Vagal nerve stimulation is a surgical method used to treat epileptic patients. During this procedure, an electrode is implanted in the patient's neck to stimulate the vagus nerve. It is a different approach to surgically removing brain tissue to control epileptic seizures. Epileptic seizures are brought on by brain-wide electrical discharges that are out of control. A different strategy is used in the nerve stimulation process, which involves intermittent electrical stimulation of a nerve outside the brain to affect specific patterns of brain activity. The effectiveness of vagal nerve stimulation in treating patients with epilepsy compared to anti-seizure medications is anticipated to positively impact the market for vagal nerve stimulation.

Market Segmentation

Product Type Insights

The market is bifurcated into implanted VNS devices and external VNS devices. The implanted VNS devices segment is the highest contributor to the market and is expected to grow at a CAGR of 10.78% during the forecast period. For some people with epilepsy, the implantable vagal nerve stimulator is a device that regulates seizures. The implantable vagal nerve stimulator device, in contrast to other types of epilepsy surgery, uses electrical stimulation through the vagus nerve in the neck to reduce subjection instead of performing brain surgery or cutting out a section of the brain. The ability to treat patients without surgery is critical in rapidly expanding the implantable vagal nerve stimulator market.

External vagal nerve stimulation (VNS) devices depend entirely on electrical signals passing through the skin and neck muscles without damaging the tissue they pass through. This process must be exact enough to control and access nerve activity. The vagal nerve stimulator market is anticipated to grow due to technological advances and the introduction of new external VNS devices.

Application Insights

The market is bifurcated into depression and epilepsy. The epilepsy segment is the highest contributor to the market and is expected to grow at a CAGR of 10.19% during the forecast period. A specific kind of neurological disorder is epilepsy. This leads to abnormal brain activity, seizures or periods of strange behavior, and a loss of awareness and sensations. Males and females of all races, ages, and ethnic backgrounds can develop epilepsy. People with epilepsy can control their seizures with medical treatment or surgery. Vagal nerve stimulation, which treats the abnormal behavior pattern of electrical waves in the vagus nerve to comfort the patient, is one of the most efficient and non-surgical treatments for epilepsy.

Depression is a neurological condition that causes constant sadness and boredom. It has an impact on one's emotions, actions, and thoughts. Numerous emotional and physical issues can arise as a result of depression. Angry outbursts, irritability or frustration, sleep disturbances, insomnia, and many other symptoms are signs of depression. People who have depression typically exhibit symptoms that are severe enough to interfere noticeably with daily tasks like work, school, social interactions, or interpersonal relationships. Depression can be treated with a proper diagnosis, therapy, and effective medication. Now that healthcare technology has advanced, depression can be effectively treated using simulation therapies like nerve simulation devices.

End-Use Insights

The market is bifurcated into hospitals and ambulatory surgical centers. The hospital segment is the highest contributor to the market and is expected to grow at a CAGR of 9.89% during the forecast period. In hospitals all over the world, the vagus nerve stimulator is frequently used to treat epilepsy that is resistant to conventional medication. Through the vagus nerve, nerve stimulation therapy prevents seizures by gently electrically stimulating the brain. The VNS therapy aids the patient's quick recovery, less severe seizure control, improved quality of life, and increased alertness. Using VNS devices in hospitals has assisted epilepsy patients in recovering effectively. Still, due to the growth of privately run specialized care facilities globally, its market share may decline over the forecast period.

The locations where non-hospital admission surgeries are called ambulatory surgical centers. In contrast to many hospitals, ambulatory surgical centers offer a more convenient setting and cost-effective services. Patients who choose to have surgery at an ambulatory surgical center arrive on the day of their procedure, have their surgery in a fully furnished operating room and recover while being looked after by trained nurses all without being admitted to the hospital. The ambulatory surgical center segment is anticipated to rule the market soon because of the specialized care and dedicated services offered in these facilities. The need for vagal nerve stimulation will grow significantly in the coming years.
