FDA Approves BIOTRONIK Entovis Pacemaker System with ProMRI® Technology

BIOTRONIK, a leading manufacturer of cardiovascular medical devices, announced today that the Food and Drug Administration (FDA) has granted approval for its Entovis pacemaker system with ProMRI® technology. The Entovis system allows patients to undergo Magnetic Resonance Imaging (MRI) scans with a limited exclusion zone. FDA approval covers both single chamber (SR-T) and dual chamber (DR-T) Entovis pacemakers when implanted with Setrox pacing leads.

Approximately 50,000 single-chamber pacemakers are currently implanted in the U.S. each year; until now, these patients have not been able to access MRI scans. BIOTRONIK is the first company in the U.S. to offer both single- and dual-chamber pacemakers approved for use in an MRI environment. Also, BIOTRONIK is the first company worldwide to offer the current generation of pacing leads with ProMRI® pacemakers. Setrox, including versions released under other names, is the most used lead in MRI pacemakers on the market today with over 850,000 leads sold worldwide.

“With the Entovis longevity and the history of lead reliability, this is a system that will serve a wide variety of pacemaker patients for the foreseeable—and unforeseen—future needs,” said Carleton Nibley, M.D., electrophysiologist at John Muir Medical Center in Concord and Walnut Creek, California, and a participant in the ProMRI® study.

The Entovis system presents advantages over existing pacemakers approved as MR conditional. Patients with approved Entovis pacemakers and leads need only alert radiology staff of their device and the staff will verify the patient meets the criteria to undergo an MRI scan.

Several million patients are currently implanted with pacemaker systems worldwide, and recent studies estimate that a sizeable portion of them will develop a clinical need for an MRI scan during their lifetimes.1,2 MRI scans often provide improved diagnostic capabilities for certain diseases or conditions that cannot be adequately examined by X-ray, computerized tomography (CT), or ultrasound. However, the strong forces applied during MRIs can have a negative effect on the pacing system and have been contraindicated for pacemaker patients in the past.

FDA approval comes only 16 months after the initial clinical study was launched, and five months after the approval of that study’s expansion to include full-body MRI scans. These studies are required by FDA for product evaluation, and are designed to assess the safety and efficacy of BIOTRONIK’s existing single- and dual-chamber Entovis pacemaker systems and Setrox 53 and 60cm leads during MRI scans. These devices are already commercially available in the U.S., but lacked FDA approval for use in the MRI environment.

“The BIOTRONIK Entovis ProMRI® pacemaker system is the latest example of our commitment to excellence and meaningful innovation in supporting patient treatment and quality of life,” said Paul Woodstock, BIOTRONIK Executive Vice President of Sales and Marketing. “We are proud to be able to satisfy the demand for state-of-the-art devices that allow physicians to deliver optimal care to the increasing number of pacemaker patients who may someday need an MRI.”

Entovis devices include BIOTRONIK Home Monitoring® technology, which provides daily monitoring of the patient’s device, and offer the most advanced physiological therapy available via Closed Loop Stimulation (CLS). The Setrox active-fixation pacing leads have a flexible distal end, fractal coating, and steroid elution to ensure excellent handling and stable fixation, as well as optimal electrical performance.

One of the world’s leading manufacturers of cardio- and endovascular medical devices, BIOTRONIK is headquartered in Berlin, Germany, and represented in over 100 countries by its global workforce of more than 5,800 employees. Several million patients have received BIOTRONIK implants designed to save and improve the quality of their lives, or have been treated with BIOTRONIK coronary and peripheral vascular intervention products. Since its development of the first German pacemaker in 1963, BIOTRONIK has engineered many innovations, including BIOTRONIK Home Monitoring®; the world’s first 4 F-compatible 200mm peripheral stent*; Orsiro, the industry’s first hybrid drug-eluting stent*; and the world’s first implantable cardioverter-defibrillators with ProMRI® technology*.

* Investigational Device: Limited by U.S. law to investigational use.

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management.

While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your conta...

How do you close feedback loops across teams and activities delivering complex multi-tier, cloud, container, serverless, and/or API-based services?
