Deep nerve stimulation consistently reduces blood pressure
A University of Houston biomedical engineer is expanding the study of wireless electrodes to treat hypertension and is reporting that blood pressure and renal sympathetic nerve activity (RSNA) is controlled by bioelectronic treatment. RSNA is often increased in hypertension and renal disease. Researchers integrated a sub-millimeter nerve stimulation circuit with a novel nerve attachment microchannel electrode that facilitates implantation into small nerves and allows external power and DPNS modulation control.
Using this implantable device, his team demonstrated that systolic blood pressure can be lowered 10% in one hour and 16% two hours after nerve stimulation. DPNS induced an initial increase in RSNA during the first 2-3 seconds, followed by a reduction in renal activity and mean arterial pressure, despite the increase in heart rate.
