Health First Baroflex Activation Therapy (BAT) Barostim® Form
Procedure is not covered
The Baroflex Activation Therapy Device (Barostim®) is considered investigational and experimental. As an unproven therapy, Barostim is NOT considered medically necessary for the treatment of congestive heart failure.
Definitions:
- CHF- Congestive Heart Failure
- The Barostim Neo System Kit - Is a medical device designed to treat CHF. The kit includes an implantable pulse generator (IPG), an implant adapter and implant tool, a carotid sinus lead (CSL), a CSL repair kit, and a wireless programmer system (consisting of a programmer interface, software, and a computer). The IPG is surgically inserted under the collar bone and connected to the carotid artery via a 2 millimeter (mm) electrode. The IPG stimulates the baroreceptors approximately 40 times more frequently than a pacemaker
Description:
Barostim was FDA approved in 2019 as an implanted device for patients with systolic heart failure. The device sends electrical signals to trigger the body’s own natural blood flow regulation system. Unlike a pacemaker, it is not connected to the heart. The device utilizes neuromodulation, the power of the brain and nervous system, to improve the symptoms of patients with systolic heart failure.
A person’s body senses changes in blood pressure and other blood flow changes through pressure sensors (baroreceptors) that are found on the carotid artery and in the carotid sinus. These sensors measure and report blood flow to the brain, which compares it to the body’s needs. The Barostim device is implanted under the collarbone and attached with thin leads to the carotid artery. The implanted device communicates with an external device doctors use to noninvasively regulate the activation energy therapy from the device to the leads.
The device sends electrical pulses to baroreceptors located in the wall of the carotid artery. Baroreceptors trigger the body’s main cardiovascular reflex called the baroreflex, which in turn triggers an autonomic response to the heart. "Autonomic" means it is part of the body’s systems that are not consciously controlled by the brain.
When activated, signals are sent through neural pathways to the brain that responds by telling the:
- Arteries to relax, making it easier for blood to flow through the body and reducing cardiac exertion
- Heart to slow down, allowing more time for the organ to fill with blood
- Kidneys to reduce fluid in the body, lowering both excessive blood pressure and workload on the heart
