Abbott Unveils World’s 1st Dual-Chamber Leadless Pacemaker System in India

The latest cardiac device enables wireless, beat-to-beat communication between two leadless pacemakers

Global healthcare giant Abbott has launched AVEIR DR, a dual-chamber leadless pacemaker system in India.

According to the company, this is the world’s first dual-chamber leadless pacemaker system in India.

The latest cardiac device enables wireless, beat-to-beat communication between two leadless pacemakers, each smaller than an AAA battery, which allows synchronized pacing of both the upper and lower heart chambers without the need for traditional leads.

Until now, leadless systems could only pace a single chamber (ventricle). The AVEIR DR system extends this to dual-chamber pacing by coordinating two devices, potentially allowing a more natural rhythm for patients requiring synchronized atrial-ventricular pacing.

The AVEIR DR system uses Abbott’s proprietary implant-to-implant communication technology, which allows two miniaturized, leadless pacemakers in the right atrium and the other in the right ventricle to exchange signals in real time, enabling synchronized dual-chamber pacing.

About the AVIER DR system

The AVIER DR system comprises two miniaturized devices that include AVEIR VR, which regulates the lower heart chamber, and AVEIR AR, which manages the upper chamber.

The two devices communicate through high-frequency pulses transmitted via the body’s blood, ensuring continuous coordination while using minimal battery power.

Each device is smaller than an AAA battery and attaches to the heart wall with a small screw-in helix, allowing for easy retrieval or replacement if necessary.

The system also supports real-time pacing analysis during implantation, enabling physicians to confirm device positioning before final fixation.

Reportedly, the AVEIR DR system had received U.S. FDA approval in June 2023, based on the results of the AVEIR DR investigational device study. The clinical data reportedly demonstrated a 98.3 % implant success rate and over 97 % of patients achieving atrio-ventricular synchrony.

With its India rollout, Abbott aims to bring this advanced pacing technology to more patients needing dual-chamber pacing support.

Commenting on the launch in India, Ajay Singh Chauhan, General Manager for Abbott’s Cardiac Rhythm Management business in India, Southeast Asia, Hong Kong, Taiwan, and Korea, said, “Nearly one in three patients who require a pacemaker in India need dual chamber pacing.”

“With AVEIR DR, we are expanding the benefits of leadless pacing to more people, offering a precise, minimally invasive and technologically advanced solution for abnormal heart rhythms,” he added.
