Deep Brain Stimulation (DBS) is a brain surgery (in which nerves are stimulated with electrodes) performed to improve a patient's quality of life. The procedure is not a cure, but it can significantly improve otherwise debilitating symptoms caused by certain neurological disorders. DBS is most commonly used to treat movement disorders including Parkinson's disease, Dystonia, and Essential Tremor. It may also be appropriate in selected cases of other conditions including Tourette's syndrome and Chronic Cluster Headache. Products used within a procedure may include but not limited to: — electrodes, — extensions, — implantable pulse generator, — patient programmer, — tunneller, — recharge unit, — external battery. Spinal cord stimulation is reserved for patients who have severe chronic pain that is limiting their daily life and who have already tried all reasonable, more conservative therapies, such as painkillers and physiotherapy. Spinal cord stimulation requires a minor surgical procedure under x-ray control in which a lead (medical wire) is precisely sited within the epidural space of the spine – for percutaneous wire insertion. If a surgical paddle electrode is inserted then a small window is created in the bone and ligament of the spine to place the electrode. In both cases, the lead is then connected under the skin to a battery device which is surgically sited in the buttock or abdominal wall. The battery powers the electrical stimulation of the lead in the spine. Once the system is set-up, it is controlled by the patient using a handheld controller. Many factors, including site and type of pain, are considered in determining which type of system to use. Products used within a procedure may include but not limited to: • Implantable pulse generator • Electrodes • Extension • Anchors • Patient programmer • External battery • Tunneller • Recharge unit • Receiver Sacral nerve stimulation is an implanted system which can help improve bladder function by sending electrical signals to the nerves that control your bladder. It is a treatment that is used for the overactive bladder, urgency and incontinence, and in some cases retention of urine. Products used within a procedure may include but not limited to: • Electrodes • Extensions • Implantable pulse generator • Patient programmer • Receiver • Anchors • External battery Vagus nerve stimulation or vagal nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an adjunctive treatment for certain types of intractable epilepsy, treatment-resistant depression and for treatment-resistant primary headache disorders. Products used within a procedure may include but not limited to: • Electrodes • Extensions • Implantable pulse generator • Non implantable nerve stimulator • Patient programmer • Conductive gel • Recharge unit The target is a branch nerve of the spinal cord called the Dorsal Root Ganglion (DRG). The DRG has been a target for physicians for pain relief for many years. The DRG can regulate pain signals before they enter the spinal cord and travel to the brain. DRG is accessed via a needle placed in the spinal epidural space using a curved introducer the leads are routed to lie above the DRG. Products used within a procedure may include but not limited to: • Electrodes • Extension • Implantable pulse generator • Patient programmer • External trial battery • Recharge Unit • Receiver • Anchors Peripheral Nerve Stimulation (PNS) is a surgical approach to treat chronic pain in a small area of your body for patients with Neuropathy in the peripheral nervous system. Peripheral Nerve Stimulation involves surgery that places a lead (a wire-like electrode) next to peripheral nerves to control pain. The lead delivers rapid electrical pulses that are felt as a mild/pleasant tingling sensation called paraesthesia. The goal of this process is to reduce pain and reduce your medication requirements. Products used within a procedure may include but not limited to: • Electrodes • Extensions • Implantable pulse generator • Patient programmer • Non implantable nerve stimulator • Nerve stimulating pen • Receiver • Anchors • External trial battery A number of painful conditions can be treated using occipital nerve stimulation. Patients with the following conditions who have failed all standard medical therapies may benefit: Cluster headaches; Chronic Migraine; Occipital neuralgia; Whiplash-related headaches; other neck-related or ‘cervicogenic’ headaches; Nerve injuries (from trauma or previous surgery). Products used within a procedure may include but not limited to: • Electrodes • Implantable pulse generator • Patient programmer • Extension • Recharge unit • Anchors Radiofrequency (RF) ablation is an effective means of reducing pain in selected patients on the basis of controlled diagnostic blocks. The pain management RF transmits a small radiofrequency current through the insulated needle to deactivate the nerve that is responsible for sending the pain signal to the brain. Products used within a procedure may include but not limited to: • Generator • Electrodes • Grounding plate • Needle The Phrenic nerve stimulator is a system for long-term artificial ventilation in patients who suffer from respiratory muscle paralysis (RMP) or central alveolar hypoventilation (CAH). Instead of natural activation of ever changing firing axons of phrenic nerves in a randomised fashion, four compartments of the phrenic nerve is stimulated sequentially by means of four pole electrode during each inspiration. The four pole electrode(s) is surgically implanted around the phrenic nerve(s), leading to implant stimulator usually implanted in the chest wall. An external stimulus controller sends radio frequency signals to the implant stimulator by energy transfer coil which is worn over the implant stimulator. Products used within a procedure may include but not limited to: • Electrode • Extension lead • Implantable nerve stimulator Intrathecal drug delivery, or “pain pump”, is a method of giving medication directly to your spinal cord. The system uses a pump that is surgically placed under the skin of your abdomen and delivers medication through a catheter to the area around your spinal cord. Products used within a procedure may include but not limited to: • Infusion pump • Catheter access port kit • Catheter passer • Catheter • Anchor • Tunneller Sphenopalatine Ganglion Stimulation (SPGS) is a therapy used to treat chronic headache disorders. Patients who have failed medical management for their condition may benefit from this therapy. SPGS involves the insertion of a microstimulator with integrated stimulating electrodes adjacent to the SPG via a minimally invasive intra-oral procedure. A number of specialist surgical tools are required to aid in the positioning of the microstimulator. The therapy is activated and controlled by the patient via an external wireless remote control. Products used within a procedure may include but not limited to: • Implantable micro stimulator with integrated stimulating electrodes • Surgical access tool • Surgical positioning tool • Patient remote controller • Clinician programmer • Wireless data link cable Dorsal Ramus Medial Branch nerve stimulation is reserved for patients who have debilitating chronic low back pain, no indications for surgery and who have already tried all reasonable, more conservative therapies, such as back pain medication and physiotherapy. The stimulation target is the medial branch of the L2 dorsal ramus nerve which is situated outside of the spinal canal. The medial branch is a “mixed” nerve. It transmits pain signals from the spine joints to the brain, but at the same time it controls the spine stabilising muscles in the lower back. The medial branch is accessed via a percutaneous needle/introducer through which the leads are placed adjacent to the left and right medical branch. The leads are then connected to a battery powered stimulator which is surgically inserted under the skin of the buttock or lower back. Once the system is set-up, it can be controlled by the patient using a handheld remote controller. Products used within a procedure may include but not limited to: • Electrodes • Implantable pulse generator • Patient programmer • Tunnelling tool • Patient magnet
