Presently, large groups of patients with various diseases are either intolerant, or irresponsive to drug therapies and also intractable by surgery. For several diseases, one option which is available for such patients is the implantable neurostimulat

Present bioelectronic devices for the treatment of resistant hypertension are based on electric stimulation of the carotid baroreceptors. Left vagus nerve (LVN) stimulation, to modulate the aortic baroreceptor signals has received less attention. Und

OBJECTIVE: Left vagus nerve (LVN) stimulation (LVNS) has been tested for lowering the blood pressure (BP) in patients with resistant hypertension (RH). Whereas, closed-loop LVNS (CL-LVNS) driven by a BP marker may be superior to open-loop LVNS, there

A novel therapeutic approach for treating resistant hypertension could be the use of bioelectronic medicines to achieve blood pressure (BP) control in implanted patients by closed-loop stimulation of the left vagus nerve (LVN). However, such a techno

The antiepileptic effects of the electrical stimulation therapies developed for patients with intractable epilepsies depend critically on the stimulation parameters, including the pulse duration, current, and frequency. Consequently, optimization of

Objectives Surviving long lasting cardiac arrest following accidental hypothermia has been reported after treatment with extra corporeal life support (ECLS), but there is a risk of neurologic injury. Most surviving hypothermia patients have a prolong
