eVNS (VGuard)

VGuard is a headset device that provides noninvasive transcutaneous Vagus Nerve Stimulation (tVNS) applied to the earlobe. The device delivers mild electrical stimulation that affects the central nervous system. The VGuard headset is indicated for the treatment of Alzheimer disease.

About the problem

The VGuard headset is designated for treatment of Alzheimer disease by providing noninvasive transcutaneous Vagus Nerve Stimulation (tVNS) which helps prevent mental deterioration. VGuard is a prescription device which the physician prescribes and tune for the individual Alzheimer patient.

The monitoring and stimulation information of VGuard headset can be visually displayed, monitored and captured, documented, archived and stored on digital media or transferred through communication channels (like Bluetooth, Wi-Fi, or Ethernet). 

Solution & Technology

The VGuard is the medical device for stimulation (non-invasively) left, auricular branch of vagus nerve. This intervention will modify activity of neuron networks in specific brain areas responsible for memory consolidation, learning and spatial navigation. Because of that the main goal of the device is to help older population with cognitive disfunction to boost memory.

All intended users are patients over the age of 60/65 and with diagnosis of  of Alzheimer’s disease. Exclusion criteria are: artificial pacemarker of the heart, psychiatric diseases, other dementia coexisting, alcohol abuse, drugs abuse, history of sleep disorder and psychoactive drug use.

Traction and market

The novelty of the device is use of electrical stimulation of the auricular branch of vagus nerve in the treatment of cognitive disorders in Alzheimer’s disease. There is no similar device on the market dedicated for older patients suffering from Alzheimer’s disease.

The Medical Device will be working in bluetooth connection with private mobile phone or tablet with dedicated  software.
