Pennsylvania: A research team at Pennsylvania State University has developed a flexible, biocompatible device - named Caroflex - using 3D printing technology. The device may offer a new approach to treating resistant high blood pressure by delivering gentle electrical pulses to the carotid artery.
According to Oman News Agency, high blood pressure is a widespread global health issue and a leading cause of heart disease and stroke. While most patients can manage the condition with medication and lifestyle changes, some cases do not respond to conventional treatment, even when multiple drugs are used simultaneously.
The device represents a new class of bioelectronics made from soft, flexible materials that mimic the body's natural tissues. It is designed to adhere to biological tissue without the need for surgical stitches, which could otherwise damage blood vessels or surrounding tissue.
The device works by stimulating the baroreceptor reflex - a natural system the body uses to maintain stable blood pressure. These receptors are concentrated in the carotid sinus, a small part of the carotid artery that supplies oxygen-rich blood to the head and neck. When the device sends gentle electrical pulses to this area, the nerve receptors are activated, helping to lower and regulate blood pressure safely.
