Vagus Nerve Stimulators Market, by Product Type (Implantable Devices and External Devices), by Application (Epilepsy, Depression & Anxiety, Cluster Headache & Migraine, and Others (Crohn's disease, Dyskinesia, among others)), by End User (Hospitals, Specialty Clinics, and Others (Research Institutions, Ambulatory Surgical Centers, among others)), and by Region (North America, Latin America, Europe, Asia Pacific, Middle East, and Africa) - Size, Share, Outlook, and Opportunity Analysis, 2022 - 2030
Vagus nerve stimulation (VNS) refers to a technique which involves stimulating the vagus nerve including electrical or manual stimulation. Right cervical VNS is effective for treatment of heart failure, while the left cervical VNS is an effective treatment for refractory epilepsy as well as resistant depression. Vagus nerve stimulation can be performed through the use of vagus nerve stimulators, which send mild, regular pulses of electrical energy to the brain via the vagus nerve. Vagus nerve stimulators can either be implanted or used as an external handheld device. Traditionally, a vagus nerve stimulator is surgically implanted under the skin on the chest, while a wire is threaded under the skin which connects the device to the left vagus nerve. Some of the side effects associated with use of vagus nerve stimulators include changes in voice/speech, throat or neck pain, headache, insomnia, indigestion, nausea or vomiting, impaired sense of touch, and others.
Market Dynamics
The increasing prevalence of neurological disorders such as depression, anxiety, epilepsy, migraine, and others, rising technological advancements in vagus nerve stimulators, and increasing adoption of inorganic growth strategies such as acquisitions and collaborations by key players operating in the market are the major factors that are expected to drive growth of the global vagus nerve stimulators market over the forecast period.
For instance, according to an article published by the Neuroepidemiology journal, a peer-reviewed scientific journal, in 2020, it is estimated that the incidence of epilepsy was 61.4 per 100,000 person-years in 2017 with higher incidence in low/middle-income countries (139.0 per 100,000 person-years) than in high-income countries (48.9 per 100,000 person-years).
