professionals of the implanted pump before medical tests/procedures. Patients must consult their physician before engaging in activities involving pressure or temperature changes (e.g., scuba diving, saunas, hot tubs, hyperbaric chambers, flights, skydiving, etc.) Inform patients that pump has an Elective Replacement Indicator (ERI) that sounds when the pump is nearing its end of service. When the alarm sounds, patients must contact their doctor to schedule pump replacement. Precautions:The pump is ethylene oxide sterilized. Do not use if the product or package is damaged, the sterile seal is broken, or the “Use By” date has expired. Do not reuse or resterilize the pump; it is intended for “single use only.” Do not expose the pump to temperatures above 43°C or below 5°C. Consider use of peri- and post-operative antibiotics for pump implantation, for any subsequent surgical procedure, or if infection is present. For patients prone to CSF leaks, clinicians should consider special procedures, such as a blood patch. Follow instructions for emptying and filling the pump during a replacement or revisions that require removal of the pump from the pocket. Explant the pump postmortem if incineration is planned (to avoid explosion), or if local environmental regulations mandate removal. Return explanted devices to Medtronic for analysis and safe disposal. Do not implant a pump dropped onto a hard surface or showing signs of damage. Implant the pump less than 2.5 cm from the surface of the skin. Ensure pump ports will be easy to access after implant, that the catheter is not kinked and secured well away from pump ports before suturing. Keep the implant site clean, dry, and protected from pressure or irritation. If therapy is discontinued for an extended period of time, fill the reservoir with preservative-free saline in intraspinal applications or appropriate heparinized solution (if not contraindicated) in vascular applications. The magnetic field or telemetry signals produced by the programmer may cause sensing problems and inappropriate device responses with an implantable pacemaker and/or defibrillator. Electromagnetic interference (EMI) is an energy field generated by equipment found in the home, work, medical, or public environments. Most EMI normally encountered will not affect the operation of the pump. Exceptions include: injury resulting from heating of the pump which can damage surrounding tissue (diathermy, MRI), system damage which can require surgical replacement or result in loss/change in symptom control (defibrillation, electrocautery, high-output ultrasonics, radiation therapy), and operational changes to the pump causing the motor to stop, loss of therapy, return of underlying symptoms, and require confirmation of pump function (diathermy, high magnetic field devices, hyperbaric/hypobaric conditions, magnetic resonance imaging (MRI)). MRI will temporarily stop the pump motor’s rotor due to the magnetic field of the MRI scanner and suspend drug infusion during MRI exposure which will cause the pump alarm to sound. The pump should resume normal operation upon termination of MRI exposure. Prior to MRI, the physician should determine if the patient can safely be deprived of drug delivery. If not, alternative delivery methods for the drug can be utilized during the MRI scan. Prior to scheduling an MRI scan and upon its completion, pump status should be confirmed. © Medtronic, Inc. 2008
SynchroMed® Infusion System Brief Summary continuedAdverse Events: Include, but are not limited to, cessation of therapy due to end of device service life or component failure, change in flow performance due to component failure, inability to program the device due to programmer failure, CAP component failure; inaccessible refill port due to inverted pump, pocket seroma, hematoma, erosion, infection, post-lumbar puncture (spinal headache), CSF leak, radiculitis, arachnoiditis, bleeding, spinal cord damage, meningitis (intrathecal applications), anesthesia complications, damage to the pump, catheter and catheter access system due to improper handling and filling before, during, or after implantation; change in catheter performance due to catheter kinking, disconnection, leakage, breakage, occlusion, dislodgement, migration, or catheter fibrosis; body rejection phenomena, surgical replacement of pump or catheter due to complications; local and systemic drug toxicity and related side effects, complications due to use of unapproved drugs and/or not using drugs in accordance with drug labeling, or inflammatory mass at the tip of the catheter. !USA Rx Only © Medtronic, Inc. 2008
