A new blood pressure implant device has been developed by German scientists and significantly reduces blood pressure by sending signals to the brain. The recent development demonstrates how sending electrical signals to the brain can help sustain normal blood pressure.
Published in the Institute of Physics (IOP) Publishing’s Journal of Neural Engineering, the study showcases a new device that uses 24 individual electrodes which are integrated into a micro-machined cuff. The device wraps itself around the vagal nerve which stimulates various organs. Only identifying bloop pressure influenced fibres, the device picks up signals from sensors.
Dr. Dennis Plachta, who is the lead author of the study, stated in IOP:
“Our proof-of-concept interface has shown that it is possible to use the left vagal nerve to reduce blood pressure without any adverse side effects, which is important for a wide variety of potential treatments that could utilize nerve stimulation without actually penetrating the nerve…As the device will require surgery, it is not intended to be the first port of call for treatment and will come into play when patients, for whatever reasons, are resistant to medication. The long-term goal is to provide ‘treatment-on-demand’ for the patient, whereby the implantable device uses an intelligent circuit to record the activity of the patient, for instance when they are doing exercise, and adjust the blood pressure accordingly.”
Using rats for the study, researchers noticed that the device had a success rate of reducing blood pressure by 40 percent. Moreover, the device did not cause any major side-effects to the animals.
Plachta and his colleagues plan to continue their research and hope to proceed with human trials in the near future.
