Being a global medical technology leader, Boston Scientific Corporation has implanted its first patient with next generation ImageReady MR Conditional pacing system in SAMURAI clinical trial. The study is designed to confirm the safety and effectiveness of the system in the magnetic resonance imaging (MRI) environment.
Pacing systems are designed to treat bradycardia, a condition in which the heart beats too slowly depriving the body of sufficient oxygen. MRI provides detailed images of organs and tissues without the use of radiation. While those images can help clinicians make informed decisions about treatment and care, most pacemakers are not compatible with MRI technology and therefore patients may not have access to the sophisticated scanning capabilities of the diagnostic system.
The next generation ImageReady pacing system is comprised of the Boston Scientific Ingenio MRI pacemaker family and the new INGEVITY MRI pacing leads. The proprietary technology is aimed at reducing MRI interference with device performance. In addition, the INGEVITY pacing lead platform is designed to provide key enhancements in handling and fixation compared to standard leads available today, and is specifically engineered to function in the MRI environment.
"Physicians are very limited in device options and therapies labeled for use in the MRI setting," said Ronald Berger, professor of Medicine, Johns Hopkins Medical Institutions. "The availability of a pacing system specifically designed to allow patients with pacemakers to undergo a broad set of MRI scanning conditions will advance the quality of patient care. The Ingenio MRI pacemaker family also offers pacing technologies not previously available in devices designed for the MRI environment."
The ImageReady pacing system offers technologies exclusive to Boston Scientific, including RightRate rate adaptive pacing with the Minute Ventilation sensor, the only sensor clinically proven to restore chronotropic competence; RYTHMIQ, which is designed to minimize unnecessary RV pacing without clinically significant pauses; and LATITUDE NXT, which is geared towards minimizing clinic and patient burden with wireless remote follow-up.
"The ImageReady system is another example of our continued commitment to meaningful innovation," said Kenneth Stein, chief medical officer, Cardiac Rhythm Management, Boston Scientific. "Our mission is to improve outcomes by providing patients and their physicians with access to the most advanced device therapies and diagnostic technologies."
The SAMURAI trial is a prospective, open-label, two-group randomized, multi-center, global clinical study designed to support US Food and Drug Administration regulatory approval. The trial is expected to enroll approximately 363 patients at 45 centres in seven countries. The first patient implant in the United States occurred at OhioHealth's Riverside Methodist Hospital in Columbus, Ohio by Sreedhar Billakanty, Dr. Billakanty is the co-investigator of the SAMURAI study at OhioHealth along with Gregory Kidwell, MD, system medical director of Electrophysiology Services. The first study implant in the world occurred in Malaysia at the Institut Jantung Negara (Kuala Lumpur) by Razali Omar, MD.
The ImageReady pacing system is under clinical investigation and not currently available for sale in the United States.
