The world's first implantable system for the treatment of hypertension and heart failure

Release date: 2010-10-15


Ottawa, Canada - Zarlink Semiconductor has announced that its MICS (Medical Implant Communication Service) radio frequency technology is used in the world's first implantable medical device for the treatment of hypertension and heart failure. Developed by CVRx in Minneapolis, the device regulates the patient's blood pressure and cardiovascular function by stimulating the body's natural physiological response. There are nearly 80 million adult patients with hypertension and heart failure in the United States.
"CVRx's Rheos system is a unique treatment that highlights the growing demand for our company's ultra-low-power radio solutions for implantable wireless medical devices," said Zhuo Lian, Senior Vice President, Medical Products Group President and General Manager Steve Sw, a leader in innovative new wireless products, such as CVRx, works together to improve patient care and reduce healthcare costs. ”
The CVRx Rheos system consists of a small pulse generator implanted under the collarbone and two thin wires connected to the carotid sinus. In addition, there is an external programmer using Zarlink's MICS wireless technology, which is used to wirelessly program the pulse generator to activate the receiver located in the carotid sinus. These receivers send chemical signals, and the brain interprets these chemical signals as an increase in blood pressure and heart load, stimulating the brain to improve the heart by taking natural steps such as lowering heart rate, opening blood vessels, and reducing the amount of blood flowing through the kidneys. Vascular function. The wireless link can also be used to adjust the performance of the implanted device to meet the different needs of each patient.
“Our company's Rheos system automatically triggers the body's own natural mechanisms for lowering patients' blood pressure and treating heart-filled patients with heart problems in the event of drug treatment failure,” said Joseph, vice president of product development and operations at CVRx. DuPay said. "Zarlink's high-performance MICS radio technology, medical management experience and technical support are very valuable for accelerating the development of this new system."
According to the American Heart Association, one in every eight deaths worldwide is due to high blood pressure. There are approximately 74 million hypertensive patients in the United States alone. Despite the use of multiple drugs to treat, about 25% of hypertensive patients are unable to control their condition. There are 5.2 million adult heart failure patients in the United States, heart failure, which means that the heart cannot provide enough blood flow to meet the needs of the body. Heart failure greatly increases the risk of sudden cardiac death and can lead to serious problems in the quality of life of patients, who feel shortness of breath, intolerance to exercise and edema.
Zarlink's ZL70102 MICS radio technology delivers high data rates, ultra-low power consumption and unique wake-up circuitry for wireless performance in medical devices that support advanced monitoring, diagnostic and therapeutic applications. Leading customers have designed Zarlink's MICS technology for their pacemakers, implantable cardiac defibrillators (ICDs), nerve stimulation applications, and related programming and monitoring equipment.
