Blood Pressure Regulation

New Device Undergoing Clinical Studies

High blood pressure, the most common cardiac disease, is linked to heart attack, stroke, kidney failure, and vision problems. Over 70 million Americans have high blood pressure, which is the leading cause of stroke and a major contributor to heart attack risk.

For those who have no beneficial reaction to blood pressure regulating medications, treatments, and lifestyle changes, Tampa Bay Heart Institute is participating in a clinical trial for a device that may help you in the future.

The device, called the Rheos® Hypertension (HT) Therapy System and manufactured by CVRx, is an implanted pulse generator, similar to a pacemaker, that uses leads that run through the carotid sinuses to connect to electrodes placed under the carotid artery. The body utilizes its baroreceptors located in the carotid artery and carotid sinus to regulate blood pressure. Upon activation, the Rheos® system sends a signal to the brain to reduce blood pressure.

The implanted device, which goes behind the collarbone, is about the size of a cell phone. The implantation procedure takes about 2-3 hours. Eligible candidates for the procedure would be those who have unsuccessfully attempted to lower blood pressure with medication.
