Cardiac Resynchronization Therapy Devices (CRT)

Cardiac Resynchronization Therapy Devices (CRT) are cardiac electrophysiology (EP) systems that include a small electronic device that is surgically implanted into a pocket of skin to help both ventricles contract together. They are also called biventricular pacemakers. These systems can be used for pacing only, or can include a built-in defibrillator.

Earlier this year, Medtronic began a worldwide pivotal study evaluating its investigational Extravascular Implantable Cardioverter Defibrillator (EV ICD) system to treat dangerously fast heart rhythms. The EV ICD system is designed to deliver lifesaving defibrillation and pacing therapy via a device the same size as traditional, transvenous ICDs, but with a lead (thin wire) placed outside the heart and veins. The future of CRM device technology.

FDA Approves Barostim Neo System for Advanced Heart Failure Patients. Similar to a pacemaker, the Barostim Neo System uses a pulse generator implanted below the collar bone with a lead that attaches to the carotid artery in the neck. It delivers electrical impulses to baroreceptors in the neck, which sense how blood is flowing through the carotid arteries and relays information to the brain. The brain, in turn, sends signals to the heart and blood vessels that relax the blood vessels.
