A Wearable Ultrasonic Vagus Nerve Stimulator: Design and Fabrication of Piezoelectric Transducer Prototypes

Vagus nerve stimulation serves as an approach to manage drug-resistant epilepsy. Focused ultrasound stands out as a unique tool, offering a non-invasive modality for VNS. With its excellent depth of penetration and sub-millimeter focusing capabilities in soft tissue, ultrasound allows for precise targeting of the vagus nerve without the need for...

Transcutaneous Vagus Nerve Stimulation Through an In-Ear Device For Epilepsy Treatment

Several studies have illustrated that Transcutaneous Vagus Nerve Stimulation (t-VNS) is an effective method for epileptic treatment. In contrast to the classical invasive Vagus Nerve Stimulation (VNS) which is already a Food and Drug Administration (FDA) approved therapy for epileptic treatment, t-VNS does not require surgical intervention....

Integrating Ultrasound Neuromodulation and Imaging: A System Concept for a Non-Invasive Image-Guided Vagus Nerve Stimulator

Vagus nerve stimulation (VNS) has been proven to be an effective treatment for patients suffering from drug­-resistant epilepsy. Current vagus nerve stimulators are either implantable devices or bulky, handheld devices. The implant consists of a pulse generator beneath the skin of the chest, connected to electrodes that are wired to the cervical...
